Abstract
The finite aperture of any physical imaging system eliminates the high spatial-frequency components of the object from appearing in the image. The lack of high frequency detail results in a loss of resolution in the observed image. It has been shown that, for an object of finite extent, an exact restoration of the object from a DL image is possible. However, numerical implementation of the DL image restoration process is highly unstable in the presence of measurement noise. In the dual of the image restoration problem, the extrapolation of a finite segment of the DL (i.e. spatially limited) image data in the presence of measurement noise is performed. It has been found that the imposition of a priori constraints, such as a non-negativity of the estimate, will stabilize the restoration process. In this paper, we employ optimal data fitting techniques that uses linear programming (LP) for optimization. Results of numerical experiments are presented to illustrate the efficacy of this approach.
