quality improvement of -l4, -l5, -l6 high compression settings
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!

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 2018-04-28 21:40 GMT+02:00 Dave

NHW codec - progress 2
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

NHW Project - new -l8 "very high compression" setting
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

NHW Project - speed comparison with x265
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

NHW Project - some results
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

NHW Image codec
Hello, Ok, and that's too many work to review a source code.In my codec, I have 3 compression schemes, I think 2 are not patented, but the third... I don't know.For the rest, I think my codec is patent-free (I don't use SPIHT,EZW,zerotree methods), even the wavelet transform is new and don't use the lifting scheme nor the convolution product. Else, if you found time to review the

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 - 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. ?? On Mon, Jul 9, 2018, 3:14 PM Raphael Canut <nhwcodec at gmail.com> wrote: > Hello, > > I don't have advanced on the NHW

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-...

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 compression,

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

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. The advantages, merits of the NHW

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

Hello, First I have added a link on my demo blog page to Google Drive for the image comparison folder of NHW and x265 on rather good quality images.But be sure, as soon as you have sent me a free alternative host, I will upload there too! Link (for now) on: http://nhwcodec.blogspot.com/ Do not hesitate to let me know if you would share the opinion that NHW is globally better than x265 (HEVC) at

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
Hello, I don't have advanced (and worked) on the NHW codec recently.I however compiled the codec with gcc -O3 setting (the binaries are available from my demo page: http://nhwcodec.blogspot.com ) and just with this optimization (no mmx, sse, avx instructions,... ) the NHW codec is 6x faster to encode and 4x faster to decode than WebP.As I state that my codec is royalty-free, fast with more
