NHW Project - Linux
> How about macOS? Can you give us a build.
I don't have a macOS environment so I won't be able to give you a build.But
it would be also great to have a macOS version.I think now that many bugs
have been corrected, and that the NHW Project can compile ok under clang
and run ok on macOS.
If a forum member, that runs macOS, could give us a build and first let us
know if the code is ok,

Hello Spork,
Thank you very much for your great help!
So ok, let's create a website for the NHW Project! Anyone who wants to help
is very welcome! Do you want we start first with wix.com or rather from
nearly scratch? I think from scratch would be better as we can really do
what we want, but it will be a lot and lot more difficult to make...

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 - high compression (-l6 setting and below)
Hello Spork,
> If you want though, when I find some time, I can work on supporting a
better command line parsing.
Yes that would be great as my command line parsing is not good at all.
> Does your codec compile under Linux? If not, that's something I can try
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

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 - 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

Also, don't forget the option I gave you Ralph, where you can have access
to one of my VPSes. We can create a subdomain for free, but if you want
something like nhw.com, you'd have to register the domain name yourself,
which wouldn't cost too much money.... Then I can help configure it to
point to your page on my VPS. I'll host it all for free. You'll have

NHW Project - fast discrete wavelet transform
Hello,
I forgot in my last reply that my DWT implementation can be speed up, for
example I'm doing for now:
for (;_X1<_E_;_X1++,_RES+=2) //dilatation
{
_RES[0]=_X1[0]<<3;
_RES[1]=(_X1[1]+_X1[0])<<2;
}
then
for (;_X2<_E_;_X2++,_RES+=2) //details
{
_RES[0]-=(_X2[1]+_X2[0])<<1;
_RES[1]+=6*_X2[1]-_X2[2]-_X2[0];

NHW Project - good improvement of very high compression (-l8 to -l13 quality settings)
Hello,
Just a quick message to let you know that I have really improved very high
compression of the NHW Project
from -l8 to -l13 quality settings, and we can still save 2.5KB per .nhw
compressed file.
Actually I am new to very high compression, it is just 3 months that I am
working on it (I put on pause the NHW Project from August 2013 to February
2018 )... And I realize that very high

NHW Project - new -l8 "very high compression" setting
Hello,
The -l8 "very high compression" setting I posted was not really good.Now I
have corrected and improved it, and now the -l8 quality setting is really
better, more precision and more neatness.
I think now it is a good setting, and I have started to compare it with
x265 and it can be now competitive.

NHW Project development
Raphael,
Some 15 years ago I implemented limited functionality Theora in our cameras FPGA (it took me 6 month of hard labor), and then gave up - it is a very crowded space and it is difficult to compete with more advanced codecs. And for our other work we anyway need almost raw image data, so we are using JPEG-based JP4 format (https://community.elphel.com/jp4) that we originally developed for

NHW Image codec - lower quality settings
Hello,
I have improved a little the NHW codec.I have improved the dequantization
in the wavelet HH band, and little improved the -l2 (and lower) quality
setting.I have also added a -l3 lower quality setting (-15Ko, exp), I have
increased the quantization for this other setting, and I start to remove
higher wavelet coefficients, but this is not optimal... The artifacts start
to be noticeable for

NHW Project - some update
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. ??

NHW Project development
Hi Andrey,
Thank you for your answer.Actually, NHW is very low-power so I think it
could be geared toward any hardware.But actually I don't have hardware
skills, so NHW is not a real hardware project for now maybe? I agree with
you that it is extremely difficult (for me) to build a community around
NHW, I'm certainly very bad/underskilled at it.Any help is welcome!
Cheers,

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

NHW Project - AOM AV1 comparison
Hi Silvia,
Thank you very much for your answer! Your opinion is much appreciated.
Your advice is wisdom, but very quickly to rectify or precise my situation,
I am finishing a 2-year job contract and there will maybe be a "vacation"
period before the next contract (if I find one), so I would like to invest
this time for the NHW Project, but that's right that image/video
