Hello, For those interested, I have developped a (simple) NHW Neatness Metrics to measure neatness between 2 images: the studied one and the reference one. The results are the significance of the neatness on the whole image and the average neatness amount. This work is experimental and could be incomplete for this first version (notably on "blurred" edges, contours)! But the metric shows that the NHW Project has more neatness than the other codecs, notably at high compression where there is more neatness. More at: http://nhwcodec.blogspot.com/ As I am claiming that visually (subjectively) the NHW Project has more neatness, this metric could add objective measurement.-But for now it could still not replace visual evaluation of image.- Many thanks! Cheers, Raphael Canut
