Abstract

A digital image processing system is described, which has been assembled for the routine diagnosis and correction of a wide variety of photographic problems encountered in police work. The major hardware components of this system are outlined, and then a range of useful enhancement and restoration techniques are described showing examples. These methods range from simple contrast manipulations to complicated restoration processes involving 2 dimensional large format deconvolutions.
