Paper Abstract

The current interest in applying hybrid techniques to data extraction from film is discussed and reviewed. The three basic operations of power spectral analysis, spatial filtering, and correlation are described. Particular emphasis is placed on how these operations can be carried out with an appropriate combination of optical with either digital (binary) or electronic (analogue) subsystems. Some examples will illustrate the procedure.
