1. A computer implemented method for generating an industrial diagnostic comparison image, based on multiple baseline industrial diagnostic images, the method comprising: receiving a first baseline industrial diagnostic image into a computer readable medium; receiving a second baseline industrial diagnostic image into the computer readable medium; creating a comparison image from the first industrial diagnostic image and the second industrial diagnostic image, wherein the first baseline industrial diagnostic image provides a first color information for the comparison image and the second baseline industrial diagnostic image provides a second color information for the comparison image, such that pixels in the comparison image that correspond to pixels in the first baseline industrial diagnostic image exceeding an intensity of corresponding pixels in the second baseline industrial diagnostic image have a hue of the first color, and pixels in the comparison image that correspond to pixels in the second industrial diagnostic image exceeding an intensity of corresponding pixels in the first baseline industrial diagnostic image have a hue of the second color, and wherein the first color and the second color are different.
