Median

Applies a median filter to the image. This can be useful for removing noise.

user

Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.

out

The output image generated by this node.

enabled

Turns the node on and off.

radius

The size of the filter in pixels. This can be varied independently in the x and y directions.

boundingMode

The method used when the filter references pixels outside the input data window.

expandDataWindow

Expands the data window to include the external pixels which the filter radius covers.

masterChannel

If specified, this channel will be used to compute the pixel index to select for all channels. You would probably want to use this with a channel that represents the overall luminance of the image. It will produce a rank filter which is lower quality, but preserves additivity between channels, and is a bit faster.
