[theora] NHW Project - website, demo pages, algorithms dev,...
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,... that (visually) show that the NHW codec has more neatness/sharpness than the others, I can supply encode/decode timings that show that unoptimized NHW codec is faster than the other codecs. Unfortunately, I don't have a neatness metrics, I won't be able to create and register a website, and I won't be able to make good graphical illustrations for the technology demos.But if some Xiph community members can help with it, do not hesitate to show up, it would be just great! I also have to keep on improving the NHW codec.Currently I am focusing on the aliasing of the NHW codec, it's the main drawback of the codec.I have certainly missed something because the other codecs AOM AV1, x265, x264, WebP, JPEG, Rududu (wavelet) don't create aliasing.-The NHW codec has other advantages.-This is certainly due to little HF energy preserving.If you have any suggestion, do not hesitate to let me know.I will also have to study more the SPIHT algorithm. Currently, I am more inclined to improve and develop NHW algorithms, it's the part that I prefer... And I feel that I am not very far from making a good codec, for now I prefer the NHW codec to x265, WebP, x264, JPEG, JPEG2000, Rududu and others... mainly because it has more neatness while still maintaining a decent precision (except aliasing).It is also a lot faster, more energy efficient (power consumption) and the NHW Project is totally royalty- and patent- free. So again I think that the NHW Project is an interesting and challenging project, if you think you can help in any way: website, demo pages, algorithms development, advertising,... the NHW Project welcomes new members! Many thanks again! Cheers, Raphael -------------- next part -------------- An HTML attachment was scrubbed...
