Required Filters
- MaskTools2
- Repair.dll - part of the RemoveGrain package.
Parameters
DeHalo_alpha(clip clp, float "rx", float "ry", float "darkstr", float "brightstr", float "lowsens", float "highsens", float "ss")
- rx, ry float = 2.0
- Range: 1.0 - 3.0
- As usual, the radii for halo removal.
- Note: This function is rather sensitive to the radius settings.
- Set it as low as possible! If radius is set too high, it will start missing small spots.
- Set it as low as possible! If radius is set too high, it will start missing small spots.
- Note: This function is rather sensitive to the radius settings.
- As usual, the radii for halo removal.
- darkstr, brightstr float = 1.0
- Range: 0.0 - 1.0 [<0.0 and >1.0 possible]
- The strength factors for processing dark and bright halos. Default 1.0 both for symmetrical processing.
- On Comic/Anime, darkstr=0.4~0.8 sometimes might be better ... sometimes.
- In General, the function seems to preserve dark lines rather well.
- lowsens, highsens int = 50
- Range: 0 - 100
- Sensitivity settings, not that easy to describe them exactly ...
- In a sense, they define a window between how weak an achieved effect has to be to get fully accepted, and how strong an achieved effect has to be to get fully discarded.
- Defaults are 50 and 50 ... try and see for yourself.
- ss float = 1.5
- Range: 1.0 - ???
- Supersampling factor, to avoid creation of aliasing.
- Range: 1.0 - ???
