Zusammenfassung
Taking a sharp photo at several megapixel resolution traditionally
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 encode the optical aberrations in a space-variant point spread function and
obtain a corrected image by non-stationary deconvolution. By including the
Bayer array in our image formation model, we can perform demosaicing as part
of the deconvolution.
