To improve the effect of adaptive optics images' restoration, we put forward a deconvolution algorithm improved by the EM algorithm which joints multiframe adaptive optics images based on expectation-maximization theory. Firstly, we need to make a mathematical model for the degenerate multiframe adaptive optics images. The function model is deduced for the points that spread with time based on phase error. The AO images are denoised using the image power spectral density and support constraint.doi:10.1155/2014/781607 fatcat:4gcqki3w6jcxjgx5gnhyoffvei
