PRACTICAL ALGORITHM FOR DIGITAL IMAGE RESTORATION.

A report is presented of some experimental results of a practical algorithm for the solution of digital image restoration problems. The solution is obtained directly from the system of linear equations which results from the discretization of the Fredholm integral equation of the first kind. this algorithm uses a simple regularized least squares technique. Also the regularization parameter for the optimum solution is calculated by a direct (non-iterative) method. A computer simulated example using both space-invariant and space-variant, spatially separable point spread functions, is presented.
