Kornia is a differentiable computer vision library for PyTorch.

It consists of a set of routines and differentiable modules to solve generic computer vision problems. At its core, the package uses PyTorch as its main backend both for efficiency and to take advantage of the reverse-mode auto-differentiation to define and compute the gradient of complex functions.

Overview

Inspired by existing packages, this library is composed by a subset of packages containing operators that can be inserted within neural networks to train models to perform image transformations, epipolar geometry, depth estimation, and low-level image processing such as filtering and edge detection that operate directly on tensors.

At a granular level, Kornia is a library that consists of the following components:

Component	Description
kornia	a Differentiable Computer Vision library, with strong GPU support
kornia.augmentation	a module to perform data augmentation in the GPU
kornia.color	a set of routines to perform color space conversions
kornia.contrib	a compilation of user contrib and experimental operators
kornia.enhance	a module to perform normalization and intensity transformation
kornia.feature	a module to perform feature detection
kornia.filters	a module to perform image filtering and edge detection
kornia.geometry	a geometric computer vision library to perform image transformations, 3D linear algebra and conversions using different camera models
kornia.losses	a stack of loss functions to solve different vision tasks
kornia.morphology	a module to perform morphological operations
kornia.utils	image to tensor utilities and metrics for vision problems

Add RandomGaussianBlur with instance-level gaussian kernel generation
Changes

Fixes a comment I put in #691

The current implementation of RandomGaussianBlur is random in the sense of only some instances are augmented given the p probability, with a shared fixed gaussian kernel. This differs from other existing approaches such as torchvision GaussianBlur.

In Torchvision philosophy, the randomness of gaussian blur is on the sampling of the sigma std factor to generate the gaussian kernels. To allow reproducibility of various works that are based on torchvision such as papers on Self-Supervised Learning for example (SimCLR, MoCo, Byol, ...), just to cite this area of work, it would be a great feature to have in Kornia.

I propose a new version of RandomGaussianBlur that takes as an input a sigma tuple to provide bounds for uniform sampling. A filter is then generated independently for each instance following a vectorized process to not provoke a bottleneck.

I renamed the previous RandomGaussianBlur back to GaussianBlur but I can change the names to whatever you feel is best.

I implemented tests to validate the process and everything works except the gradcheck through the module but I don't know why, so I'm more than happy to receive help to debug this aspect.

adopt torch.testing.assert_close

Closes #1029. torch.testing.assert_close will only be shipped with torch==1.9. Thus, this PR should not be merged before.

All files except for test/utils.py are 1-to-1 ports and probably do not need special review, but I let you be the judge of that.

Add boxes V2 as discussed in #1142 (superseed #1177)
Changes

This PR implements #1142 (issue) and superseeds #1177 (pr). It's the same code with the following differences:

It takes the object class approach discussed in #1142.

It creates two new classes: Boxes and Boxes3D. They are torchscript classes to allow to be used in traced / scripted code. Without using torch.jit.script decorator, I faced several strange behaviors when scripting.

Fixes gradient check bugs

Check #1177 for differences with current kornia.geometry.bbox module.

~~#### TODO~~ ~~- Update docs~~ ~~- As suggested by shijianjian in #1177, better explanation and name for *_plus_1 in to_tensor and from_tensor.~~ ~~- Fix gradient check test fail for Boxes3D.to_tensor. I don't understand why it's happening as it's almost an exact copy of Boxes.to_tensor ~~ ~~- ¿Update CHANGELOG? Is this something I should do?~~

TODO to do in future PRs):

Port kornia containers to use them. At least, expose bbox_v2. ~~- Check transforms. Care should be taken since transforms assumes +1 convention. At least, it happens with random flips. Check this article.~~ See #1398. As temporary fix, we use "+1" convention internally. See whole temporary fix is done in commit "07795f9c78468b42ecd96f4d5d2b8df562deecf7".

Make kornia.augmentation.random_crop_generator safer
🚀 Feature

Make kornia.augmentation.random_crop_generator safer.

Motivation

Within kornia.augmentation.random_crop_generator _adapted_uniform is used to generate random starting points for the crop. Since it returns a torch.float, the upper delimiter (high) is increased by one (high = x_diff + 1) and cast to torch.long, which is basically a floor division. While this generates a uniform distribution of the integers, it opens up an edge-case: what if Uniform.rsample (used from _adapted_uniform) returns exactly (or within the precision) high?

from unittest import mock import torch from kornia.augmentation.random_generator import _adapted_uniform batch_size = 1 input_size = (None, 2) size = (None, 1) same_on_batch = True x_diff = input_size[1] - size[1] with mock.patch( "kornia.augmentation.utils.Uniform.rsample", new=lambda self, shape: torch.ones(shape) * self.high, ): x_start = _adapted_uniform((batch_size,), 0, x_diff + 1, same_on_batch).long() print(f"x_start {'<=' if x_start <= x_diff else '>'} x_diff")

x_start should lesser or equal to x_diff, but as you can see

x_start > x_diff

Pitch

Although this edge case is unlikely, I think we should implement this properly. Especially since the fix is trivial:

from typing import Tuple, Union def _adapted_uniform_int( shape: Union[Tuple, torch.Size], low: Union[float, torch.Tensor], high: [float, torch.Tensor], same_on_batch: bool = False, ) -> torch.Tensor: return _adapted_uniform(shape, low, high + 1 - 1e-6, same_on_batch).int() with mock.patch( "kornia.augmentation.utils.Uniform.rsample", new=lambda self, shape: torch.ones(shape) * self.high, ): x_start = _adapted_uniform_int((batch_size,), 0, x_diff, same_on_batch).long() print(f"x_start {'<=' if x_start <= x_diff else '>'} x_diff")

x_start <= x_diff

_adapted_uniform_int has the same signature as _adapted_uniform. The only difference to the above call is that we subtract a small constant from high + 1 to prevent it from being drawn exactly. As long as this constant 1e-6 is smaller than torch.finfo(torch.float).eps ~= 1.19e-7 this should be fine.

Additional Context

I've encountered this while working with kornia.augmentation.random_crop_generator. If this used in other places throughout the code base the fix should be applicable everywhere.

[Question] Significant difference in performance between Kornia and Torchvision image augmentations

I have trained two models that use the same sequence of image augmentations but in Torchvision and Kornia and I’m observing a significant difference in the performance of these models. I understand that despite fixing random seeds, these augmentations might still be different which might cause some difference in the test accuracies, but on average, I assume that both of these models should end with similar accuracies, especially when these values are averaged over multiple seeds. However, this is not the case.

# PyTorch transformation
train_orig_transform = transforms.Compose([
    transforms.RandomResizedCrop(32),
    transforms.RandomHorizontalFlip(p=0.5),
    transforms.RandomApply([transforms.ColorJitter(0.4, 0.4, 0.4, 0.1)], p=0.8),
    transforms.RandomGrayscale(p=0.2),
    transforms.ToTensor(),
    transforms.Normalize([0.4914, 0.4822, 0.4465], [0.2023, 0.1994, 0.2010])
    ])

This is the Kornia version of the above PyTorch transformation


class KorniaAugmentationModule(nn.Module):
    def __init__(self, batch_size=512):
        super().__init__()
        # These are standard values for CIFAR10
        self.mu = torch.Tensor([0.4914, 0.4822, 0.4465])
        self.sigma = torch.Tensor([0.2023, 0.1994, 0.2010])

        self.hor_flip_prob = 0.5
        self.jit_prob = 0.8
        self.gs_prob = 0.2

        self.crop = K.RandomResizedCrop(size=(32, 32), same_on_batch=False)
        self.hor_flip = K.RandomHorizontalFlip(p=self.hor_flip_prob, same_on_batch=False)
        self.jit = K.ColorJitter(brightness=0.4, contrast=0.4, saturation=0.4, hue=0.1, p=self.jit_prob, same_on_batch=False)
        self.rand_grayscale =  K.RandomGrayscale(p=self.gs_prob, same_on_batch=False)
        
        self.normalize = K.Normalize(self.mu, self.sigma)

    # Note that I should only normalize in test mode; no other type of augmentation should be performed
    
    def forward(self, x, params=None, mode='train'):
        B = x.shape[0]
        if mode == 'train':
                x = self.crop(x, params['crop_params'])
                x = self.hor_flip(x, params['hor_flip_params'])
                x[params['jit_batch_probs']] = self.jit(x[params['jit_batch_probs']], params['jit_params'])
                x = self.rand_grayscale(x, params['grayscale_params'])

        x = self.normalize(x)
        return x

Rest of the code for training and testing these models is shared.

These are the training loss and testing accuracy curves for kornia (orange) and torchvision (green)

The difference in test accuracies between the two models is nearly ~11% which is very significant.

I have posted this question on PyTorch discussion forum as well. Could you please give pointers on why this behavior is being observed, is this expected and if not, what could be ways to debug this?

NeRF
Changes

This pull request concerns a draft version of the NeRF algorithm for view synthesis and 3D rendering.

In this PR I included an API class - CameraCalibration, which drives NeRF, and is designed based on the discussion in #1384.

I took a brute force approach and copied the relevant core algorithms from the paper: Wang et al. (2021) - https://arxiv.org/abs/2102.07064. Most algorithm parameters are hard-coded, whereas some of those can be defined in CameraCalibration API.

I tested the full functionality of CameraCalibration in Colab - https://colab.research.google.com/drive/1xiX1Jf572HAN_TN4p-8IPU3CZRRkfhox#scrollTo=yVT7jsvk4ViS. Please let me know if you can run this notebook, or at least able to copy it and modify the relevant paths to make it work with the NeRF version in this PR.

The next steps in this PR, and I foresee, and please comment on each point:

Parameterize the algorithm and export more control to CameraCalibration API (including, e.g., CPU/GPU control, rendering parameters, etc.)

Refactor the code I took from https://arxiv.org/abs/2102.07064 to follow Kornia's standards

Replace core engine component with of-the-shelve algorithms. Here I mainly refer to the rendering part, which is also the most compute intensive. I'm thinking PyTorch3D may have some good alternatives we may want to explore

Supporting arbitrary number of leading dimensions
Description

This is the PR for #1068. These first commits include:

Added perform_keep_shape_video decorator. Utilizing _to_bchw and _to_bcdhw in the decorator.

Fixed some bugs for functions supposed to support any number of leading dimensions, but not due to a hardcode bug.

Added support for the kornia.enhance.adjust.

Further, before moving on, I would like to discuss the following matters

How can I write tests for arbitrary dimensions? Could you suggest some sample?

JIT tests break due to *args and **kwargs in the decorators (currently I skip these tests).

Some users' codes may break when inputs not have shape (b, c, h, w) because some functions use _to_bchw and _to_bcdhw.

Please let me know your comments. Thanks!

Weird behavior of LongestMaxSize
Describe the bug

Hello me again,

I might be doing something wrong with the way I use kornia augmentations, please let me know if it is the case.

I was expecting LongestMaxSize in kornia to perform similarily as the albumentation implementation. Meaning that I can throw any images with different shapes to the the transformation function and get an image with different shapes but similar ratios. The largest size being equal to the value given to LongestMaxSize.

See bellow a small code sample that disturbs me.

import kornia.augmentation as K a = torch.ones((512, 256)) b = torch.ones((512, 756)) print("first try") transfo = K.LongestMaxSize(max_size=256, p=1.) print(transfo(a).shape) print(transfo(b).shape) print("second try") a = torch.ones((512, 256)) b = torch.ones((512, 756)) transfo = K.LongestMaxSize(max_size=256, p=1.) print(transfo(b).shape) print(transfo(a).shape) Outputs: first try torch.Size([1, 1, 256, 128]) torch.Size([1, 1, 256, 128]) second try torch.Size([1, 1, 173, 256]) torch.Size([1, 1, 173, 256])

Expected behavior

I would expect to have the same values for the transformations no matter the order of the elements.

ie transfo(a).shape == torch.Size([1, 1, 256, 128]) and transfo(b).shape ==torch.Size([1, 1, 173, 256])

Am I missing something here ?

Weird Behavior of PadTo and poor documentation
Describe the bug

Hi,

First thank you for this great library, I'm currently trying to switch all my pipeline to kornia instead of albumentation.

I was actually looking for a PadIfNeeded function in Kornia. I finally found that there exists a PadTo function (not available in the documentation website by the way).

However, the behavior of the function is unclear when you pass a larger image "inside a smaller PadTo" (see bellow).

There is also a small typo in the docstring saying : p: probability of the image being flipped.

Reproduction steps

import kornia.augmentation as K import torch a = torch.meshgrid(torch.arange(10), torch.arange(10))[0].float() transform = K.PadTo((5, 5), pad_value=0) transform(a)

Expected behavior

It seems that the transformation returns the upper left corner of the image, without any padding happening of course.

I guess I would expect two possibilities:

raise an error: since the augmentation does not perform anything related to what it's supposed to do -> Error: PadSize should be larger than the input size.

return the original image: this would be equivalent to a pad if needed function.

Environment

kornia='0.6.9' torch='1.12.1+cu113'

Highlights

NeRF API

In this release in we include an experimental kornia.nerf submodule with a high level API that implements a vanilla Neural Radiance Field (NeRF). Read more about the roadmap of this project: https://github.com/kornia/kornia/issues/1936 // contribution done by @YanivHollander

from kornia.nerf import NerfSolver from kornia.geomtry.camera import PinholeCamera camera: PinholeCamera = create_one_camera(5, 9, device, dtype) img = create_red_images_for_cameras(camera, device) nerf_obj = NerfSolver(device=device, dtype=dtype) num_img_rays = 15 nerf_obj.init_training(camera, 1.0, 3.0, False, img, num_img_rays, batch_size=5, num_ray_points=10, lr=1e-2) nerf_obj.run(num_epochs=10) img_rendered = nerf_obj.render_views(camera)[0].permute(2, 0, 1)

Improvements, docs and tutorials soon!

Edge Detection

Added kornia.contrib.EdgeDetection API that implements dexined: https://github.com/xavysp/DexiNed

import kornia as K from kornia.contrib import EdgeDetection edge_detection = EdgeDetector().to(device) # preprocess img = K.image_to_tensor(frame, keepdim=False).to(device) img = K.color.bgr_to_rgb(img.float()) # detect ! with torch.no_grad(): edges = edge_detection(img) img_vis = K.tensor_to_image(edges.byte())

Image matching bugfixes:

After testing kornia LoFTR and AdaLAM under big load, our users and we have experiences some bugs in corners cases, such as big images or no input correspondences, which caused pipeline to crash. Not anymore!

SOLD2 line segment detector & descriptor

Contributed by SOLD2 original authors

Geometry-aware matchers: AdaLAM & FGINN
Good old Lowe ratio-test is good for descriptor matching (implemented as `match_snn`, `match_smnn` in kornia, but it is often not enough: it does not take into account keypoint positions. With this version we started to add geometry aware descriptor matchers, starting with [FGINN](https://arxiv.org/abs/1503.02619) and [AdaLAM](https://arxiv.org/abs/2006.04250). Later we plan to add something like SuperGlue (but free version, ofc).
AdaLAM works particularly well with kornia.feature.KeyNetAffNetHardNet. AdaLAM is adopted from original author's implementation.

import matplotlib.pyplot as plt import cv2 import kornia as K import kornia.feature as KF import numpy as np import torch from kornia_moons.feature import * def load_torch_image(fname): img = K.image_to_tensor(cv2.imread(fname), False).float() /255. img = K.color.bgr_to_rgb(img) return img device = K.utils.get_cuda_device_if_available() fname1 = 'kn_church-2.jpg' fname2 = 'kn_church-8.jpg' img1 = load_torch_image(fname1) img2 = load_torch_image(fname2) feature = KF.KeyNetAffNetHardNet(5000, True).eval().to(device) input_dict = {"image0": K.color.rgb_to_grayscale(img1), # LofTR works on grayscale images only "image1": K.color.rgb_to_grayscale(img2)} hw1 = torch.tensor(img1.shape[2:]) hw2 = torch.tensor(img1.shape[2:]) adalam_config = {"device": device} with torch.inference_mode(): lafs1, resps1, descs1 = feature(K.color.rgb_to_grayscale(img1)) lafs2, resps2, descs2 = feature(K.color.rgb_to_grayscale(img2)) dists, idxs = KF.match_adalam(descs1.squeeze(0), descs2.squeeze(0), lafs1, lafs2, # Adalam takes into account also geometric information config=adalam_config, hw1=hw1, hw2=hw2) # Adalam also benefits from knowing image size

Geometry conversions

Converting camera pose from (R,t) to actually pose in world coordinates can be a pain. We are relieving you from it, by implementing various conversion functions, such as camtoworld_to_worldtocam_Rt, worldtocam_to_camtoworld_Rt, camtoworld_graphics_to_vision_4x4, etc. The conversions come with two variants: for (R,t) tensor tuple, or with since extrinsics mat4x4.

Quaternion API

More geometry-related stuff! We have added Quaternion API to make work with rotation representations easy. Checkout the PR

>>> q = Quaternion.identity(batch_size=4) >>> q.data Parameter containing: tensor([[1., 0., 0., 0.], [1., 0., 0., 0.], [1., 0., 0., 0.], [1., 0., 0., 0.]], requires_grad=True) >>> q.real tensor([[1.], [1.], [1.], [1.]], grad_fn=<SliceBackward0>) >>> q.vec tensor([[0., 0., 0.], [0., 0., 0.], [0., 0., 0.], [0., 0., 0.]], grad_fn=<SliceBackward0>)

Mosaic Augmentation

We recently included the RandomMosaic to mosaic image transforms and combine them into one output image. The output image is composed of the parts from each sub-image.

The mosaic transform steps are as follows:

Concate selected images into a super-image.

Crop out the outcome image according to the top-left corner and crop size.

>>> mosaic = RandomMosaic((300, 300), data_keys=["input", "bbox_xyxy"]) >>> boxes = torch.tensor([[ ... [70, 5, 150, 100], ... [60, 180, 175, 220], ... ]]).repeat(8, 1, 1) >>> input = torch.randn(8, 3, 224, 224) >>> out = mosaic(input, boxes) >>> out[0].shape, out[1].shape (torch.Size([8, 3, 300, 300]), torch.Size([8, 8, 4]))

Edge-aware blurring

Thanks to @nitaifingerhut

!wget https://github.com/kornia/data/raw/main/drslump.jpg import torch import kornia import cv2 import matplotlib.pyplot as plt # read the image with OpenCV img: np.ndarray = cv2.imread('./drslump.jpg') img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB) # convert to torch tensor data: torch.tensor = kornia.image_to_tensor(img, keepdim=False)/255. # BxCxHxW data-=0.2*torch.rand_like(data).abs() plt.figure(figsize=(12,8)) edge_blurred = kornia.filters.edge_aware_blur_pool2d(data, 19) plt.imshow(kornia.tensor_to_image(torch.cat([data, edge_blurred],axis=3)))

v0.5.0(Mar 17, 2021)
Kornia 0.5.0 release

In this release we have focus in bringing more classic Computer Vision functionalities to the PyTorch ecosystem, like morphological operators and more diversity with Deep Local Descriptors, color conversions and drawing functions. In addition, we have worked towards improving the integration with TPU and better support with Torchscript.

Highlights

Morphological Operators

As a highlight we include a kornia.morphology that implements several functionalities to work with morphological operators on high-dimensional tensors and differentiability. Contributed by @Juclique

Morphology implements the following methods: dilation, erosion, open, close, close, gradient, top_hat and black_hat.

from kornia import morphology as morph dilated_image = morph.dilation(tensor, kernel) # Dilation plot_morph_image(dilated_image) # Plot

See a full tutorial here: https://github.com/kornia/tutorials/blob/master/source/morphology_101.ipynb

Deep Descriptors

We have added a set of local feature-related models: MKDDescriptor #841 by implemented and ported to kornia by @manyids2; also we ported TFeat, AffNet, OriNet from authors repos #846.

Here is notebook, showing the usage and benefits of new features. We also show how to seamlessly integrate kornia and opencv code via new conversion library kornia_moons.

Also: exposed set_laf_orientation function #869

Video Augmentations

We include a new operator to perform augmentations with videos VideoSequential. The module is based in nn.Sequential and has the ability to concatenate our existing kornia.augmentations for multi-dimensional video tensors. Contributed by @shijianjian

import kornia import torchvision clip, _, _ = torchvision.io.read_video("drop.avi") clip = clip.permute(3, 0, 1, 2)[None] / 255. # To BCTHW input = torch.randn(2, 3, 1, 5, 6).repeat(1, 1, 4, 1, 1) aug_list = VideoSequential( kornia.augmentation.ColorJitter(0.1, 0.1, 0.1, 0.1, p=1.0), kornia.augmentation.RandomAffine(360, p=1.0), data_format="BTCHW", same_on_frame=False) ) out = aug(input)

See a full example in the following Colab: https://colab.research.google.com/drive/12dmHNkvEQrG-PHElbCXT9FgCr_aAGQSI?usp=sharing

Draw functions

We include an experimental functionality draw rectangle implemented in pure torch.tensor. Contributed by @mmathew23

rects = torch.tensor([[[110., 50., 310., 275.], [325., 100., 435., 275.]]]) color = torch.tensor([255., 0., 0.]) x_out = K.utils.draw_rectangle(x_rgb, rects, color)

Deprecated kornia.contrib module.

max_pool_blurd2d is now in kornia.filters

Dropped support of Pytorch 1.5.1 #854

Warp and Crop

We refactored the interface of the functions warp_perspective, warp_affine, center_crop, crop_and_resize and crop_by_boxes in order to expose to the user the needed parameters by grid_sample [mode, padding_mode, align_corners]. #896

The param align_corners has been set by default to None that maps to True in case the user does not specify. This comes from the motivation to match the behavior of the warping functions with OpenCV.

Example of warp_perspective:

def warp_perspective(src: torch.Tensor, M: torch.Tensor, dsize: Tuple[int, int], mode: str = 'bilinear', padding_mode: str = 'zeros', align_corners: Optional[bool] = None) -> torch.Tensor:

v0.4.0(Aug 6, 2020)
Kornia 0.4.0 release

In this release we are including the following main features:

Support to PyTorch v1.6.0.

Local descriptors matching, homography and epipolar geometry API.

3D augmentations and low level API to work with volumetric data.

Highlights

Local features matching

We include an kornia.feature.matching API to perform local descriptors matching such classical and derived version of the nearest neighbour (NN).

match_nn

match_mnn

match_snn

match_smnn

import torch import kornia as K desc1 = torch.rand(2500, 128) desc2 = torch.rand(2500, 128) dists, idxs = K.feature.matching.match_nn(desc1, desc2) # 2500 / 2500x2

Homography and epipolar geometry

We also introduce kornia.geometry.homography including different functionalities to work with homographies and differentiable estimators based on the DLT formulation and the iteratively-reweighted least squares (IRWLS).

import torch import kornia as K pts1 = torch.rand(1, 8, 2) pts2 = torch.rand(1, 8, 2) H = K.find_homography_dlt(pts1, pts2, weights=torch.rand(1, 8)) # 1x3x3

In addition, we have ported some of the existing algorithms from opencv.sfm to PyTorch under kornia.geometry.epipolar that includes different functionalities to work with Fundamental, Essential or Projection matrices, and Triangulation methods useful for Structure from Motion problems.

3D augmentations and volumetric

We expand the kornia.augmentaion with a series of operators to perform 3D augmentations for volumetric data BxCxDxHxW. In this release, we include the following first set of geometric 3D augmentations methods:

RandomDepthicalFlip3D (along depth axis)

RandomVerticalFlip3D (along height axis)

RandomHorizontalFlip3D (along width axis)

RandomRotation3D

RandomAffine3D

The API for 3D augmentation work same as with 2D image augmentations:

import torch import kornia as K x = torch.eye(3).repeat(3, 1, 1) aug = K.augmentation.RandomVerticalFlip3D(p=1.0) print(aug(x)) tensor([[[[[0., 0., 1.], [0., 1., 0.], [1., 0., 0.]], <BLANKLINE> [[0., 0., 1.], [0., 1., 0.], [1., 0., 0.]], <BLANKLINE> [[0., 0., 1.], [0., 1., 0.], [1., 0., 0.]]]]])

Finally, we introduce also a low level API to perform 4D features transformations kornia.warp_projective and extending the filtering operators to support 3D kernels kornia.filter3D.

More 2d operators

We expand as well the list of the 2D image augmentations based on the paper AutoAugment: Learning Augmentation Policies from Data.

Semi-automated GPU tests coverage.
Documentation has been reorganized [docs]
Data augmentation API compatible with torchvision v0.6.0.
Well integration with ecosystem e.g. Pytorch-Lightning.

For more detailed changes check out v0.2.1 and v0.2.2.

Highlights

Data Augmentation

We provide kornia.augmentation a high-level framework that implements kornia-core functionalities and is fully compatible with torchvision supporting batched mode, multi device cpu, gpu, and xla/tpu (comming), auto differentiable and able to retrieve (and chain) applied geometric transforms. To check how to reproduce torchvision in kornia refer to this Colab: Kornia vs. Torchvision @shijianjian

import kornia as K
import torchvision as T

# kornia

transform_fcn = torch.nn.Sequential(
  K.augmentation.RandomAffine(
    [-45., 45.], [0., 0.5], [0.5, 1.5], [0., 0.5], return_transform=True),
  K.color.Normalize(0.1307, 0.3081),
)

# torchvision

transform_fcn = T.transforms.Compose([
  T.transforms.RandomAffine(
    [-45., 45.], [0., 0.5], [0.5, 1.5], [0., 0.5]),
  T.transforms.ToTensor(),
  T.transforms.Normalize((0.1307,), (0.3081,)),
])

Ecosystem compatibility

Kornia has been designed to be very flexible in order to be integrated in other existing frameworks. See the example below about how easy you can define a custom data augmentation pipeline to later be integrated into any training framework such as Pytorch-Lighting. We provide examples in [here] and [here].

class DataAugmentatonPipeline(nn.Module):
    """Module to perform data augmentation using Kornia on torch tensors."""
    def __init__(self, apply_color_jitter: bool = False) -> None:
        super().__init__()
        self._apply_color_jitter = apply_color_jitter

        self._max_val: float = 1024.

        self.transforms = nn.Sequential(
            K.augmentation.Normalize(0., self._max_val),
            K.augmentation.RandomHorizontalFlip(p=0.5)
        )

        self.jitter = K.augmentation.ColorJitter(0.5, 0.5, 0.5, 0.5)

    @torch.no_grad()  # disable gradients for effiency
    def forward(self, x: torch.Tensor) -> torch.Tensor:
        x_out = self.transforms(x)
        if self._apply_color_jitter:
            x_out = self.jitter(x_out)
        return x_out

kornia.augmentation as a framework

In addition, we have re-designed kornia.augmentation such in a way that users can easily contribute with more operators, or just use it as a framework to create their custom operators.

Each of the kornia.augmentation modules inherit from AugmentationBase and one can easily define a new operator by creating a subclass and overriding a couple of methods.

Let's take a look at a custom MyRandomRotation . The class inherits from AugmentationBase making it a nn.Module so that can be stacked in a nn.Sequential to compute chained transformations.

To implement a new functionality two things needed: override get_params and apply

The get_params receives the shape of the input tensor and returns a dictionary with the parameters to use in the apply function.

The applyfunction receives as input a tensor and the dictionary defined in get_params; and returns a tuple with the transformed input and the transformation applied to it.

class MyRandomRotation(AugmentationBase): def __init__(self, angle: float, return_transform: bool = True) -> None: super(MyRandomRotation, self).__init__(self.apply, return_transform) self.angle = angle def get_params(self, batch_shape: torch.Size) -> Dict[str, torch.Tensor]: angles_rad torch.Tensor = torch.rand(batch_shape) * K.pi angles_deg = kornia.rad2deg(angles_rad) * self.angle return dict(angles=angles_deg) def apply(self, input: torch.Tensor, params: Dict[str, torch.Tensor]): # compute transformation angles: torch.Tensor = params['angles'].type_as(input) center = torch.tensor([[W / 2, H / 2]]).type_as(input) transform = K.get_rotation_matrix2d( center, angles, torch.ones_like(angles)) # apply transformation output = K.warp_affine(input, transform, (H, W)) return (output, transform) # how to use it # load an image and cast to tensor img1: torch.Tensor = imread(...) # BxDxHxW # instantiate and apply the transform aug = MyRandomRotation(45., return_transformation=True) img2, transform = aug(img1) # BxDxHxW - Bx3x3

Improvements

Bug Fixes

Kornia v0.2.0 release is now available.

The release contains over 50 commits and updates support to PyTorch 1.4. This is the result of a huge effort in the desing of the new data augmentation module, improvements in the set of the color space conversion algorithms and a refactor of the testing framework that allows to test the library using the cuda backend.

Highlights

Data Augmentation API

From this point forward, we will give support to the new data augmentation API. The kornia.augmentation module mimics the best of the existing data augmentation frameworks such torchvision or albumentations all re-implemented assuming as input torch.Tensor data structures that will allowing to run the standard transformations (geometric and color) in batch mode in the GPU and backprop through it.

In addition, a very interesting feature we are very proud to include, is the ability to return the transformation matrix for each of the transform which will make easier to concatenate and optimize the transforms process.

A quick overview of its usage:

import torch import kornia input: torch.Tensor = load_tensor_data(....) # BxCxHxW transforms = torch.nn.Sequential( kornia.augmentation.RandomGrayscale(), kornia.augmentation.RandomAffine(degrees=(-15, 15)), ) out: torch.Tensor = transforms(input) # CPU out: torch.Tensor = transforms(input.cuda()) # GPU # same returning the transformation matrix transforms = torch.nn.Sequential( kornia.augmentation.RandomGrayscale(return_transformation=True), kornia.augmentation.RandomAffine(degrees=(-15, 15), return_transformation=True), ) out, transform = transforms(input) # BxCxHxW , Bx3x3

This are the following features found we introduce in the module:

BaseAugmentation (#407)

ColorJitter (#329)

RandomHorizontalFlip (#309)

MotionBlur (#328)

RandomVerticalFlip (#375)

RandomErasing (#344)

RandomGrayscale (#384)

Resize (#394)

CenterCrop (#409)

RandomAffine (#403)

RandomPerspective (#403)

RandomRotation (#397, #418)

RandomCrop (#408)

RandomResizedCrop (#408)

Grayscale

GPU Test

We have refactored our testing framework and we can now easily integrate GPU tests within our library. At this moment, this features is only available to run locally but very soon we will integrate with CircleCI and AWS infrastructure so that we can automate the process.

From root one just have to run: make test-gpu

Tests look like this:

import torch from test.common import device def test_rgb_to_grayscale(self, device): channels, height, width = 3, 4, 5 img = torch.ones(channels, height, width).to(device) assert kornia.rgb_to_grayscale(img).shape == (1, height, width)

v0.1.4(Oct 5, 2019)
Table of Contents

We have just released Kornia: a differentiable computer vision library for PyTorch.

It consists of a set of routines and differentiable modules to solve generic computer vision problems. At its core, the package uses PyTorch as its main backend both for efficiency and to take advantage of the reverse-mode auto-differentiation to define and compute the gradient of complex functions.

Inspired by OpenCV, this library is composed by a subset of packages containing operators that can be inserted within neural networks to train models to perform image transformations, epipolar geometry, depth estimation, and low level image processing such as filtering and edge detection that operate directly on tensors.

It has over 300 commits and majorly refactors the whole library including over than 100 functions to solve generic Computer Vision problems.

Highlights

Version 0.1.4 includes a reorganization of the internal API grouping functionalities that consists of the following components:

kornia | a Differentiable Computer Vision library like OpenCV, with strong GPU support.

kornia.color | a set of routines to perform color space conversions.

kornia.contrib | a compilation of user contrib and experimental operators.

kornia.feature | a module to perform local feature detection.

kornia.filters | a module to perform image filtering and edge detection.

kornia.geometry | a geometric computer vision library to perform image transformations, 3D linear algebra and conversions using differen camera models.

kornia.losses | a stack of loss functions to solve different vision tasks.

kornia.utils | image to tensor utilities and metrics for vision problems.

Big contribution in kornia.features:

Implemented anti-aliased local patch extraction.

Implemented classical local features cornerness functions: Harris, Hessian, Good Features To Track.
