Description
Reduce halo artifacts that can occur when sharpening.
Requirements:
- - AviSynth 2.5.8 or later
- - Supported color formats: YV12
- - Progressive input only
Required Filters:
- MaskTools2 2.0a48+
- Repair.dll - part of the RemoveGrain package.
Syntax and Parameters
DeHalo_alpha(clip clp, float "rx", float "ry", float "darkstr", float "brightstr", float "lowsens", float "highsens", float "ss")
- rx float = 2.0
- 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.
- Note:
- As usual, the radii for halo removal.
- darkstr float = 1.0
- 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 int = 50
- 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 - ???
