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).
