Abstract

A method and an apparatus for deblurring an image from a sequence of images are described. The image comprises pixels. A motion estimation stage estimates motion of the pixels of the image. A point spread function modeling stage models point spread functions for the pixels of the image using the motion estimates. A deconvolution stage determines a deblurred estimate of the image using the modeled point spread functions. A feedback loop allows iteratively improving the motion estimates for the pixels until the modeled point spread functions converge.
