similar to: NHW Project - quality improvement for -l4,-l5 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 2018-04-28 21:40 GMT+02:00 Dave

Thank you so much Sir!!! If you have time, do not hesitate to let us know what you would think of the NHW Project.Any remark, opinion would be very welcome! Many thanks again!

Hello, I am very slowly working on the NHW Project.I recently made a speed comparison with x265 and wanted to share it with you. On my processor Intel Core i5-6400, in average the NHW encoder (totally unoptimized) is x10 times faster to encode than x265 (png decoding time removed), in average 30ms vs 300ms for a 512x512 24bit color image, and in average the NHW decoder (totally unoptimized) is

Hello, For those interested, I have added a -l8 "very high compression" setting to the NHW Project. I have added an experimental processing to remove details and preserve neatness.I have also now a fast estimation of entropy of wavelet coefficients and I use it accordingly to the image complexity but it is a very first version... With these new processings, the entropy coding schemes

Hello, Just a quick message to let you know that I get back to NHW Project currently. I downloaded 20 images from the Internet with rather good quality (mainly faces), I compressed them at high compression -l7 setting with the NHW Project, and on 19 images out of 20, I visually prefer the results of NHW compared to x265 (HEVC)!!! -I can make available these 20x3=60 512x512 24bit bitmap images

Raphael, I do not believe it is possible to build a viable community around most hardware projects except super-universal based on very cheap/high-volume products like Pi or Arduino. We see the commercial benefits of Free Software/Open Hardware as it adds value to the hardware as users are ready to pay extra for the Freedom.

Hello, I know there is no community around NHW, but I would have liked to know what you would like to see improved in the NHW codec.I know its results are not perfect for now compared to high-end AV1/VVC codecs for example, but could be ok giving its extremely fast speed.-However on high quality images, I notably like its good results because of its neatness.- Regarding things to improve, there

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

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, Raphael Le

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

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

Hello, Ok, I will post them in a folder on Google Drive and will give the link on my blog page, -because among other things, on my blog page, I can not display 2 bitmap 512x512 images side by side-... Hope it is ok! Cheers, Raphael 2018-07-15 1:41 GMT+02:00 J.B. Nicholson <jbn at forestfield.org>: > Raphael Canut wrote: > >> I downloaded 20 images from the Internet with

Hello, I have improved quality for -l3,-l4,-l5 settings.I have diminished residual coding and I have raised again quantization.These settings are now better. Update at: http://nhwcodec.blogspot.com/ The NHW Project with this version starts to be competitive at high compression with x265. Any feedback welcome!

Hello, Just a quick message to correct what I have said in my previous post.It finally seems not that easy to code small wavelet coefficients to have a good precision, and SPIHT is certainly a very good algorithm for that, -and I know there are SPIHT experts that can make very good SPIHT-based codecs-.I have chosen a new and different approach, the multistage residual coding, so I will try to

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 compression,

Of course I will!

Cool, I'll check it out.

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

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 your own user
