Simultaneous estimation of PSF and global frame shifts at lower S/N ratios

We present new algorithm for simultaneous estimation of degradation PSF and global frame shifts, using degraded frames only. Algorithm is based on the singular value decomposition (SVD). Separable approximation is supposed for the point spread function (PSF). It has been shown that frame shifts caus...
