Abstract

Taking a sharp photo at several megapixel resolution tra- ditionally relies on high grade lenses. In this paper, we present an approach to alleviate image degradations caused by imperfect optics. We rely on a calibration step to en- code the optical aberrations in a space-variant point spread function and obtain a corrected image by non-stationary de- convolution. By including the Bayer array in our image for- mation model, we can perform demosaicing as part of the deconvolution.
