I work at a small mechanical engineering company, where I develop software and image processing algorithms for camera-based inspection machines.

You could pass x to f as a parameter.

comment How can I efficiently “remap” an image?
@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.

comment Measure length and diameter of objects in an image
CaliperLength and CaliperWidth give the width/height of the smallest (possibly rotated) bounding rectangle, IIRC.

comment Measure perimeter of black edge in Mathematica
@s.s.o: Yes, the white pixels are extended over the borders. But borderPixels checks if a pixels is white in the dilated image and black in the original. So I don't have to worry about pixels that aren't black in the original image.

comment Image Processing Mag and Phase Spectrum of Sobel, Roberts Mask
@user8727: Not trying to be rude, but you should really get an introductory book about MMA and read it cover to cover. Having to ask basic stuff like "how do I multiply two things" must be annoying for you too, and the resulting answers aren't helpful to anyone else. That's why your questions get closed or downvoted: A Q&A-site like this can't replace a good tutorial, introductory course or book. It's simply the wrong format. I can recommend "Programming in MMA" by Maeder and "Programming with MMA" by Wellin.

I'm not quite sure I know what you meant, so I've updated the answer, and it seems to work fine.
