Abstract

A technique for performing image processing in real time on normally illuminated scenes--and its potential applications to underwater search and visibility improvement--are described. The Cybercon, a system embodying this technique, is currently undergoing terrestrial tests for the U. S. Army. The system consists of an electro-optical sensor under programmed electronic control. Image processing is performed in a special camera tube. Results are visible to the operator at the phosphor viewing screen of the unit, or may be transmitted to a remote display. Tests on simulated backscatter penetration have been performed, and are illustrated in the paper. This is accomplished by high-pass filtering of the visual image. A 2:1 increase in visibility range is estimated. For underwater search applications, the Cybercon sensor may be programmed to detect the particular shape or spectral characteristic desired. An example of this type of shape detection performed on underwater photography is presented. Automatic monitoring for motion or changes within the scene, together with visibility improvement, can be performed by this sensor used as a processor. Terrestrial examples of this type of application are presented.
