Abstract

In this paper, we propose a scheme for blind image restoration based on the convex combination of a blind equalizer with a decision-directed equalizer. The combination is also adapted in a blind manner, which allows the automatic switching between the component filters. Thus, the proposed scheme is able to achieve the performance of a technique based on a supervised adaptive filtering with no previous knowledge about the undegraded image. Simulations illustrate the performance of the propose scheme with respect to existing image deconvolution techniques based on blind equalization algorithms.
