PSharpen

Revision as of 19:00, 28 November 2015

Description

pSharpen performs two-point sharpening to avoid overshoot.

Requirements

• AviSynth 2.5.8 or greater
• Progressive input only
• Supported color formats: YV12

Required Plugins

• Average
• MaskTools2

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", float "dest_x", float "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.

float  dest_x = 1.0

float  dest_y = 1.0

Final image size.

Examples

pSharpen with default settings:

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