Pascal Massimino	d73e63a726	add DequantizeLevels() placeholder ... will be called by alpha post-processing, although doing nothing for now. Gradient smoothing would be nice-to-have here. Patch welcome! Change-Id: I534cde866bdc75da22d0f0a6d1373c90e21366f3	2012-05-22 02:28:19 -07:00
Pascal Massimino	3e863dda61	remove tcoder, switch alpha-plane compression to lossless ... * Method #1 is now calling the lossless encoder on the alpha plane. Format is not final, it's just a first draft. We need ad-hoc functions. * removed now useless utils/alpha.* * added utils/quant_levels.h instead * removed the TCoder code altogether Change-Id: I636840b6129a43171b74860e0a0fc5bb1bcffc6a	2012-05-21 06:24:48 -07:00

Vikas Arora	e1947a9299	Add Alpha encode/decode code. ... Add code for Alpha encoding & decoding. The alpha compression is done via backward reference counts encoded with Arithmetic encoder (TCoder). Also provided is lossy Alpha pre-processing option via level-quantizations using kNN heuristic. Change-Id: Ib6b13530c1a4ab6493edcb586ad29fe242bc1766	2011-11-30 17:53:09 +05:30
