Description

TempLinearApproximate takes several frames and for each pixel calculates linear approximation of its values through time, then returns its value in the middle (unless close to beginning or end of clip) of that line. Meant mainly for denoising aid in motion compensated clips. If you use it on plain video - you'll just get heavy ghosting.

Requirements

• [x86]: AviSynth+ or AviSynth 2.6
• Supported color formats: Y8, YV12, YV16, YV24

Syntax and Parameters

TempLinearApproximate (clip, int "radius", int "plane", bool "inLsb", bool "outLsb")

clip   =

Input clip.

int  radius = 5

The size of neighborhood of the current frame. Approximation is made by (radius * 2 + 1) points, unless close to beginning or end - it is trimmed in these cases.

int  plane = 7

The sum of three flags of planes to process. 1=Y, 2=U, 4=V. By default all planes are processed.

bool  inLsb = false

Set to true if input clip is in Stack16 bit format.

bool  outLsb = false

Set to true if you want output to be in Stack16 bit format, whether input clip is Stack16 bit or not.

Examples

TempLinearApproximate with default settings:

AviSource("blah.avi")
TempLinearApproximate(radius=5, plane=7, inLsb=false, outLsb=false)

Stacked 16-bit processing with AviSynth+:

AviSource("blah.avi")
ConvertToStacked()
TempLinearApproximate(radius=5, plane=7, inLsb=true, outLsb=true)
ConvertFromStacked()
