...the NHW codec). Visually, I prefer the results of NHW codec on nearly 18 images out of 30 (60%), I find that more neatness is more pleasant, I prefer the results of x265 on 11 images (35%), more precision is more pleasant, and on 1 image the result of NHW codec is quite bad (looks terrible, lots of aliaising, annoying imprecisions). First, do you agree with these results? Second, is it acceptable that a codec is better than another in 60% of the cases but perform quite badly in 5% of the cases? I would be very interested in your opinion on this subject. Very quickly to finish, my codec really need im...

...that I will increase aliasing and it will become no more acceptable... I have coded a post-processing function in the NHW 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...

I'm trying to use ESS & xemacs under debian linux testing and KDE. My problem is that I didn't find any document in the internet explaining a **step by step** session with R and xemacs. The (wrong) procedure I follow (to no avail!) is: 1) I start R in a terminal window; 2) I start xemacs and open a file with the extension .R (test.R); 3) I issue M-x R RET and I can see an Rd new
