Read images to numpy arrays

Last update: Jan 07, 2023

Overview

mahotas-imread: Read Image Files

https://api.travis-ci.com/luispedro/imread.png

IO with images and numpy arrays.

Mahotas-imread is a simple module with a small number of functions:

imread: Reads an image file
imread_multi: Reads an image file with multiple images. Currently, TIFF and STK (a TIFF sub-based format) support this function.
imsave: Writes an image file

Example (which uses mahotas for Gaussian filtering):

from imread import imread, imsave
from mahotas import gaussian_filter
lena = imread('lena.jpeg')

lena = gaussian_filter(lena.astype(float), 4.)
imsave('lena-filtered.jpeg', lena)

This grew out of frustration at current image loading solutions in Python, in either my packages [mahotas] or packages from others [scikit-image, for example].

The relationship with numpy is very contained and this could be easily repurposed to load images in other frameworks, even other programming languages.

Online documentation

Python versions 2.6, 2.7, 3.3+ are officially supported.

Python 3.2 (and earlier versions in the Python 3 series) are officially not supported. Patches will be accepted if they do not mess up anything else, but bug reports will not be considered as very high priority.

Citation

If you use imread on a published publication, please cite the main mahotas paper (imread is a spin-off of mahotas):

Installation/Dependencies

The easiest environment to install mahotas-imread is anaconda, through conda-forge. Just use:

conda config --add channels conda-forge
conda install imread

To compile on debian/ubuntu:

sudo apt-get install libpng12-dev libtiff4-dev libwebp-dev
sudo apt-get install xcftools

To compile on Mac:

sudo port install libpng tiff webp

Either way, you can then compile with:

python setup.py build

and install with:

python setup.py install

On Windows, you can also just download a pre-built package from C. Gohlke's repository

On nix, you can use:

nix-env -iA nixpkgs.python27Packages.imread

or use the pkgs.python27Packages.imread object in your *.nix files.

Comments

wheels?

I noticed that https://github.com/luispedro/imread/issues/23 discussed uploading wheels.

Has that effort been stalled?I ask because imread is being used by scikit-image to test the imread backend. Installing imread from source sometimes breaks the build system.

We also had to create a special case for it since it did not have "wheels" so we couldn't recommend our users install it by default as a general "optional dependency".

Here is an example of a troublesome build https://travis-ci.org/scikit-image/scikit-image/jobs/530681267

imsave does not work with 16-bit PNGs

First of all I want to thank you for developing the library, and especially the 16-bit PNG support. I think I've found a bug in it, though: It seems that saving 16-bit RGB data does not work properly. Only the first 5 columns in the generated file have the expected values, others contain some garbage. Note that 8-bit read/write and 16-bit read are working fine.

I'm running imread version 0.6 on 64-bit Ubuntu 14.04, tested on both Python 2.7.6 and 3.4.3.

Error in greyscale conversion during imread

I'm using the macport py27 versions of imread, mahotas, and numpy. When I load image_0011.jpg from the "ant" category of the Caltech 101 dataset, I receive the error

" in () ----> 1 image = mahotas.imread('/Users/*****/datasets/caltech101/data/ant/image_0011.jpg', as_grey=True)

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/imread/imread.pyc in imread(filename, as_grey, formatstr) 50 # these are the values that wikipedia says are typical 51 transform = np.array([ 0.30, 0.59, 0.11]) ---> 52 return np.dot(im, transform) 53 return im 54

ValueError: objects are not aligned"

This particular image is already greyscale, so essentially, imread isn't checking to ensure that the image has three channels. I'm not sure if this is intended behaviour and isn't noted in the documentation, or the check wasn't implemented.

Wheel building repository

Hi,

I just made a repository that will build Linux and OSX wheels for imread, here:

https://github.com/MacPython/imread-wheels

travis-ci builds the wheels:

https://travis-ci.org/MacPython/imread-wheels

and uploads them to:

https://3f23b170c54c2533c070-1c8a9b3114517dc5fe17b7c3f8c63a43.ssl.cf2.rackcdn.com

I've given @luispedro admin permission to the wheel building repo. The README at the top level of the repository should be self-explanatory.

Would you consider uploading the built wheels to pypi? I'm happy to do that if you like, I do that for quite a few other projects (numpy, scipy, matplotlib and so on).

Thanks for imread.

Does not build using python3.4

I'm trying to build the imread module using python3.4. I was able to build it using python2 (submitted to the Arch User repository here https://aur.archlinux.org/packages/python2-imread/). However using 3.4 I get the following errors:

PNG reads in inverted

This image (which I hope uploads without change, MD5 = b655482e6c500210caca8950d6ce4bd9) loads in imread 0.3.1incorrectly. It looks right if I xor it with 255, but I don't think that's all that's wrong.

Disabled manual addition of zlib when building on non-linux platforms.

Hi. I was having errors building the latest imread sources on OSX from your repo's master:

https://gist.github.com/4023544#file_error_building_luispedro_source_with_pip.txt

Removing the two lines from setup.py that add zlib to the libraries install list on non-linux systems fixed it -- all the tests ran OK thereafter and the library performed as advertised:

https://gist.github.com/4023544#file_successful_install_build_ext_inplace_and_nosetests_run_with_patch_to_setup_file.txt

I am not sure if adding zlib explicitly is necessary for some other platform, or if indeed this is the way to go, but it was a solution on my end.

Badly readed gray image

Hi, I wanted to read an 8bit png image with imread() function. But the loaded image has incorrectly 3 channels and also strange values in them. I'm using the package downloaded from http://www.lfd.uci.edu/~gohlke/pythonlibs/ (version for python 3.3 32bit). Could you please look at it and tell me if this is a bug or mistake at my side? Thanks.

Write to buffer or return bytes
This is more a question or feature request / idea rather than an issue.

If I am not mistaken it's currently not possible to write to a buffer or return the written bytes somehow right? What do you think about expanding the interface to support something like:

buf = BytesIO() imsave(buf, my_fancy_array, formatstr='png')

If this is out of scope never mind. I am just curious.
