Detailed Description

SoDespeckleProcessing engine

The SoDespeckleProcessing engine smooths an image replacing aberrant values by the mean value of their neighbors

For an introduction to image filters, see section Images Filters.

This engine smooths an image replacing aberrant values by the mean value of their neighbors. For each voxels of the input image, mean and standard deviation values of the rectangular neighbor's window are computed. The output image value is then given by:

Where is a user threshold factor on distance of current voxel gray level to the mean of its neighbors relatively to their standard deviation. The greater is, the stronger the blur is. This filter gives good results in case of impulse noise.
