Class ImplEdgeNonMaxSuppression

java.lang.Object

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

public class ImplEdgeNonMaxSuppression
extends java.lang.Object

Algorithms for performing non-max suppression. Edge intensities are set to zero if adjacent pixels have a value greater than the current value. Adjacency is determined by the gradients discretized direction. NOTE: This is technically not true non-maximum suppression because equal values are allowed.

Method Detail

inner4

public static void inner4(boofcv.struct.image.GrayF32 intensity,
                          boofcv.struct.image.GrayS8 direction,
                          boofcv.struct.image.GrayF32 output)

Only processes the inner image. Ignoring the border.

naive4

public static void naive4(boofcv.struct.image.GrayF32 _intensity,
                          boofcv.struct.image.GrayS8 direction,
                          boofcv.struct.image.GrayF32 output)

Slow algorithm which processes the whole image.

border4

public static void border4(boofcv.struct.image.GrayF32 _intensity,
                           boofcv.struct.image.GrayS8 direction,
                           boofcv.struct.image.GrayF32 output)

Just processes the image border.

inner8

public static void inner8(boofcv.struct.image.GrayF32 intensity,
                          boofcv.struct.image.GrayS8 direction,
