ClosestBoundaryPoints3d

Computes the Chamfer distance map of the background of a three-dimensional image and the coordinates of the associated boundary points.

Access to parameter description

This algorithm is like the DistanceMap3d algorithm, applied on the background of the input image, and indicates the distance to the closest object boundary point.
It also stores the X, Y, and Z coordinates of the corresponding point in three additional output images.

Note: This algorithm does not take into account the input image calibration. The output values are systematically indicating distance in voxel units.
