Image Enhancement via Extrapolation Techniques: A Two Dimensional Iterative Scheme a Direct Matrix Inversion Scheme

In [1] and [2], we have developed a model and three dimensional inversion algorithm for detecting flaw in structures. The model, based on rigorous electromagnetic theory, and the algorithm have as their main objective the high resolution imaging of the flaw. The algorithm is computationally intensive and, like other inversion techniques, involves the solution of some ill conditioned problems
