For use in a video processing system that is capable of processing a video stream using a chain of video-processing algorithms, a system and method for performing automatic design and tuning in an efficient manner using hybrid heuristic optimization methods. In one aspect, the present invention is a method of tuning a video processing system including the steps of applying a genetic algorithm, monitoring the level of solution convergence, determining that the convergence level has satisfied a predetermined convergence-level criterion, and applying a second, more efficient search methodology when the convergence-level criterium has been satisfied to converge on the best local solution. This process is repeated until a best solution is found, and the video processing algorithms are adjusted accordingly. The video processing system iteratively converges toward control parameter configurations that produce a very high quality video image. In another aspect, the present invention is a processed signal produced according to this method. |
