A realistic model for visual communication systems
Don E. Pearson · Proceedings of the IEEE · 1967
In this paper Shannon's model of a communication system is extended to allow for the influence of the human viewer on the encoding and decoding processes. The extended model is shown to represent actual visual systems more realistically and to lead to the design of viewer-oriented codes which maximize the fidelity of transmission. Systematic procedures for the calculation of these codes are suggested, with practical examples.
