public class CannyEdgeDetectorAlgorithm
extends JIPipeSimpleIteratingAlgorithm

This is the JIPipe version of the ImageJ plugin ...

This is a plugin version of Tom Gibara's implementation of the Canny edge detection algorithm in Java, available at:

http://www.tomgibara.com/computer-vision/canny-edge-detector

This software has been released into the public domain. Please read the notes in this source file for additional information.

This class provides a configurable implementation of the Canny edge detection algorithm. This classic algorithm has a number of shortcomings, but remains an effective tool in many scenarios. This class is designed for single threaded use only.

For a more complete understanding of this edge detector's parameters consult an explanation of the algorithm.
