"Existing multichannel blind restoration techniques are prone to noise, assume perfect spatial alignment of channels and a correct estimation of blur size. We develop an alternating minimization scheme based on maximum a posteriori probability estimation with a priori distributions derived from the multichannel framework and from the variational priciple. We observe that the exact knowledge of the blur size is not necessary and that translation misregistration can be automatically removed."@en . .
