Class ImplEdgeNonMaxSuppression

java.lang.Object

boofcv.alg.feature.detect.edge.impl.ImplEdgeNonMaxSuppression

public class ImplEdgeNonMaxSuppression
extends Object

Algorithms for performing non-max suppression. Edge intensities are set to zero if adjacent pixels have a value equal to or greater than the current value. Adjacency is determined by the gradients discretized direction.
