Hello, For those interested, I improved a little the NHW codec.Now I apply a (fast) sharpening on U and V components before the 2x2 upsampling in the decoder, which results in a better upsampling (+0.1dB for the PSNR...) and gives a better precision to the image.I have also improved the dequantization in the wavelet HH band.
