Description
Purely spatial denoising function that includes 24 different modes. mode 13 through 16 are meant for deinterlacing only, they required interlaced content.
Requirements
- Progressive input only (except for mode 13 through 16)
- Supported color formats: Y8, YV12, YV16, YV24, YV411
Syntax and Parameters
- RemoveGrain (clip, int "mode", int "modeU", int "modeV", bool "planar")
- clip =
- Input clip must be planar
- clip =
- int mode = 2
- int modeU = mode
- int modeV = modeU
- Independently control the processing mode for each plane.
- Each mode applies a different kind of smoothing to the input clip by combining each pixel with 8 of its neighbours.
- Just like original RemoveGrain, the borders rows and columns (1-pixel thick) are not processed.
- int mode = 2
- -1 : Bypass - input plane is trashed thus faster than mode 1
- 0 : Copy - input plane is left intact
- 1 : Clips the pixel with the minimum and maximum of the 8 neighbour pixels.
- 2 : Clips the pixel with the second minimum and maximum of the 8 neighbour pixels. [Default]
- 3 : Clips the pixel with the third minimum and maximum of the 8 neighbour pixels.
- 4 : Clips the pixel with the fourth minimum and maximum of the 8 neighbour pixels, which is equivalent to a median filter.
- 5 : Line-sensitive clipping giving the minimal change.
- 6 : Line-sensitive clipping, intermediate.
- 7 : Line-sensitive clipping, intermediate.
- 8 : Line-sensitive clipping, intermediate.
- 9 : Line-sensitive clipping on a line where the neighbours pixels are the closest.
- 10 : Replaces the target pixel with the closest neighbour.
- 11 : [1 2 1] horizontal and vertical kernel blur. Similar to Blur(1).
- 12 : Same as mode 11.
- 13 : Bob mode, interpolates top field from the line where the neighbour pixels are the closest.
- 14 : Bob mode, interpolates bottom field from the line where the neighbour pixels are the closest.
- 15 : Bob mode, interpolates top field. Same as 13 but with a more complicated interpolation formula.
- 16 : Bob mode, interpolates bottom field. Same as 14 but with a more complicated interpolation formula.
- 17 : Clips the pixel with the minimum and maximum of respectively the maximum and minimum of each pair of opposite neighbor pixels.
- 18 : Line-sensitive clipping using opposite neighbours whose greatest distance from the current pixel is minimal.
- 19 : Replaces the pixel with the average of its 8 neighbours.
- 20 : Averages the 9 pixels ([1 1 1] horizontal and vertical blur). Similar to Blur(1.58).
- 21 : Clips pixels using the averages of opposite neighbour.
- 22 : Same as mode 21 but simpler and faster.
- 23 : Small edge and halo removal, but reputed useless.
- 24 : Small edge and halo removal, but reputed useless.
- By default if modeU is not set it defaults to the value of mode. If modeV is not set it defaults to the value of modeU
- bool planar = false
- Parameter to keep compatibility with the original plugin; it's use is not recommended.
- This allows to skip any colorspace checks whatsoever, making the filter always assume that planar input is passed.
- bool planar = false
Examples
RemoveGrain with default values:
AviSource("Blah.avi") RemoveGrain(mode=2, modeU=2, modeV=2, planar=false)
