You might want to look at the nonuniform illumination demo in the Image Processing Toolbox.

Consider removing the halo/spotlight effect when taking a flash photo of a printed page where the paper is brown or gray. I've done this with a point and shoot 6mp canon with exposure set to -2 (to minimize the flash washing out the text), ISO 100, grayscale. Upsampling and converting to black and white as a post processing step would be nice. This can be approached as fixing illumination or 'background subtraction'.

Image registration but with more emphasis on nonlinear types of transformations. Hi Steve, I have a suggestion for a topic for one of your blogs.
