gov.nih.mipav.model.algorithms.AlgorithmEmbeddedConfidenceEdgeDetection

All Implemented Interfaces:

ActionListener, WindowListener, Runnable, EventListener

public class AlgorithmEmbeddedConfidenceEdgeDetection
extends AlgorithmBase

The java code is ported from C++ code downloaded from http://coewww.rutgers.edu/riul/research/code.html. The relevant web page section says: Edge Detection and Image SegmentatiON (EDISON) System C++ code, can be used through a graphical interface or command line. The system is described in Synergism in low level vision. For comments, please contact Bogdan Georgescu or Chris M. Christoudias. The EDISON system contains the image segmentation/edge preserving filtering algorithm described in the paper Mean shift: A robust approach toward feature space analysis and the edge detection algorithm described in the paper Edge detection with embedded confidence. This code was ported by William Gandler. References ------------------------------------------------------------------------------------------------- [1] D. Comanicu, P.
