Package inra.ijpb.morphology.strel Description

A collection of Structuring Element ("Strel") implementations for mathematical morphology.

Contains the implementation of several types of structuring elements. The packages tries to takes advantage of the separability property of most structuring elements.

The package can be divided into:

• Specialization Strel interfaces: SeparableStrel, InPlaceStrel
• Abstract classes for facilitating implementations: AbstractStrel, AbstractSeparableStrel, AbstractInPlaceStrel
• Final Strel implementations: SquareStrel, OctagonStrel, DiamondStrel, Cross3x3Strel...
• Utility classes that manage local extremum: LocalExtremum, LocalExtremumBufferGray8, LocalExtremumBufferDouble
