| − | # Tries to clean up slight ringing around edges by heavily AWarpSharp-ing the
| + | |
| − | # image and then applying it only to the areas where the difference is small
| + | |
| − | # enough so detail isn't destroyed.
| + | |
| − | #
| + | |
| − | # Currently only processes the chroma, as that's what sharpeners that cause the
| + | |
| − | # ringing in the first place operate on.
| + | |
| − | #
| + | |
| − | # depth ........ Depth of the AWarpSharpening
| + | |
| − | #
| + | |
| − | # diffthresh ... differences between the source and the sharpened clip larger
| + | |
| − | # than this will not be touched; the smaller the difference the
| + | |
| − | # more of the sharpened clip will be used
| + | |
| − | #
| + | |
| − | # lumathresh ... since the ringing is mostly notable in bright places this
| + | |
| − | # threshold will prevent dark areas from being hit too hard, so
| + | |
| − | # for instance linework will be preserved
| + | |
| − | #
| + | |
| − | # debug ........ 0 - normal operation
| + | |
| − | # 1 - return sharpened clip
| + | |
| − | # 2 - return diffthresh mask

| − | # 3 - return lumathresh mask

| − | # 4 - return combined mask

| + | I uploaded an updated [[aWarpSharpDering]] script. The original script used the ancient MaskTools so it can absolutely be considered deprecated. - [[User:Reel.Deal|Reel.Deal]] 13:58, 15 June 2015 (CEST) |
