NHW Project - a free state-of-the-art image/video compression codec

Hello,

For those interested, I have released the 0.2.9.3 version of NHW.

I have modified the quantization scheme.Based on psychovisual tuning, this new version has more precision, but a little less neatness.

Hope it was a good decision, as I maybe did not test on enough images...

Hello,

Just a very quick update for those interested, I have released the 0.2.9.4 version of NHW.I have fine-tuned the quantization in the encoder, and so this new version is better, with notably a little more precision and a little more neatness.

Hello,

I am continuing to improve/fine-tune the quantization in NHW, and so I have released the new version 0.2.9.5.

-I tried to simplify/clean up the quantization code but I didn't have same results... so for now the quantization code is a little complicated but it works well...-

I find that this new version is better and has quite an interesting balance between neatness and precision.

Hello,

For those interested, I have released the 0.2.9.6 version of NHW.This new version has a better quantization based on psychovisual fine-tuning.

As NHW is still extremely fast, I hope in 2023 it could find some interest within niche applications.

Hello,

For those interested, I have released the 0.2.9.7 version of NHW.I am continuing to improve the quantization, and so this new version is visually better, with a better balance between neatness and precision.

Hello,

I forgot to let you know that the new version 0.2.9.7 also improves the high quality settings (-q17 to -q23, previously -l3 to -h3), if it might interest those who test at high quality.

Hello,

I found time to study a little deeper the new version of the high quality settings in NHW, it was 10 years that I did not work on them! Actually new quantization step is imperfect, in the sense that it is not coded in the feedback-loop-correction, but it seems this version that gives the best visual results.Maybe it would need more extensive tests (and I really lack time), but (in the past) there were quite many people interested in NHW high quality settings, and I would be really interested to know what would they think of this new version?

Very quickly to finish, as some people remarked me, yes I am more relaxed now, NHW is a good hobby project (and nothing more), and of course I won't be angry and won't insist if it doesn't lead to a commercial/industry application... (and also anyway my last chance was with the niche market as NHW is extremely fast, but they don't seem interested, so I am more cool now, NHW will stay an experimental hobby project for my spare time...)

Hello,

Really hope that I am not disturbing you, but for those interested, I have improved quantization in NHW, and so now it is visually better, with a better balance between neatness and precision.

As it is a small modification and correction, I did not release a new version but I have updated the binaries.

I know I am publishing a lot of incremental updates, but my aim is to release/reach the 0.3.0 version in march, because after I think I will not have time to work on NHW on that pace anylonger.

Cheers,
Raphael
