- Some japanese pornography has been "censored". Some of the censoring is done by simply inverting
pixel-aligned boxes, intended to, like ROT13, be trivial to undo. However, it's still usually a
manual process. Is it possible to automatically identify the bounding boxes for these areas?
Hints:
- brightness is obviously inverted... and while a good clue, there are often abrupt
brightness changes... ESPECIALLY in hentai, where black lines bound brighter areas
- more clearly, hue is shifted in a very specific manner
