Abstract

In recent years much effort has been devoted to the problem of restoring signals that have been convolutionally degraded, perhaps by a process that can be modeled by a linear system. Typical degraded signals may be one or two-dimensional, such as a resonated audio signal or a blurred photograph. Most approaches to the restoration problem, however, have assumed in advance a knowledge of the degrading system, and have centered around workable methods of restoration. Recent research at Utah has led to the development of a non-linear homomorphic restoration system needing very little a priori information about the system that produced the convolutional degradation.
