                          Histogram second)

Description copied from interface: HistogramCorrelation

The implementation of a histogram correlation or distance measure.

Specified by:

correlation in interface HistogramCorrelation

Parameters:

first - the first histogram

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

second - the second (not displaced) histogram

Returns:

the correlation between a histogram and a displaced histogram
