In the previous article, you can see that the image size is 1920*1080*3. Now if you cut it into a 1000*1000*3 image, you can of course read the grayscale image.
from skimage import io picture = io.imread("C:/Users/huyuan/Pictures/Camera Roll/1.jpg")# Picture path io.imshow(picture)
""" Center crop an image of any size (with the center as the origin) """ slice_width, slice_height, _ = img_data.shape if slice_width < 1000: raise Exception( "The width of image must be at least {} pixels!".format(SLICE_WIDTH)) # The width of the image should be greater than the width 512 you want to crop elif slice_height < 1000: raise Exception( "The height of image must be at least {} pixels!".format(SLICE_HEIGHT)) # The height of the image should be greater than the height 512 you want to crop width_crop = (slice_width - 1000) // 2 height_crop = (slice_height - 1000) // 2 if width_crop > 0: img_data = img_data[width_crop:-width_crop, :, :] if height_crop > 0: img_data = img_data[:, height_crop:-height_crop,:] io.imshow(img_data)
Result: cropped image
