Read and write operations

Be careful cv2 The read and write types of are np.array、uint8、255、HWC、RGB

1. imread

io.imread(filename)

• filename： The path to read the file
• as_gray： If you read RGB chart , take RGB Turn into Gray, If it is Gray It does not change ,default=False

Load a picture
Loads an image from a file.

The return property is np.array、uint8、255、HWC、RBG

Code example

from skimage import io
img_color = io.imread('color.jpg')
# img_color2gray = io.imread('color.jpg', as_gray=True) 
img_gray  = cv2.imread('gray.jpg')

2. imsave

io.imwrite(filename, img)

• filename： Path to store
• im： Saved pictures

Save the picture to a specific path filename
Saves an image to a specified file.

Be similar to imread Mirror operation of , What type is read in , What type is it when saving np.array、uint8、255、HWC、RGB

Code example

from skimage import io
img1 = io.imread('color.jpg')
io.imwrite("color2.jpg", img1)

3. imshow

io.imshow(image)

• image： Pictures shown

Show the picture to a specific window
Displays an image in the specified window.

image type np.array、uint8、255、HWC、RGB

It's also easy to use

from imageio import io
img1 = io.imread('color.jpg')
io.imshow("color", img1)
io.show()
