[AviUtl]Non-local means Denoise filter with GPU acceleration

This is a powerful, yet not very difficult to use denoise filter. (using Non-local means algorithm)

Huge performance boost if you have a good graphics card. (P.S. beware of video chipset overheating for prolonged operation!)

■Original Codebase
AviUtl NL-Means filter by nodchip
http://kishibe.dyndns.tv/ (←missing file)

■Usage
Extract and Copy NL-Mean.auf into the .\Plugins folder of AviUtl.

・LuSpace(Luma-space)
・CoSpace(Color-difference space)
The area of pixels to be used in analysis.(spatial)
Recommend: 1-2

・LuTime
・CoTime
The area of pixels to be used in analysis.(temporal)
Recommend: 0-1

・LuVar
・CoVar
Somewhat analogous to “Strength”
A smaller value tends to leave noise untouched;
A large value tends to blur the image.
Default: 40

・Adapter
Desginate the GPU for handling the denoise process, when there are more than 1 GPU available.

・Protection
A large value tends to protect the low-frequency components.
Use 0 to skip low-freq. protection (Same as the old NL-Means)
Recommend: 40-60 for medium noise.

・Use UpdateSurface
Change the way for how data is transfered from system memory to video memory.
Processing speed may vary by this setting(which one is faster depends on individual PC)

When CoSpace and CoTime are set to 0, analysis on color-difference will be skipped and become faster.

■Requirement
・SSE2 capable CPU
・Microsoft Visual C++ 2010 SP1Redistribution Package

・Video card/chipset supports Video Shader (Pixel shader) 3.0
