NHW Project - lower quality settings
I don't mind at all. I imagine there are more people like me out
there who have been following your work, but haven't said anything.
I agree that a series of pages explaining how things work may lead to
more contributions. At the very least it would lead to more people
being better educated on how wavelets work in image compression. But,
this is your project, if you don't have the

NHW Project - lower quality settings
Hi David!
Many thanks for your very encouraging and kind feedback!!! (Hope you don't
mind that I made your post public on the Theora channel).
I try to be the more sincere as I can in my posts.Some people suggested me
to make demo pages to explain how the codec works step by step, and I
realize that it would be good, because certainly it will show that the NHW
codec is not that complex and

NHW Project - lower quality settings
Hello,
I have re-tested -l4 high compression setting and it's clear that it lacks
of precision on degraded, rather blurred images. So I don't know if it is a
good idea to base the other lower quality settings (-l5,-l6,...) on -l4
setting.I have tested the NHW codec against x265, x264, Daala, WebP,
Rududu, DLI and it's clear that at high compression these very good codecs
have more

NHW Project - high compression (-l6 setting and below)
Hello Ken,
Many thanks for your reply!
Yes, I very need to adapt the NHW codec to any image size.But actually it
is the least interesting part, I don't think that it is that difficult
(compared to creating high compression settings) but it is very boring,
annoying... Really not the part that I prefer... For now, as I am jobless,
my aim is to have "pleasure" with the NHW Project and

NHW Project - high compression (-l6 setting and below)
Hello Spork,

better command line parsing.
Yes that would be great as my command line parsing is not good at all.

to work on as well.
I never tested my codec under Linux )-:, and so it would be also great to
compile it under Linux.I think

quality improvement of -l4, -l5, -l6 high compression settings
Hello Dave,
Thank you very much for your support and your interest.
Actually so few people took a look at the NHW Project, but with this
version the NHW Project is becoming very interesting, it is royalty-free
and very fast furthermore.
Really if you could find time, I would be very interested in any opinion
from the Xiph.org community!
Cheers,
Raphael

NHW Project - quality improvement for -l4,-l5 settings
Hello,
I have improved quality for -l4 and -l5 high compression settings.These
settings are now really better and very competitive, I now prefer them
compared to x265 (HEVC).
Update at: http://nhwcodec.blogspot.com/
I am also working on -l6 quality setting, I can simply increase
quantization for it but I am not totally satisfied with this solution for
now... Looking for more advanced processing

NHW Project - high compression (-l6 setting and below)
Hello,
I would like to thank very much the Theora channel community for their
support and help!!! And even recently a Theora channel member proposed me
to freely host on his server the NHW Project website, to present the codec
on the embedded processors, MCU forums that he knows well, another member
forked my GitHub repository!!! Really thank you very much!!!
It makes me think that maybe the NHW

NHW Project - major quality improvement for -l1->-l4 settings
Hello,
With -l5 quality setting, I have learned that I can increase wavelet coeff
threshold to 12 in the HH band without noticeable difference in the
reconstructed images.With this processing, I win in average 1Ko in the
compressed .nhw files, and so I can raise the quantization for -l1->-l4
settings (0.935->0.955,0.88->0.9,0.87->0.89) and so these settings are now
better, there is a

NHW Project - high compression -l4 setting
Hello,
For those interested, I have added a -l4 high compression setting to the
NHW codec ( http://nhwcodec.blogspot.com/ ).This setting is very
experimental, I have boosted the sharpness for this one, but it can lack of
precision on low contrast areas.
This setting still maintains a good neatness and when it will be validated,
I will then make a new 0.1.4 version for the NHW Project.

NHW Project - quality improvement for -l6, -l7 quality settings
Hello all,
Just a quick message to let you know that I have improved -l6 and -l7 high
compression settings.
These settings are notably better now, with more neatness and more
precision.I find them competitive with x265 (HEVC) now!!!
Update at: http://nhwcodec.blogspot.com/
Else I realize that the strength of the NHW Project is that it is
royalty-free, and competitive with the great x265 codec

NHW Project - quality improvement for -l5 setting
Hello,
Just a quick message to let you know that I have improved the -l5 quality
setting.I have suppressed a data info packet and so I have raised
quantization for this setting.This setting has now more precision and is
better.
Update at: http://nhwcodec.blogspot.com/
I am still working on -l6 and below high compression settings, but it is
not that easy, as I want to stay competitive with x265

Well, if you want to pursue a collaborative project, you need to
attract others to work on it. Perhaps 'demo'

NHW Project - news with Xiph.org
Hello,
These last 2 months, I have talked again with Monty Montgomery about the
NHW Project and he told me that Xiph.org would like to encourage the NHW
Project development.That's just great!
I'll see what Monty will do on his side (and when he has time), but he also
told me that the NHW codec has merits but there must be an effort to
demonstrate them.

NHW Project - lower quality settings - high compression
Hello,
I was testing quickly some other lower quality settings -l3, -l4 because
high compression is what really lacks to the NHW codec.
In fact I can remove -5Ko of residual coding on Y,U,V comps for -l3 and I
can remove -10Ko always of residual coding for -l4, and -l3, -l4 settings
will be really better than the current ones implemented.
I can also increase the wavelet coefficients threshold
