...sponding wavelet coeff in the next-order decomposition bigger than threshold2 then this wavelet coefficient is not zeroed... I will try to do this "basic" work in the next days and will let you know if it is acceptable and competitive.I think I could add ideally with this another -5,-10,-15Ko in compression but for higher compression I think I must introduce a new approach like GANs maybe (generative adversarial networks) but I don't know if it will fit my speed and low-memory consumption goals... Stay tuned. Cheers, Raphael -------------- next part -------------- An HTML attachmen...

...W decoder that is supposed to remove aliasing but it doesn't work at all (and I still haven't removed it...).Would you know an efficient processing, algorithm that removes aliaising? It would help me a lot!!! Because the next quality settings could be here: -l3,-l4,-l5,-l6 with -5Ko,-10Ko,-15Ko,-20Ko corresponding roughly to 1.5bpp->1bpp (for image not video) with the processings explained above. Then for the next settings, I could start to increase quantization of the DC parts, and have a better analysis of wavelet coefficients, this is the most difficult part. So again, I think it...

Hello, I have improved a little the NHW codec.I have improved the dequantization in the wavelet HH band, and little improved the -l2 (and lower) quality setting.I have also added a -l3 lower quality setting (-15Ko, exp), I have increased the quantization for this other setting, and I start to remove higher wavelet coefficients, but this is not optimal... The artifacts start to be noticeable for some images at -l3 setting (even if the neatness would be still good...), really need to better modelise the wavele...
