Improved restoration algorithm of turbulence degraded images
A multi-frame blind deconvolution method is presented for the restoration of the astronomical object which has been degraded mainly by the turbulence and the identification of the point spread function. By using the improved generalized expectation-maximization on the base of the penalized maximum-likelihood estimation method, iterative algorithm is obtained to solve the above problems. Experimental results show that the method is effective and robust.
