Abstract:

This paper introduces an image filtering algorithm for degraded images based on automatic control techniques. The stability, observability, and controllability concepts from automatic control are formalized for evaluating image quality. The implementation of the developed algorithm is mainly
based on second order difference equation. The proposed scheme is applied to gray scale and color degraded images by Gaussian noise. We also give a comparison between the proposed scheme and lowpass filtering technique. The results indicate that our method gives good performance with smoothing the background noise while preserving the edges and the fine details with fewer bullrings, for gray scale and color images rather than the performance of  lowpass filter.

Keywords: control system, controllability Gaussian noise, image filtering, observability, stability
