 Hello,

Quite many people urged me to adapt NHW to any image size, I know that it
is essential but I am very sorry again, but it is a very too much colossal
task for me (and my spare time) currently.

Now, I can find little time to work on micro core improvements for
subjective visual quality. I am actually puzzled because I tried some new
ideas that on paper should work, but when I visually reviewed them, images
were not better, and so surprisingly, it's hard for me to visually improve
the current NHW v0.3.0-rc1 version...

Yes some people also told me that NHW is uninteresting and quite bad
because it has very bad PSNR and SSIM results which are the reference
criteria of evaluation for the industry, but all I can answer to that, yes
it's very controversial, but VVC VTM 12.3 (slowest preset) has
extraordinary PSNR and NHW has extremely bad PSNR, but when you actually
look at the images then I visually prefer the NHW images than VVC ones,
mainly because they have more neatness.VVC has more precision, but to my
taste, neatness is visually more pleasant than precision... -Not to say
that NHW has no post-filters for now that would remove aliasing...-

Cheers,
Raphael
