Constructor Detail

ImageCompareSA

public ImageCompareSA(float[][][] image1,
                      float[][][] image2,
                      int[] pixelBitDepth,
                      byte[][][] mask)
               throws WarningException

Constructor that does all the operations to compare images.

Parameters:

image1 - a 3D float array of image samples (index are [z][y][x])
