Please note that
this illustration represents the Two-way Image Comparison
For each original image, you can see the difference with
respect to the other sources.
Change the image difference algorithm to use to display
the difference, change the image alignment with respect to
other images, strech images.
The toolbar controls let you change the thresholds for
equivalent/different pixels, strech images, and zoom
The status bar contains metrics about the displayed images
(size, PSNR, MSE)
