摘要
This paper describes a video quality analysis system for in-service monitoring of streamed videos, particularly over mobile/wireless networks. The algorithm adopts the no-reference method, and enables real-time measurement of video quality at any point in the content production and delivery chain using any given video. The technologies developed include no-reference methods for measuring picture freeze, picture loss, and blockiness. The developed system (where the software has not been optimized for speed) is able to process video of CIF size (352x288 pixels) at more than 30 fps on a Pentium-IV 3GHz computer. The experimental results show that the proposed video quality analysis system gives good accuracy for picture freeze, picture loss, and blocking detections.
