public class AlgorithmHistogram2Dim
extends AlgorithmBase

This algorithm creates a two dimensional histogram of the data in 2 black and white images or 1 color image. if doLinearRescale is true, the range of data in the second image is rescaled to be the same as the range of data in the first image. That is the second image minimum is rescaled to the first image minimum and the second image maximum is rescaled to the first image maximum. Also, if linear rescaling is used the number of bins in the second image is set equal to the number of bins in the first image. The default number of bins equals the min(256,maximum value - minimum value + 1) if the data is not float or double. If the data is float or double, the default number of bins is 256. ch1 = 0 to ch1 = bin1 - 2 all have a width of (bin1 - 1)/range1, but ch1 = bin1 - 1 has no width, it is a single value at max1. bin ch1 = 0 covers min1 <= ch1 < min1 + (max1 - min1)/(bin1 - 1) bin ch1 = 1 covers min1 + (max1 - min1)/(bin1 - 1) <= ch1 < min1 + 2*(max1 - min1)/(bin1 - 1) bin ch1 = bin1 - 2 covers min1 + (bin1 - 2)*(max - min1)/(bin1 - 1) <= ch1 < max1 bin ch1 = bin1 - 1 covers only max1 The processing for maximum values is specially handled to prevent loss of top bin counts from rounding errors.
