Restoration of turbulence degraded images using improved multi-frame blind deconvolution algorithm
Bin Li, Zhiguo Cao, Nong Sang, T. Zhang · Electronics Letters · 2004
For the restoration of astronomical objects which are degraded mainly by turbulence, an improved multi-frame blind deconvolution method using the generalised expectation-maximisation (GEM) on the basis of the penalised maximum-likelihood estimation method is presented. Experimental results indicate that this method has better performance and costs less time.
