Bilateral

Inputs: Source, Guide (optional), mask (optional).

Setting	Default	Range or choices	What it does
Use GPU if available	on		Kept from Nuke scripts; the filter always runs on the CPU for now.
channels	all	rgba, rgb, alpha, all	The channels the node changes; the others pass through.
Guide Channels	all		Kept from Nuke scripts; the colour differences are read from the Guide input's R, G and B (else the source's).
Size	3	0 to 20	The neighbourhood's radius in pixels, horizontally; the filter uses the average of x and y.
Size	3	0 to 20	The neighbourhood's radius in pixels, vertically; the filter uses the average of x and y.
Positional Sigma	0.4	0 to 1	How fast a neighbour's weight falls with distance, as a fraction of the size.
Color Sigma	0.4	0 to 1	How fast a neighbour's weight falls with its colour difference from the pixel; smaller keeps edges sharper.
Filter	gaussian	gaussian, median	How pixels are resampled when the picture moves or scales.
