Constructor Detail

HistogramDistance

public HistogramDistance(float[] targetImgNormHist)

Set the local reference to the normalized histogram of the target image; used during the distance compute.

Parameters:

targetImgNormHist - target image's normalized histogram

Method Detail

computeDistance

public float computeDistance(float intersection,
                             int bin)

called during the intersection process. Our distance compute is based on the difference between the target region's bin and the normalized target histogram's bin.

Specified by:

computeDistance in interface HistDistance

Parameters:

intersection - current intersection value

bin - current bin

Returns:

float return the updated distance value

init

public void init()

init the distance value

Specified by:

init in interface HistDistance
