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

Of course I will!

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 -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

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 - 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 - 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 - 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 - 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.
> 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 -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 - good quality improvement & encoding speed improvement
Hello,
Just a quick message to let you know that I have made good quality
improvements for very high and extreme compression of the NHW Project (-l8
to -l15 quality settings).The NHW Project starts to be really competitive
with x265 (HEVC) at these very high compression ratios.I even find the NHW
Project visually better than x265 (HEVC) for mid and high compression!
I have also improved encoding

x265 and NHW comparison images posted to https://nhwcodec.blogspot.com/?
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 - 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 - Image comparison
Hello,
Could some of you take a look at the image comparison between the NHW
Project and x265 (HEVC) at high compression, available here:
http://nhwcodec.blogspot.com/ .
I would be very very interested in your opinion, and it would help me to
perfect the NHW Project.For me the NHW Project has more neatness, and x265
has more precision.
Else, I was a little lazy these past months, as I

NHW Project - improvement of -l7 quality setting - more neatness
Hello,
Just a word to let you know that I have improved -l7 high compression
quality setting, thanks to a new processing and I have also corrected an
error in the residual coding.Now it has more neatness/definition.Files size
is also a little smaller (and please keep in mind that the entropy coding
schemes are not optimal for now, so we can save 1.5Ko-2Ko per .nhw file).
Actually I find -l7

NHW Project - speed measurement 2 - very high compression
Hello,
If it could be of interest, here are new speed measurement for -l13 very
high compression setting.
For x265 (HEVC), I use BPG codec, and this time I use -m 0 setting which
uses the fastest encoding setting of x265.I run the .exe 10x times and I
pick the best scores.
So here are the timings at -l13 very high compression:
Encode time: x265 (BPG -m 0): 80ms NHW: 20ms
Decode time: x265
