I thought the lossless part of JPEG XL was done by FUIF, am I misunderstanding something?
- janwas 7y agoLossless transcoding of JPEG bitstreams is done by Brunsli, there is also lossless storage of pixels, based on tech from FUIF plus an adaptive predictor by Alex Rhatushnyak.
- JyrkiAlakuijala 7y agoPlus the 'select' predictor from WebP lossless :-)
- jonsneyers 7y agoPlus tons of cross-pollination from the PIK/VarDCT mode, e.g. the (MA)ANS and Brotli entropy coding and the Patches intra/inter block copy mechanism :)
