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.ImageMultiBand>

Parameters:

image - Input image

getImageType

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

Specified by:

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

findPeak

protected void findPeak(float cx,
            float cy,
            float[] meanColor)

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

Parameters:

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

meanColor

protected static void meanColor(float[] sum,
             float[] mean,
             float total)

sumColor

protected static void sumColor(float[] sum,
            float[] pixel,
            float weight)

savePeakColor

protected void savePeakColor(float[] a)
