The Extraction Of Latent Information From Photographs
A. F. Lehar · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1984
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.© (1984) COPYRIGHT SPIE--The International Society for Optical Engineering.
