Introduction

a WarpSharpenning filter for Avisynth 2.5

Requirements

• YV12
• ISSE compatible CPU.

Parameters

aWarpSharp(float "depth", int "blurlevel", float "thresh", int "cm", int "bm", bool "show")

depth float = 16.0

range: 0.0 - 64.0

blurlevel int = 2

range: 1 - 4

These are the only settings you need to tweak to achieve any effect.

Blurlevel consumes CPU power, but gives a big boost to the warpsharpenning.

thresh float = 0.5

range: 0.0 - 1.0

A float value of 1.0 means 100% (max). It's the bump mapping saturation setting.

Default value is recommended for maximum quality.

If you tweak this setting, keep in mind it will enhance inequality of warping between edges.

cm int = 2

chroma mode:

• 0 : disables chroma filtering
• 1 : enables chroma warping with luma bump map (recommended)
• 2 : enables chroma independent warping & bump map
• 3 : chroma -> luma
• 4 : chroma -> chroma

bm int = 2

blur modes:

• 0 : hq 3-pass
• 1 : fast 3-pass
• 2 : fast 1-pass
• 3 : light blur

show bool = false

If true, it will show an edge mask. Useful for adjusting depth, blurlevel, and thresh.
