Description
Using Variance of a given window, minimizes noise and tries to preserve edges and a full description is at click me.
Requirements
- 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 =
- sf int = 0
- process starts on frame .
- sf int = 0
- ef int = last frame
- process ends on frame .
- ef int = last frame
- xgrid int = 5
- local grid size in x direction .
- xgrid int = 5
- ygrid int = xgrid
- local grid size along y.
- ygrid int = xgrid
- getvar bool = true
- Is variance to be determined from a window?
- getvar bool = true
- clip bool = a
- Is variance from first frame window is valid for entire clip? true. If false to be determined frame by frame.
- clip bool = a
- lx int = must be specified if getvar is true
- left x coord of window on 1st frame.
- lx int = must be specified if getvar is true
- ty int = must be specified if getvar is true
- top y coordinate of window on 1st frame.
- ty int = must be specified if getvar is true
- rx int = must be specified if getvar is true
- right x coord of window on 1st frame.
- rx int = must be specified if getvar is true
- by int = must be specified if getvar is true
- bottom y coordinate of window on 1st frame.
- by int = must be specified if getvar is true
- elx int = lx
- left x coord of window on last frame.
- elx int = lx
- ety int = ty
- top y coordinate of window on last frame.
- ety int = ty
- erx int = rx
- right x coord of window on last frame.
- erx int = rx
- eby int = by
- bottom y coordinate of window on last frame.
- eby int = by
- var int = 100
- value to be used as global variance. Will be used if getvar is false.
- var int = 100
- evar int = var
- variance on last frame. In between linear interpolation.
- evar int = var
- uv bool = true
- Whether u v planes to be processed(for planar and yuy2 input)?.
- uv bool = true
- usey bool = false
- can variance of y plane can be used for u v planes?
- usey bool = false
- show bool = false
- if true an error message showing variance values determined will appear)
- show bool = false
Examples
## This is some example code to remove noise from an image.
imagereader("C:\avi_plugins\varianslim\theoin.jpg", end = 10)
converttoyv16()
minvar(clip=false,lx=220,rx=245,ty=322,by=402, uv = true, show = false)
