Abstract
An interactive process is described for fine tuning a specific algorithm for use in a real time video bandwidth compression system. Parameters for the algorithm are initially optimized using computer simulation, then implemented in hardware to observe performance. The next step is the modification of the parameters to improve the real time performance of the system. This paper describes some of the algorithm parameter choices that were made in the implementation of a two-dimensional discrete cosine transform processor for the Air Force Wright Aeronautical Laboratory. Examples are shown of alternate choices for DCT scaling strategies, filter functions, and bit assignment procedures. The impact of these parameter selections on the resulting imagery is included using both simulation and hardware outputs.
