Constructor Detail

AverageDistanceImageComparator

public AverageDistanceImageComparator()

Creates comparator with the default sensitivity value = 0.02 (around 5 in 0-255 color component value).

AverageDistanceImageComparator(double)

AverageDistanceImageComparator

public AverageDistanceImageComparator(double sensitivity)

Creates comparator with the specified sensitivity value

Parameters:

sensitivity - Maximum threshold for average 3-D distance between colors in 3-D sRGB color space for images to be considered equal. Meaningful values lay between 0 and approx 1.733. 0 means colors should be equal to pass the comparison, 1.733 (which is more than square root of 3) means that comparison will be passed even if all the colors are completely different.
