Space-variant image motion degradation and restoration

Abstract

A description of motion degradation in linear incoherent optical systems is presented. Given a mechanical description of the motion, an equivalent linear space-variant system containing all the motion effects is derived, and detailed examples of common types of variant and invariant motion are included. Following a review of restoration techniques for motion blur, a method for image restoration applicable to a large class of space-variant systems is presented. This method is based on the decomposition of the degradation into geometrical coordinate distortions and a space-invariant operation. A computer simulation of space-variant restoration is included.
