Hello, I am slowly working on the NHW codec, I think now that I will remove the (multistage) residual coding, because it consumes too much bits while leaving still some artifacts.Instead, it seems better to simply have a finer quantization (and use a quantization step of 4 instead of 8).For the higher compression settings, I will need a good "psycho-visual" quantization to know which wavelet coefficients remove/diminish. I have also new ideas for the compression (entropy coding) scheme.Right now, my compression scheme for the wavelet coefficients is equivalent to ZPAQ -method 4 (but very faster).With my new ideas, I think I can improve compression by 1-2%, which will put my scheme on the same level as ZPAQ -method 5! I haven't made much research, but I would also need better YUV420 2x2 up/down-sampling functions (mines are too basic and not really good).If you would know good ones, do not hesitate to contact me.Maybe a Daala developer could point me to the ones used for Daala still image? With all this, I think I could make a 0.1.4 version, but I don't know when it will be released. Cheers, Raphael -------------- next part -------------- An HTML attachment was scrubbed...
