Contains several functions for propagating chamfer distances (approximation of euclidean distances) within binary images.
Contains also some functions for computing geodesic distances between two points, or for computing geodesic parameters (geodesic diameter, geodesic radius...) of labelled particles.
For the visualisation of distance maps, I suggest my other contribution "double2rgb", also on FEx.
add support for 3D geodesic distance transform, and for 5-by-5 2D chamfer masks
