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

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

new -l16 "extreme" compression quality setting
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).

NHW Project - more test with x265 (HEVC) codec
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

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 - new -l18 "extreme" compression quality setting
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

NHW codec
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 -

NHW Project - high compression & community
Hello, I've found some time to get back to the NHW Project.In fact a Xiph forum member told me that even if I will start a new job, he hopes that I will still continue to develop a little the NHW Project, on my spare time.I told him that I would furthermore spend my spare time on the NHW Project if a community around the project could emerge... and he told me that certainly the best way for

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 - new -l17 "extreme" compression quality setting
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

NHW Project - new -l19 "extreme" compression quality setting
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

NHW Project - high compression (-l6 setting and below)
Hello, I would like to thank very much the Theora channel community for their support and help!!! And even recently a Theora channel member proposed me to freely host on his server the NHW Project website, to present the codec on the embedded processors, MCU forums that he knows well, another member forked my GitHub repository!!! Really thank you very much!!! It makes me think that maybe the NHW

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 Project - new -l13 very high compression quality setting
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

NHW Project - seeking for new members
Hello, Very sorry I made a mistake, I compared this version with an old one, not with the previous one, and in fact results are the same, there is no improvement actually... Else I would like to have your opinion on how to have more visibility, audience for the NHW Project.I suspect that big companies don't even know that the NHW Project exists or they didn't test it because it seems too

NHW Codec - new study on 30 images
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

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 - high compression (-l6 setting and below)
Hello Spork, > If you want though, when I find some time, I can work on supporting a 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 - 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
