摘要
A new 3D parallel thinning algorithm for medial surfaces is proposed. It works in cubic grids with the 6-connectivity. This algorithm is based on a precise definition of end points which are points belonging to surfaces or curves. We give a necessary and sufficient Boolean condition for characterizing points which are simple, non-ends and which are border points of a certain type (N, S, E, W, U, D). The algorithm consists precisely in removing all points satisfying the condition: it has a little computational cost and it is based on a clear thinning criterion.
