NHW Project - new -l8 "very high compression" setting
...mes are less efficient, and so we could save for -l8 setting nearly 2KB per compressed .nhw file in average, will have to improve them... This new -l8 setting has so a good neatness to the detriment of details.It is still experimental, but I find it competitive with x265 (HEVC). Update at: http://nhwcodec.blogspot.com/ Any feedback is very welcome! Cheers, Raphael -------------- next part -------------- An HTML attachment was scrubbed...

NHW Image codec - YCbCr color space
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 sure that it is a polite way to keep posting my project updates on the Theora channel...

NHW Image codec - improvement of precision
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, but I just apply residual coding on the first order wavelet "...

Also, don't forget the option I gave you Ralph, where you can have access to one of my VPSes. We can create a subdomain for free, but if you want something like nhw.com, you'd have to register the domain name yourself, which wouldn't cost too much money.... Then I can help configure it to point to your page on my VPS. I'll host it all for free. You'll have your own user

NHW Image codec - higher quality settings
Hello, Just a very quick message to let you know that I have added a higher quality setting (-h2, +10Ko) and I have added now residual coding on the 512x256 wavelet image for the higher settings.Precision is a little better.-I also still apply the post-processing function on the 512x256 wavelet image for now.- Here is the link for the binaries (as I can not link them in my blog for now):

NHW Project - high compression -l4 setting
Hello, For those interested, I have added a -l4 high compression setting to the NHW codec ( http://nhwcodec.blogspot.com/ ).This setting is very experimental, I have boosted the sharpness for this one, but it can lack of precision on low contrast areas. This setting still maintains a good neatness and when it will be validated, I will then make a new 0.1.4 version for the NHW Project. High compression...

NHW Project - quality improvement for -l4,-l5 settings
Hello, I have improved quality for -l4 and -l5 high compression settings.These settings are now really better and very competitive, I now prefer them compared to x265 (HEVC). Update at: http://nhwcodec.blogspot.com/ I am also working on -l6 quality setting, I can simply increase quantization for it but I am not totally satisfied with this solution for now... Looking for more advanced processing at these compression ratios, like an efficient denoising, as do HEVC, AOM AV1,... Cheers, Raphael ---...

...pression" setting I posted was not really good.Now I have corrected and improved it, and now the -l8 quality setting is really better, more precision and more neatness. I think now it is a good setting, and I have started to compare it with x265 and it can be now competitive.

NHW Image codec - 2 lower quality settings
Hello, I have finally added 2 lower quality settings for the NHW codec: -l1 (-5Ko) and -l2 (-10Ko).I use a quantization of 0.935 and 0.88 (kind of quantization), and I decrease residual coding on the first order wavelet image. I have updated the demo page: http://nhwcodec.blogspot.com/ . These 2 lower quality settings are still experimental.If you could find time, would be interested in any opinion on this approach, and if it could be acceptable or not? Because lower quality settings seem quite difficult with my algorithm... -I prefer not remove higher wavelet coef...
