Description

pSharpen performs two-point sharpening to avoid overshoot.

Requirements

Required Plugins

Additional planar colorspaces are supported when using AviSynth 2.6 and corresponding MaskTools2.

Syntax and Parameters

pSharpen (clip clp, int "strength", int "threshold", float "ss_x", float "ss_y", int "dest_x", int "dest_y")


clip   =
Input clip


int  strength = 25
Determines the strength of the sharpening (up until the overshoot correction threshold, see below). Value of 100 will set all pixels to either their local min or max; value of 0 will make the filter do nothing. Range: 0 to 100


int  threshold = 75
Determines how close to the min/max a pixel can be sharpened before the overshoot correction (compression) kicks in. Higher values make the overshoot correction more of a hard limiting, while lower values soften the compression. Value of 0 makes the filter do nothing. Range: 0 to 100


float  ss_x = 1.0
float  ss_y = 1.0
The horizontal and vertical supersampling factors, respectively. Higher values will reduce aliasing, at the expense of speed.


int  dest_x = clp.width()
int  dest_y = clp.height()
Final image size; defaults to the dimensions of the input clip.


Examples

pSharpen with default settings:

AviSource("Blah.avi")
pSharpen(strength=25, threshold=75, ss_x=1.0, ss_y=1.0)
