Description

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

Requirements

• AviSynth+ r2347 or later

Syntax and Parameters

minvar (clip, int "sf", int "xgrid", int "ygrid", int "lx", int "ty", int "wd", int "ht", bool "uv", bool "a", bool "show")

clip   =

Input clip.

int  sf = 0

Frame number in which specified window is located.

int  xgrid = 5

Number of pixels along x axis in moving grid.

• Between 3 to 9

int  ygrid = xgrid

Number of pixels along y axis in moving grid.

• Between 3 to 9

int  lx = None. Must be specified

Window left x computing global variance.

• Within clip
• Less than rx

int  ty = None. Must be specified

Window top y for computing global variance.

• Within clip
• Less than by

int  wd = None. Must be specified

Window width for computing global variance.

• lx + wd be within frame

int  ht = None. Must be specified

Window height for computing global variance.

• ty + ht be within frame

bool  uv = true

Whether U and V of YUY2 and YUV formats to be processed.

• true for uv process, false for not process

bool  a = false

Whether A value of RGB formats to be processed.

• true yes, false no

bool  show = false

Whether variance values are to be displayed as an error message.

• true yes, false no

Examples

## This is some example code to remove noise from an image.
imagereader("C:\avi_plugins\varianslim\theoin.jpg", end = 10)
converttoyv16()
minvar(sf = 35,lx=220,wd=245,ty=322,ht=150, uv = true)
