similar to: NHW Project - quality improvement for -l6, -l7 quality settings

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

Hello, Just a quick message to let you know that I have improved -l6 quality setting. This high compression quality setting is now competitive with x265 (HEVC).Actually I prefer -l6 high compression setting compared to x265 on many images (not blurred)... Update at: http://nhwcodec.blogspot.com/ Else, do some of you could test the NHW Project under Linux? Many thanks! Cheers, Raphael

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

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

Hello all, Just a quick message to let you know that I have added to the NHW Project a -l7 high compression quality setting. This setting is still experimental and can be improved, but actually (I am certainly not objective) I find it competitive with x265 (HEVC), mainly because it has a good neatness. Update at: http://nhwcodec.blogspot.com/ You can also find sample 512x512 test bitmap images

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

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

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

Of course I will!

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!

Cool, I'll check it out.

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 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

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

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, 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

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

Hello, The -l8 "very high compression" setting I posted was not really good.Now I have corrected and improved it, and now the -l8 quality setting is really better, more precision and more neatness. I think now it is a good setting, and I have started to compare it with x265 and it can be now competitive. More at: http://nhwcodec.blogspot.com/ Do not hesitate to test it and give me

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, 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
