On quality assessment in the delivery of mobile video

Along with a rapid growing volume of video on communication systems, we see the emergence of many new video applications and services. As video plays a larger role in our communications, the need for accurate, real-time video quality measurement becomes more important for these applications and services. In this paper, we present an emerging application for quality measurement of transmitted videos, especially delivered for mobile devices, and, in that context, provide a brief survey of the state-of-the-art in no-reference quality models for various kinds of video distortion. We then discuss some challenges that arise when incorporating quality measurement into practical systems.
