BinarySmoothing3d

Transforms a binary three-dimensional image into another binary image with respect to the real local mean of each voxel neighborhood.

Access to parameter description

This algorithm computes a binary smoothing using a specified window size.
It consists of a two step procedure:

Computation of the local mean in the neighborhood, defined by the window size, considering foreground voxels with a value of 1 and background pixels with a value of 0.
Thresholding of the result using the threshold parameter.

Note: the binary smoothing does not preserve the topology of objects.
