Hello, Just a very quick message to let you know that I have definitely switched to YCbCr color space as YCbCr is better, more precision.I have updated my demo page: http://nhwcodec.blogspot.com/ . Any comment on this new version from the Xiph Community would be very appreciated, as I am developing alone (it really took some time to switch to YCbCr...).Also (as it was said), I am not totally

...let me know if you would share the opinion that NHW is globally better than x265 (HEVC) at high compression on rather good quality images.Any feedback would be much appreciated!!! Many thanks!

Hello, I don't have advanced on the NHW Project this past month, but I have definitely validated its characteristics and this new version. The NHW Codec preserves or enhances image neatness and sharpness, which translates that on good quality images the NHW Codec is globally better than HEVC, and on degraded (with blur, artifacts) images it is worse than HEVC because it lacks of precision. I

...could claim that Xiph has reviewed the source code and find that the NHW codec is royalty/patent-free (better than me alone claiming this...).Maybe it was in this sense that Ralph Giles answered me?

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

Hi again, I have improved precision of my codec (on the encoder and decoder).I have also improved the -h1 quality setting.-Source code and binaries at http://nhwcodec.blogspot.com/-. I am still trying to improve precision of my codec, with keeping my low-complexity (fast) approach. I do not totally use the reference (and impressive) block prediction with different modes + residual coding scheme,

Hello, I don't have advanced (and worked) on the NHW codec recently.I however compiled the codec with gcc -O3 setting (the binaries are available from my demo page: http://nhwcodec.blogspot.com ) and just with this optimization (no mmx, sse, avx instructions,... ) the NHW codec is 6x faster to encode and 4x faster to decode than WebP.As I state that my codec is royalty-free, fast with more
