Performance Analysis of a No-Reference Temporal Quality Assessment Metric for Videos Impaired by Frame Freezing Artefacts

Abstract

40 Abstract-In This paper, a temporal video quality assessment metric has been studied and evaluated on the basis of its ability to detect frozen video frames in a digitally transmitted video sequence and assess the quality accordingly. The metric is a temporal quality method that is centered around measuring the annoyance of frame freeze duration. This metric uses mean square difference (MSD) value between video frames to mark freeze events and builds a mapping function based on such durations of freeze to estimate the objectivemean opinion score (MOS). Two test scenarios have been designed for the analysis, Single freeze and multiple freeze experiment, keeping in view the recommendations of international telecommunication union (ITU). The analysis has been done with the help of MATLAB simulations and finally some limitations of the temporal quality metric are shown at the end of the paper.
