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!
