Objective video quality assessment method for evaluating effects of freeze distortion in arbitrary video scenes
2007
With the development of the broadband IP networks, video distribution, streaming, and communication services
over networks are rapidly becoming common. To provide these services appropriately, we must design, monitor,
and manage their quality based on subjective video quality. Therefore, we need an objective quality assessment
method that enables video quality to be evaluated from video characteristics easily and quickly. We have
already proposed an objective video quality assessment method for freeze distortion in network video services
by considering the perceptual characteristics of short freeze distortion. In this previous method, we derived the
objective video quality under the assumption that all freeze lengths in the video are constant. However, it was
impossible to derive objective video quality when arbitrary freeze lengths occur because of network degradation in
real services. We propose an objective video quality assessment method for arbitrary freeze lengths by extending
the previous method and confirm that it can estimate subjective video quality with good accuracy for real
applications. The correlation coefficient between subjective and objective quality is 0.94.
