similar to: NHW Project - some advice

Hello all, Just a quick message for those interested in the NHW Project.I realize that I have too little time to spend on the project currently and I feel that this year will be very important after 6-7 years for its success or not.I already had some few replies from some companies (and a major one), and they can not spend some time, spend some engineers on my work because there is no

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, I don't have advanced on the NHW codec, but now, as a lot of people, I am following the AOMedia AV1 codec.Just a (late) update of my previous post, there won't be problem in AOM AV1 with the CABAC scheme, as the codec will use Daala's multi-symbol entropy coder and/or ANS.That's great! I have even read on the wiki page, that AV1 will use Daala's PVQ as quantization

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).

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 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, For those interested, I have added a new -l19 "extreme" compression quality setting to the NHW Project.This -l19 quality setting is really competitive with x265 (HEVC) on rather good quality images. An important remark: we can really save 2.5KB in average per .nhw compressed file as the entropy coding schemes are not optimal, especially at extreme compression.I have the fast

Hello, I have just tested new next lower quality settings (-l3 and -l4), I can diminish residual coding but if I increase wavelet coeffs threshold there is more aliasing.And even in the current mid quality settings there is some aliasing, this is the big drawback of the NHW codec. SPIHT algorithm is good for that as for example Rududu codec doesn't have aliasing at all at mid compression and

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, 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

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,

Hello, Nice to post here again! I wanted to give you a quick update of the NHW Project as I met great people on this forum. It is one year that I did not work on the NHW Project.I however made from time to time some visual comparison with other codecs on my spare time. Based on my visual comparison tests and subjective opinion, I can confirm that I still find the NHW Project visually more

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, 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, So thanks to helpful forum feedbacks, I know now that I have to create a website for the NHW Project, make demo pages of the technology, and all that with good visual design.It won't be such easy for me... For example, I can easily supply a description, explanation of the different steps of the algorithm, I can supply images encoded at mid-compression with NHW, x265, WebP, JPEG,...

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, 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
