Description

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

Requirements


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)
