Is there any reason why mdegrainN is less efficient than mdegrainX, where x=1…6? I am not talking about speed but about denoising.
I was doing some tests on noise vs details preservation and I panned from mdegrain4 to mdegrain9 as tr=4…9 parameter in SMDegrain. It was the only parameter I changed. The table speaks for itself:
tr=4 5.237,20 kb/s
tr=5 5.116,45 kb/s
tr=6 5.021,69 kb/s
tr=7 5.067,22 kb/s <- at this point there is a regression
tr=8 5.008,13 kb/s
tr=9 4.963,75 kb/s
I have tried different thsad values and I have found the same pattern.
Any idea?
