I tried to match code with the algorithms I read about. Finally with some hints from Frank, I managed to understand. (I keep regretting that Dave - who's clearly the originator - writes code that needs again reverse engineering to grasp fully. But it works mostly, and that forgives much :)) > As for wavelets, I'd recommend reading this year SIGGRAPH's paper > "Edge-Avoiding Wavelets and thier Applications": > http://www.cs.huji.ac.il/~raananf/projects/eaw/index.html.
