public class SplitContourAtSaddlePoints extends ObjectCollectionProviderUnary
Splits a 2D contour represented by an object-mask into several contours, splitting at "turn" points.

Specifically, smoothing spline interpolation is performed along the contour and splits occur at saddle points.

Each contour is represented by an input object.
