similar to: NHW Project - quality improvement for -l5 setting

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

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

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 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

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, 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, 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 all, Just a quick message to let you know that I have improved -l6 and -l7 high compression settings. These settings are notably better now, with more neatness and more precision.I find them competitive with x265 (HEVC) now!!! Update at: http://nhwcodec.blogspot.com/ Else I realize that the strength of the NHW Project is that it is royalty-free, and competitive with the great x265 codec

Hello, I have improved quality for -l3,-l4,-l5 settings.I have diminished residual coding and I have raised again quantization.These settings are now better. Update at: http://nhwcodec.blogspot.com/ The NHW Project with this version starts to be competitive at high compression with x265. Any feedback welcome! Cheers, Raphael -------------- next part -------------- An HTML attachment was

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

I don't mind at all. I imagine there are more people like me out there who have been following your work, but haven't said anything. I agree that a series of pages explaining how things work may lead to more contributions. At the very least it would lead to more people being better educated on how wavelets work in image compression. But, this is your project, if you don't have the

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, 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, 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, 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

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, 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, I have re-tested -l4 high compression setting and it's clear that it lacks of precision on degraded, rather blurred images. So I don't know if it is a good idea to base the other lower quality settings (-l5,-l6,...) on -l4 setting.I have tested the NHW codec against x265, x264, Daala, WebP, Rududu, DLI and it's clear that at high compression these very good codecs have more
