ISubA
Function
This is identical to ISub, except
that it takes the absolute value of the result. This is to see if similar images
are different by subtracting one from another. If the second image is brighter,
ISub won't reveal anything, but ISubA will (ie, .5 - .8 = -.3,
absolute value of -.3 = .3).
