Abstract
A two-dimensional blur kernel is computed for a digital image by first estimating a sharp image from the digital image. The sharp image is derived from the digital image by sharpening at least portions of the digital image. The two-dimensional blur function is computed by minimizing an optimization algorithm that estimates the blur function.
