Method Summary

double	correlation(Histogram thisHistogram, int displacement, Histogram otherHistogram) The implementation of a histogram correlation or distance measure.
void	plotCorrelation(Histogram thisHistogram, int displacement, Histogram otherHistogram, java.lang.String fileName, java.lang.String title) Plots two histograms and the intersection between the two.

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

plotCorrelation

void plotCorrelation(Histogram thisHistogram,
                     int displacement,
                     Histogram otherHistogram,
                     java.lang.String fileName,
                     java.lang.String title)

Plots two histograms and the intersection between the two.

Parameters:

thisHistogram - the first histogram

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

otherHistogram - the second (not displaced) histogram

fileName - Where to save the plot.

title - The title of the plot.
