Hello,

For those interested, I have released the NHW v0.3.0-rc7 new version.

I am still continuing to fine-tune the nhw_kernel weights.This new version has then more precision and a better visual quality.

-Don't know how much I will continue to fine-tune/refine the nhw_kernel weights, as I find that this stage is not far from paranoid now...-

Cheers,
Raphael

Maybe instead, really think about working on increasing the possible resolution, even when it means rewriting tons of code.
Tuning for some 'neatness' when nobody looks at the results seems like wasted time, especially if you are not sure that tuning holds true for higher resolutions.

I think the tuning for neatness in NHW is ok with all resolutions of image.For example (and don't know if it is a good example), with larger images, if you extract 512x512 parts of these larger images, then the tuning seems still OK.

I also wanted to point out that another main aspect of NHW is its very good speed, and the fast decoder can be even speed up, for example by disabling some heavy processings that only bring marginal improvement...

Cheers,
Raphael

I concur on this. Among other things, with modern high dpi displays, few people look at 512x512 at anything like pixel-level detail. That's just 3% the area of a 2160p display.

So visual comparisons would happen zoomed in, which is also a pretty unnatural way to look at an image. Which makes it hard to really get a sense of how the algorithm itself would compare to others in real-world circumstances.

Even 1024x1024 would be a lot easier to visually evaluate, even if arbitrary resolutions are a big challenge.

Hi,

For those interested, I have released the NHW v0.3.0-rc8 new version.

I continue to fine-tune the nhw_kernel weights and pre_processing.This new version seems then to have more precision and a better visual quality.

-Just a quick note, for now I can not explain why it works...-

More at: http://nhwcodec.blogspot.com/

Do not hesitate to let me know if you agree with this new version, else I can still revert the commit...

Cheers,
Raphael

Hello,

For those interested, I have released the NHW v0.3.0-rc9 new version.

I continue to fine-tune the pre-processing.This new version has then more precision and a little better visual quality.

No problem, yes I get used to post my updates/new versions on a weekly basis, and yes I realize this can be quite disturbing on Doom9 for such kind of projects.

Would Doom9 members prefer that I post here each 3 or 6 months with a "big" major release rather than weekly incremental updates?

Cheers,
Raphael

Thank you

I also wanted to temperate as I am really not sure that I will continue for longtime to post weekly releases as I have other priorities that I should really care about now...

Hello,

Just a quick message, I am still trying to improve precision of NHW while still keeping its neatness, but yes I realize that I have bored you for many years with neatness, asserting that it was visually more pleasant than precision, but as I advance and improve NHW (notably its precision), I really don't know what to think now, maybe precision is more important than neatness?... -It maybe depends on your type of screen?-...

Nevermind, I wanted to remind that a main point while considering NHW is its extreme speed, NHW is a lot faster to encode and decode, which again seems to make it well-suited for niche applications which need low-power.-I don't have contact with the niche industry, but that's right if they could delegate ressources (a team to help me), it could be possible to turn NHW into something usable, like notably working with any arbitrary image resolutions-...

Very quickly to finish, you certainly already have seen it, I wanted to send congratulations to the AVIF team for the CLIC 2024 Challenge.Apparently the results are ranked by order, and as you can see, it's very impressive but notably, despite that ECM 10 optimized for still image (ED codec) has +2dB PSNR compared to AVIF at high compression (which is out of this world), but CLIC compression challenge professional reviewers said that AVIF has the best visual quality and is the visually more pleasant for them, that's very impressive!

Cheers,
Raphael
