[theora] NHW Project - some update

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 have made tests on 100 images from
the Internet.

The NHW Project still lacks very high compression, and I think now I will
inspire from HEVC, that is to say, I would like to strongly remove details
and preserve the contours, edges. It is not that easy to code, and again
any help would be very very welcome! Again if you can provide any help to
the NHW Project, do not hesitate to show up, would be so much appreciated!!!

The NHW codec has a high speed, which makes it a good candidate for mobile,
embedded devices.There are currently some exploration for a MotionJPEG
replacement on low power processor (dual-core 240MHz Xtensa LX6) where
MotionJPEG appears to be too heavyweight.

With the recent updates, I think the NHW Project is still patent-free and
royalty-free. And just the fact that it is royalty-free, should be worth
the try.

So with this new version, I hope the NHW Project could attract a company
that would like to sponsorize the project (to adapt the codec to any size
of image for example).

Very quickly to finish, I have seen that on the Theora mailing list there
are employees from big companies.This can be indiscreet and very impolite,
but for example there are 2 employees from Apple who are on the Theora
channel mailing list... Does Apple can be interested in such a codec as the
NHW Project? If not, what does it lack to be of interest? Would you have
some advice?

Many thanks again!
Cheers,
Raphael

I think Apple is somehow "attached" to the MPEG group. They control the
"pools" too. Your codec sounds great. Google could -- if they wanted to --
use it but they have Web^M and webP. Look to Asia. Asus has just launched a
new phone. ??

Hello Dave!

Thank you very much for your answer!

You're right.I have thought that the new next-generation codecs like JVET
(MPEG) VVC, AOM AV1, XVC will be too computational-intensive for mobile
phones.So the de facto codecs for mobiles devices are H.264 and HEVC, I
thought that my codec that is royalty-free and a lot faster could move the
lines, but you're right Apple is "attached" to MPEG and Google and the
others are "attached" to AOM.

I am always very attracted by new opportunities for my NHW Project! But
don't you think there will be a problem of compatibility? For example a
company wants to use the NHW Project in its new mobile phone, but what will
happen if the NHW Project is not supported by web browsers?

Anyway, I am very interested to look to Asia, would you have some advice?

Cheers,
Raphael

Hello Dave,

Thank you very much again to believe in the NHW Project and spend some of
your precious time in the help of the project! This is much appreciated!

I know it will be very very difficult, and even a Theora forum member
answered me few months ago that it is totally impossible that a company
uses my codec in their mobile phones, and I tend to share that opinion.

For now, and it's great, their is a study to replace MotionJPEG with the
NHW Project for low power processors -that don't have enough power for
MotionJPEG-.

But again Dave, if you would have any advice, if you could indicate me a
person/company to contact but I know it's extremely difficult, it would be
so much exceptional!

Many thanks again for your consideration Sir!
Best regards,
Raphael
