                                  boolean fast)

Method Detail

process

public void process(T image)

Performs mean-shift clustering on the input image

Specified by:

process in class SegmentMeanShiftSearch<T extends boofcv.struct.image.ImageGray>

Parameters:

image - Input image

getImageType

public boofcv.struct.image.ImageType<T> getImageType()

Specified by:

getImageType in class SegmentMeanShiftSearch<T extends boofcv.struct.image.ImageGray>

findPeak

protected void findPeak(float cx,
                        float cy,
                        float gray)

Uses mean-shift to find the peak. Returns the peak as an index in the image data array.

Parameters:

gray - The color value which mean-shift is trying to find a region which minimises it
