Hello, I don't have advanced on the NHW codec, but now, as a lot of people, I am following the AOMedia AV1 codec.Just a (late) update of my previous post, there won't be problem in AOM AV1 with the CABAC scheme, as the codec will use Daala's multi-symbol entropy coder and/or ANS.That's great! I have even read on the wiki page, that AV1 will use Daala's PVQ as quantization scheme.Wow....

...like to find a sponsor for the NHW Project? Does Xiph would have advice for the NHW Project? Monty, what would be your advice to find a sponsor? For example one of my very first task if I find a sponsor will be to adapt the NHW Project to any size of image. Or for now the industry is focusing on AOMedia AV1 and MPEG HEVC,VVC and there is no place, ressource for another codec? Again if you would have advice to find a sponsor now that the NHW Project is good, do not hesitate to contact me. Many thanks!

Hello, Just a quick message to correct what I have said in my previous post.It finally seems not that easy to code small wavelet coefficients to have a good precision, and SPIHT is certainly a very good algorithm for that, -and I know there are SPIHT experts that can make very good SPIHT-based codecs-.I have chosen a new and different approach, the multistage residual coding, so I will try to

Hello, For those interested, I have added a -l8 "very high compression" setting to the NHW Project. I have added an experimental processing to remove details and preserve neatness.I have also now a fast estimation of entropy of wavelet coefficients and I use it accordingly to the image complexity but it is a very first version... With these new processings, the entropy coding schemes
