SO - Surface extraction

(03/7/00)

PURPOSE

Finds pixels/voxels which are on a specified surface threshold level. Pixels/voxels having a value greater or equal to the specifed threshold which are adjacent to pixels/voxels having values that are below the threshold are assigned an output value of 1.0. Pixels not on the surface are assigned output value of 0.0. Works for both 2D and 3D.   Example.
