This book was released on 1972 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The desire to transmit high-quality, single-frame images such as reconnaissance photographs places a severe strain on narrow-band communications channels. The problem is severe enough to warrant use of complex and expensive compression methods, providing they really work. The authors propose a method of evaluating compression algorithms applied to pictures, and apply it to several well-known techniques already having one or more hardware implementations. The importance of proper data management for pictorial communication is illustrated, and by implication are shown to be much more important than the data compression algorithms. Relevant to the data management proposals, some methods of improving the cosmetic quality of sparsely sampled images are shown. An interactive computer system (AFCRL's Image Analysis Facility) was used in the study. Special features of this facility are operator control of the entire process from image acquisition through final display, interactive processing, and the ready ability to explore new ideas in some depth.
