<div>Hello,</div><div> </div><div>Many thanks for your answer.</div><div><br>Yes, actually the improvements are very slight and hardly visible, I have just tested this version on more images... </div><div> </div><div>At first, I validated this version because there was a slight error in the previous one, typically for "high luminosity" like white points in a black background (like stars in a sky...), some of these points tend to disappear, this version corrects it.</div>
<div> </div><div>But for the improvement of precision, that's right that it is very very slight, globally there is a little more precision on "low contrast details" or "textured areas" (I will have to improve my codec on these areas, but it is the most difficult, at my very humble level, my codec is certainly better on neater parts).So I maybe posted a little quickly, the precision improvement is hardly visible, and certainly even with an image comparison it will be very hard to notice and illustrate it (not a major improvement)...</div>
<div> </div><div>I will have to spend more time and improve it, and make a detailed image comparison (also showing the neatness aspect of my codec...).I am planning to do it.Hope that it is ok? If you would have other suggestion or comment about the codec, please do not hesitate to let me know.</div>

Could you post screenshots of the improvements?<br>
