Hello, I am still working on very high compression for the NHW Project, but I find the current version good, it has a good neatness of image, which I find visually more pleasant than other codecs that are optimizing for PSNR, SSIM,... Furthermore the NHW Project is still very fast and royalty-free. I dedicated this past year to the NHW Project and I could make very good improvements (like

Hello, I have (slowly) worked these last couple weeks on the psychovisual model of NHW because some people reproach me that it washes details out... so I restored a little more details but this consumes some bits and actually it turned out that it also decreases neatness, and so when you compare at the same compression ratio, actually I find the current version visually better because it has a

Hello, I have just added a new -l18 "extreme" compression quality setting to the NHW Project.I find this quality setting very good and actually better than x265 (HEVC). First, I wanted to let you know that compression of the wavelet DC image is really not efficient at extreme compression, I have the fast ideas to improve it, and so we can really save 2.5KB per .nhw compressed files in

Hello, For those interested, I have added a new -l17 "extreme" compression quality setting to the NHW Project.I find this setting competitive with x265 (HEVC).Actually I have tested -l17 on 15 rather good quality images, and on these images I prefer the results of the NHW Project. We can still save 2.5KB per .nhw compressed files. More at: http://nhwcodec.blogspot.com/ . I start

Hello, I have added a new -l16 "extreme" compression quality setting to the NHW Project. This new -l16 quality setting is surprisingly good actually, because I find it better on some images than -l15 quality setting whereas files size is smaller.I notably find this new -l16 quality setting better than x265 (HEVC). More at: http://nhwcodec.blogspot.com/ We can still save 2.5KB per

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

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

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

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

Hello, These last 2 months I have been in contact with a very impressive and friendly engineer from Intel who has written an article on my codec and the 4-5 new codecs in general that competes with HEVC.He finally answered me that as Intel is a founding member of the Alliance for Open Media and chairs several MPEG WG around HEVC, they won't be able to put extra resources on the NHW Project.So

Hello, Ok that's right HEVC and AOM AV1 are better than the NHW codec, even at mid compression.I only tested my codec with quite neat images, hence the good results, but on more blurred, more compressed images, HEVC and AOM AV1 are definitely better, they are also exceptionnal at high compression. So, yes that's right, the NHW codec has very little chance to penetrate the market, it is

Hello, For those interested, I have released the NHW v0.3.0-rc29 new version. I continue to fine-tune the nhw_kernel weights.This new version has then more precision and a better visual quality. I have made a "deeper" visual review at -q14 compression setting which is "high" compression, and I find now that at this setting NHW has a competitive precision with AVIF and VVC.If

Hello, I wanted to let you know that I have released a new -l13 very high compression quality setting for the NHW Project (and we can still save 2.5KB per .nhw compressed file). I find this -l13 quality setting very competitive (I will maybe use some of its processing to improve -l12 setting).Compared to x265 (HEVC), I have tested on 15 rather good quality images, and I visually prefer the

Hello, I would like to discuss a little about the NHW codec and its state after nearly 5 years on the Xiph forums. I also know that if I would like to discuss I'd better go to the great Doom9 and Encode.ru forums but for now I find that my codec is too experimental for these professional forums: - the codec is only for fixed 512x512 size, just a test tool. - there is only mid compression -

Hello, I don't have worked on the NHW Project this past week (I also have to work on an other project) but I found time today to make an "extensive" testing of x265 (HEVC) and the NHW codec at high compression (-l7 setting). That's right that x265 is a very good codec! Really impressive.The NHW Project is not as good, it can only compete with x265 (HEVC) on quite high quality

Hello all, It's me again.Just a quick message to tell that I finally do not agree that HEVC (don't have tested AOM AV1 for now) is better than the NHW codec at mid compression. Last night, I dowloaded 30 images of Star Wars Rogue One on the web and I made another comparison with x265 (HEVC) for mid compression (-l2 to h2 settings for the NHW codec). Visually, I prefer the results of NHW

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

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
