Class MeanShiftPeak<T extends ImageGray>

java.lang.Object

boofcv.alg.feature.detect.peak.MeanShiftPeak<T>

public class MeanShiftPeak<T extends ImageGray>
extends java.lang.Object

Simple implementations of mean-shift intended to finding local peaks inside an intensity image. Implementations differ in how they weigh each point. In each iterations the mean of the square sample region centered around the target is computed and the center shifted so that location. It stops when change is less than a delta or the maximum number of iterations has been exceeded. If the image border is hit while searching the square will be push back until it is entirely contained inside the image.

Constructor Detail

MeanShiftPeak

public MeanShiftPeak(int maxIterations,
                     float convergenceTol,
                     WeightPixel_F32 weights,
                     java.lang.Class<T> imageType)

Configures search.

Parameters:

maxIterations - Maximum number of iterations. Try 10

convergenceTol - Convergence tolerance. Try 1e-3

weights - Used to compute the weight each pixel contributes to the mean. Try a uniform distribution.
