All Implemented Interfaces:

IApplyInPlace

public class SobelCompassEdgeDetector
extends java.lang.Object
implements IApplyInPlace

Sobel Compass Edge Detector. The operator takes a single kernel mask and rotates it in 45 degree increments through all 8 compass directions: N, NW, W, SW, S, SE, E, and NE. The edge magnitude of the Sobel operator is calculated as the maximum magnitude across all directions. The edge magnitude is found by convolving each mask with the image and selecting the largest value at each pxel location. The edge direction at each point is defined by the direction of the edge mask that provides the maximum magnitude.
