Paper Abstract

In this paper, the problem of restoration of multiple misregistered, blurred and noisy images is considered. Motivation for this problem comes from the larger problem of construction of a high resolution restored image from the observed set of low-resolution images. The global approach is to decompose the problem into a sequence of sub-problems, namely registration, restoration and interpolation. The restoration problem is addressed here. For simultaneous restoration of the observed images, a parametric stochastic model for the image correlations is derived and used to obtain a linear minimum mean square error (LMMSE) estimate of the original image at each sensor. The resulting restored low-resolution images are integrated to construct a single restored high resolution image. Simulation results are presented to illustrate the performance of the proposed restoration scheme.
