| ISubA |
Function
The ISubA function 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 image from another. If the second image is brighter, ISub does not reveal
anything, but
ISubA does (for example, .5 - .8 = -.3, absolute value of -.3 = .3).
