DVQ (which stands for "digital video quality") is a metric for evaluating the visual quality of digitized video images. Other video-quality metrics have been proposed, but it appears that each of them (1) may be based on mathematical models that are not related closely enough to the characteristics of human perception, in which case it may not measure visual quality accurately; or (2) may entail such large amounts of memory or computation that the contexts in which it can be applied are restricted. In contrast, DVQ was developed in an effort to incorporate mathematical models of human visual processing while maintaining computational efficiency so that accurate metrics can be computed in real time by use of modest computational resources.
