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

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.

Ah, I'm sorry, I didn't read your comment properly. I thought the data was in format {{y11,y12,y13},{y21,y22},{},{y41,y42,y43}..., i.e. a list for each x-value which contains only the y-values at that location. Then you could have added Flatten to makeHist and everything else should have worked automatically. Can you maybe transform your data to that format?

@SparsePine: if it's always the first element, you could maybe index the set to drop that element data[[All,All,2;;]]?

@SparsePine: Without having tested this: I think all you have to do is adjust the makeHist function so it Flattens the data parameter before passing it to BinCounts

comment Is there an easy way to create a “IntensitySquaredCentroid” using ComponentMeasurements?
Why not just pass Image[ImageData[image]^3] to ComponentMeasurements?
