A spatial and spectral combined image restoration approach

In this paper, an image restoration framework is presented, by using two available observations of specific spatial and spectral resolutions. The proposed approach employs an Expectation-Maximization (EM) algorithm based multi-band image restoration scheme, in which both observation models are used for restoration. Experimental results illustrate that the proposed restoration approach is capable of producing improved restored results, compared to existing restoration approaches, in which only one observation model is utilized while the other observation is treated as auxiliary.
