Paper Abstract

Optics is necessary to analyze and realize imaging processes, but it is also a possible tool in image processing. Since the concepts of coherent and incoherent optical image processing including the formalism of spacial frequency filtering, the laser, and holography, were developed, computer science went through revolutionary developments. The past and present situation of optical image processing is critically examined, and three subject to which we have recently contributed are used as illustrations. The first is the use of interference phenomena as spatial frequency filters, which can be a useful complement to the more conventional use of diffraction. The second is the use of white light illumination in spatial frequency filtering setups to obtain spatial frequency pseudocoloring. Finally, a texture discrimination experiment involving optical preprocessing by a set of interference spatial frequency filters Followed by computer classification is described.
