SmoothUV bug report
Quote:
If you are talking of the fact radius higher than 7 can't be selected, then this is intended. I don't plan to had radius 7 (that's already a 15x15 kernel) because it's too much hassle for the benefit over radius 6, and it would only be used for that very case. 2) I wrote on my page that it was a simplistic remake of smartsmoother. I've added a part which makes it of higher quality but not HiQ if you properly read the page once again, you'll see the booleans HQY and HQC activate the hiqh quality mode for respectively Y channel and U,V channels. To go deeper into details, it almost works like msmooth: it calculates a local edge value for the current pixel and plane processed, and decrease accordingly the weigh of the smartsmoothed pixel. That leads us to the parameter "strength": the higher it is, the more you'll keep the smartsmoothed version and keep the original. This strength is dynamically modified by edge value in HQ mode: the higher the edge, the less the smartsmoother pixel will be used. The current setting makes it worth for anime I bet, as it is very sensitive to edge: new strength = input strength - 4*edge value Check by yourself how the HQ mode changes the output (strength isn't used in none-HQ mode). 3) tempsmoother? Like the one in the old mpeg2dec? temporalsoften isn't sufficient ? |

from the readme that came with the filter: Radii > 4 (ie 5 and up) are busted. I leave them available for you to check
but consider that a radius of 4 produces a 9x9 convolution kernel. It should be pretty sufficient for most uses. Thtas why i was asking it, but if u say it doesnt pose any problems to use them, i'll beleive ur word for it. as for radii 7+ i wasnt really talking about those, more likr 5,6. Any higher would be useless. I did mean ol tempsmother from mpeg2dec.dll, i tried Tsoften on it, result werent really satisfactory, didnt clean up the noise well. Tempsmoother still does a better job i think on it. |
