Description
This is an adaptive local noise reduction filter. It uses global variance of the noise, local mean and local variance in a moving grid of specified size. It tries to preserve edges as closely as possible. Full Description
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.
- clip =
- int sf = 0
- Frame number in which specified window is located.
- int sf = 0
- int xgrid = 5
- Number of pixels along x axis in moving grid.
- Between 3 to 9
- Number of pixels along x axis in moving grid.
- int xgrid = 5
- int ygrid = xgrid
- Number of pixels along y axis in moving grid.
- Between 3 to 9
- Number of pixels along y axis in moving grid.
- int ygrid = xgrid
- int lx = None. Must be specified
- Window left x computing global variance.
- Within clip
- Less than rx
- Window left x computing global variance.
- int lx = None. Must be specified
- int ty = None. Must be specified
- Window top y for computing global variance.
- Within clip
- Less than by
- Window top y for computing global variance.
- int ty = None. Must be specified
- int wd = None. Must be specified
- Window width for computing global variance.
- lx + wd be within frame
- Window width for computing global variance.
- int wd = None. Must be specified
- int ht = None. Must be specified
- Window height for computing global variance.
- ty + ht be within frame
- Window height for computing global variance.
- int ht = None. Must be specified
- bool uv = true
- Whether U and V of YUY2 and YUV formats to be processed.
- true = uv process
- false = do not process uv
- Whether U and V of YUY2 and YUV formats to be processed.
- bool uv = true
- bool a = false
- Whether A value of RGB formats to be processed.
- true = yes
- false = no
- Whether A value of RGB formats to be processed.
- bool a = false
- bool show = false
- Whether variance values are to be displayed as an error message.
- true = yes
- false = no
- Whether variance values are to be displayed as an error message.
- bool show = false
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)
