DeNoise

Revision as of 14:24, 31 May 2015

Description

Using Variance of a given window, minimizes noise and tries to preserve edges and a full description is at click me.

Requirements

• AviSynth 2.5.8 or 2.6.0 or greater
• Supported color formats: RGB24, RGB32, YUY2, YV12, *YV16, *YV24, *YV411, *Y8

* Not available in AviSynth 2.5.8.

Syntax and Parameters

DeNoise (clip, int "sf", int "ef", int "xgrid", int "ygrid", bool "getvar", bool "clip", int "lx", int "ty",, int "rx", int "by", int "elx",int "ety",int "erx",int "eby",int "var",int "evar", bool "uv", bool "usey", bool "show")

clip   =

Input clip.

sf  int = 0

process starts on frame .

ef  int = last frame

process ends on frame .

xgrid  int = 5

local grid size in x direction .

ygrid  int = xgrid

local grid size along y.

getvar  bool = true

Is variance to be determined from a window?

clip  bool = a

Is variance from first frame window is valid for entire clip? true. If false to be determined frame by frame.

lx  int = must be specified if getvar is true

left x coord of window on 1st frame.

ty  int = must be specified if getvar is true

top y coordinate of window on 1st frame.

rx  int = must be specified if getvar is true

right x coord of window on 1st frame.

by  int = must be specified if getvar is true

bottom y coordinate of window on 1st frame.

elx  int = lx

left x coord of window on last frame.

ety  int = ty

top y coordinate of window on last frame.

erx  int = rx

right x coord of window on last frame.

eby  int = by

bottom y coordinate of window on last frame.

var  int = 100

value to be used as global variance. Will be used if getvar is false.

evar  int = var

variance on last frame. In between linear interpolation.

uv  bool = true

Whether u v planes to be processed(for planar and yuy2 input)?.

usey  bool = false

can variance of y plane can be used for u v planes?

show  bool = false

if true an error message showing variance values determined will appear)

Examples

## This is some example code to remove noise from an image.
imagereader("C:\avi_plugins\varianslim\theoin.jpg", end = 10)
converttoyv16()
DeNoise(clip=false,lx=220,rx=245,ty=322,by=402, uv = true, show = false)
