comment Ellipse counting from image
@RahulNarain: Yes, you're right of course. I was thinking of the absolute value, which is not differentiable at the origin, but it's square is. But, as you said, that's not true for the distance transform. I'll delete that paragraph from the answer.

Or, if you don't want pass x to f, you could use currying: declare a global function makeF that takes a parameter x and returns a new function f. Then use f=makeF[x]; inside the module where you want to use f.

@VitaliyKaurov: Basically, the function I'm looking for is to ImageTransformation what ListPlot is to Plot: Does the same thing, but with an array of data instead of a function to generate the data.
