Method Detail

correlation

double correlation(Histogram thisHistogram,
                   int displacement,
                   Histogram otherHistogram)

The implementation of a histogram correlation or distance measure.

Parameters:

thisHistogram - the first histogram

displacement - the value to displace the otherHistogram (e.g. for optimal correlation, minimum distance between the two)

otherHistogram - the second (not displaced) histogram

Returns:

the correlation between a histogram and a displaced histogram
