In this paper we present a no-reference video quality metric based on individual measurements of three artifacts: blockiness, blurriness, and noisiness. The set of artifact metrics (physical strength measurements) was designed to be simple enough to be used in real-time applications. The metrics are tested using a proposed procedure that uses synthetic artifacts and subjective data obtained from previous experiments. The technique has the advantage of allowing us to test each metric on videos which contain only the desired artifact signal or a combination of artifact signals. Models for the overall annoyance based on a combination of the artifact metrics using both a Minkowski metric and a linear model are developed. Both models present a very good correlation with the data and show no statistical difference in their performances.
