| Abstract(in English) | With the development of the broadband IP network, video communications and distribution services are beginning to become common. In order to provide these services appropriately, we must manage them based on subjective video quality, in addition to designing a network system based on it. Therefore, an objective quality assessment model that enables video quality to be evaluated from video characteristics easily and quickly is needed. Authors have already proposed the objective video quality assessment method for freeze distortion in video distribution services by considering perceptual characteristics of freeze distortion. In this paper, we adopt our proposed method to video communication services and show some problems. Specifically, we improve the performance of our method by refining on parameters of our established model. we also propose the better method by considering the characteristics of user's perception more smartly. We confirmed that our method can achieve target accracy by the result of varidation. |
