Constructor Detail

NaturalImageComparator

public NaturalImageComparator()

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

See Also:

NaturalImageComparator(double)

NaturalImageComparator

public NaturalImageComparator(double sensitivity)

Creates comparator with the specified sensitivity value

Parameters:

sensitivity - Maximum threshold for 3-D distance between colors in 3-D sRGB color space for pixels to be considered equal. Meaningful values are 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 the colors are completely different.
