DICOM Vs PNG Input to the GMIC: Confusion

[hlmhlr]

Hi,

Appreciated for the well written repo. I have following queries:

1. The first part is crop mamgram images, and for this crop_mammogram.py function is simulated. However, the script does not take any Mamogram image (which are always in DICOM format). The functions always take the PNG images even for the cropping. It seems confusing. Can you please clarify this point?
2. To run the crop_mammogram.py.py file, the exam_list_before_cropping.pkl is required, and this file already contains the information of `window_location, rightmost_points, bottommost_points, distance_from_starting_side' points. As per crop_mammogram.py and crop_single.py files, these information are extracted from the cropped image.
3. If I have a mamogram image in DICOM format, how should I proceed with this repo? Which metadata for the initial .pkl file I should obtain from the DICOM metadata?

Your prompt response will be highly regarded!

Kind regards,
