For this week, I would like to share about cropping the bulk images with the same dimensions in python. This method is useful in some cases that image processing or some steps of computer vision projects. The following python script is to crop all images in a folder and save the result to another folder. I used Pillow image library to crop images.<\/p>\n\n\n\n
