OpenCV 4 with Python Blueprints - Second Edition

Writing an HDR script using OpenCV

The first step of the script is going to be setting up the script arguments using Python's built-in argparse module:

import argparseif __name__ == '__main__':    parser = argparse.ArgumentParser()    img_group = parser.add_mutually_exclusive_group(required=True)    img_group.add_argument('--image-dir', type=Path)    img_group.add_argument('--images', type=Path, nargs='+')    args = parser.parse_args()

    if args.image_dir:        args.images = sorted(args.image_dir.iterdir())

As you can see, we have set up two mutually exclusive arguments—--image-dir, a directory that contains the images, and --images, a list of images that we are going to use. And we make sure that we populate args.images with the list of all the images, so the ...
