S-Spline

[CAFxX]

i was thinking about the possibility to port the S-Spline (the one in PhotoZoom) algorithm to avisynth, since for upsizing anime material it seems to me that it could do very well.
the problem is that I can't even find a generical description of the algorithm (best would be to find ready-to-use c code, but i don't think i'm going to find it easily). anyone ever found some paper about S-Spline?

Well, I don't think you will find the S-Spline propietary ( ? ) algo anywhere.
Almost the same results can be obtained using EDI interpolation.In fact I'm sure S-spline is using some kind of EDI in a combo with some other filters .

any link to EDI sources?
(actually my aim is to write a resizing/enhancement avisynth plugin for animated material, so any other suggestion on different approaches is welcome)
