== Description ==
[[pSharpen]] performs two-point sharpening to avoid overshoot.<br>
<br>
== Requirements ==
* AviSynth 2.5.8 or [http://sourceforge.net/projects/avisynth2/ greater]
* [[FAQ_different_types_content#How_do_I_recognize_progressive.2C_interlaced.2C_telecined.2C_hybrid_and_blended_content.3F|Progressive]] input only 
* Supported color formats: [[YV12]]

=== Required Plugins ===
*[[Average]]
*[[MaskTools2]]
Additional [[planar]] colorspaces are supported when using AviSynth 2.6 and corresponding MaskTools2.
<br>
<br>

== [[Script variables|Syntax and Parameters]] ==
:{{Template:FuncDef|pSharpen (clip clp, int "strength", int "threshold", float "ss_x", float "ss_y", int "dest_x", int "dest_y")}}
<br>
::{{Par2| |clip| }}
:::Input clip
<br>
::{{Par2|strength|int|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
<br>
::{{Par2|threshold|int|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
<br>
::{{Par2|ss_x|float|1.0}}
::{{Par2|ss_y|float|1.0}}
:::The horizontal and vertical [[supersampling]] factors, respectively. Higher values will reduce aliasing, at the expense of speed. 
<br>
::{{Par2|dest_x|int|clp.width()}}
::{{Par2|dest_y|int|clp.height()}}
:::Final image size; defaults to the dimensions of the input clip. 
<br>

== Examples ==
pSharpen with default settings:
 [[AviSource]]("Blah.avi")
 pSharpen(strength=25, threshold=75, ss_x=1.0, ss_y=1.0)
<br>
