IN-service video quality monitoring
A video quality monitoring system for in-service monitoring of videos is described in this paper. The technologies developed include a no-reference method for blockiness measurement that exploits the characteristics of human visual system using the concept of just-noticeable-difference. This approach works even for scenario where the blockiness is not at known fixed locations. To provide a complete over-view of the integrated video quality monitoring system, methodologies for measuring picture freeze and picture loss have also been provided. The experimental results show that the proposed video quality monitoring system gives good accuracy for artefacts detections.
