    "abstract": "With the emergence and proliferation of digital video compression in television systems, there is an increasing requirement for effective methods to evaluate picture quality. In this paper, we describe traditional and novel objective and subjective test methods. We review standard methods to subjectively evaluate picture quality, outline their limitations and suggest ways to change these subjective methods. In addition, we also discuss research into objective methods that employs perception-based models with easily measurable parameters that could give a high degree of correlation with subjective evaluation methods. Finally, we draw some conclusions about the types of research needed to further the development of methods for picture quality evaluation.",
