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.

                                   throws ProvisionFailedException

Description copied from class: ObjectCollectionProviderUnary

Creates a ObjectCollection given the entity provided by the delegate.

Specified by:

createFromObjects in class ObjectCollectionProviderUnary

Parameters:

objects - the entity provided by the delegate.

Returns:

the created ObjectCollection that is returned by the provider.

Throws:

ProvisionFailedException - if the provider cannot complete successfully.
