Several objective quality metrics have been proposed for images, but video quality assessment has received relatively little attention and most video quality metrics have been simple extension of metrics  ...  Quality assessment plays a very important role in almost all aspects of multimedia signal processing such as acquisition, coding, display, processing etc.  ...  Full reference quality metrics assume the availability of a "perfect" reference video and attempt to assess the fidelity of the test video with respect to this pristine original.  ...

We survey recent developments in multimedia signal quality assessment, including image, audio, video, and combined signals.  ...  Owing to the sensory nature of these signals, perceptual models lie at the heart of multimedia signal quality assessment algorithms.  ...  Temporal quality is measured using optical flow fields computed from the reference video using our own multi-scale extension of the Fleet and Jepson phase-based optical flow estimation technique [21,  ...
