Lifting Detail from Darkness
skapps, John P. Lewis · 2001
This application sketch describes a high quality method for separating detail from overall image region intensity. This intensity-detail decomposition can be used to automate some specialized image alteration tasks. Our work was motivated by the movie 102 Dalmatians, which featured a dalmatian puppy without spots. Animal handlers determined that the obvious idea of applying makeup to the dog was not possible evidently there was no suitable makeup that was both safe to the dogs and that would stay in place during normal dog activity (including licking). This left Disney TSL with the task of painting out all the spots on the dog every few frames (the paintings were carried for a few frames with a simple scheme).
