Abstract : INVESTIGATIONS CONTINUED IN THE DEVELOPMENT OF PRACTICAL TECHNIQUES FOR REDUCING THE DATA-LINK CHANNEL CAPACITY REQUIRED FOR THE TRANSMISSION OF PICTORIAL DATA FROM SPACE VEHICLES TO THE GROUND. Classification studies concerned theAUTOMATIC EVALUATION OF THE MILITARY SIGNIFICANCE OF RECONNAISSANCE DATA AND RECOGNITION OF LAND AREAS WITH 90% or more cloud cover. Recognition logic involving the detection of parrel edge segments was simulated on 19 actual photographs which were chosen to challenge the logic severly; proper classification was achieved for every test image. The problem of processing the image data to reduce the channel capacity required for transmission was reviewed and analyzed. A fundamental study of general imageanalysis techniques was also performed. A possible integration is described of the dataclassification and image-coding subsystems into a general space-to-ground communication system. (Author)
