I want to reproduce the quality to scan of an APP, that app get images like this one: RGB image and produce good results, like this: image procesed. I have already used adaptiveThreshold, adaptative_thresholding, otsu filter, etc, but they all just throw me in binary. I do not get the effect of removing noise from paper and obtaining the lines of the image in gray scale. Any idea about to solve this problem?
How to reproduce this digital document scan effect using python?
