I have a *.jpeg image of a x-y scatter plot (not monotonic), and I would like to extract the data points. Any ideas? I was going to do it manually by pixels, but I figured that there is a good way to do that with linear algebra.

The File Exchange program GRABIT is a good way to extract data points from an image of a graph. Download it here: http://www.mathworks.com/matlabcentral/fileexchange/7173

FFT function ?!?!? Do you know what the FFT is?
I suppose you could use image analysis (thresholding, labeling, regionprops) if your points were well isolated and you had already cropped the axes, tick marks, etc. out of your image. I second Ashish's suggestion.
