SYSTEM AND METHOD FOR PROVIDING A SCALABLE DYNAMIC OBJECTIVE METRIC FOR AUTOMATIC VIDEO QUALITY EVALUATION

摘要

There is disclosed an improved system (100) and method for providing a scalable dynamic objective metric for automatically evaluating the video quality of a video image. The system (100) comprises an objective metric controller (150) that is capable of receiving a plurality of objective metric model units (120, 130, 140). The system determines a scalable dynamic objective metric from a weighed average of the plurality of objective metric figures of merit. The scalable dynamic objective metric represents the best correlation of objective metric measurements of the video image with subjective measurements of the video image. The weight value of individual objective metric figures of merit may be increased or decreased depending upon the type of video image being evaluated. Individual objective metric figures of merit may be added to the system (100) or deleted from the system (100). The system is capable of continually determining a new value of the scalable dynamic objective metric as the plurality of objective metric model units receive new video images.
