Paper Abstract

We introduce a simplified technique for calculating the maximum entropy solution for restoration of degraded images. We show that the maximum entropy solution can be formulated as an inverse filter estimate plus a correction term. The estimate starts with the inverse filter solution and an iterative algorithm produces the correction term. At each iteration we use an entropy gradient and an analytically calculated step size. The algorithm uses two Fourier transforms per iteration. Examples show that, after only a few iterations, the technique reduces the artifacts often found in the inverse filter estimate.
