propainter remove watermark with tracking, entity segmentation

you can use clip for watermark detection, but you don’t know where. fuck. you better train it yourself.

image local contrast enhancement, for removing hard-to-detect watermarks

maybe you can use the same trick (context preserving sliding window) from your search engine to here (image preprocessing)!
