Despeckle Node.

The Despeckle node is used to smooth areas of an image in which noise is noticeable, while leaving complex areas untouched.

This works by the standard deviation of each pixel and its neighbors is calculated to determine if the area is one of high complexity or low complexity. If the complexity is lower than the threshold then the area is smoothed using a simple mean filter.

Inputs

Factor

Controls the amount the filter effects the image.

Image

Standard image input.

Properties

Threshold

The threshold to control high/low complexity.

Neighbor

The threshold to control the number of pixels that must match.

Outputs

Image

Standard image output.
