System and method for optimizing control parameter settings in a chain of video processing algorithms

摘要

By using a chain of video processing algorithms, and the systems and methods disclosed for use in a video processing system capable of processing a video stream, the system and method, each of the video in the chain of the video processing algorithms to provide a high quality video image constitute a control parameter set of the processing algorithm at the best. Video processing algorithms of the present invention comprises a chain, the optimization unit and a target quality metric units of video processing algorithms. The output video stream in the chain of from the video processing unit is fed back to the target quality metric units. Target quality metric units by calculating a suitability value, and provides a fitness value to the optimization unit. Fit unit using a goodness of fit value to configuration control parameters of the set of video processing algorithms. One advantage to the embodiment of the invention, optimization unit uses a genetic algorithm to optimize processing. Video processing system so as to iteratively converge to the control parameter structure for generating a high-quality video image.
