With the development of video services available on various devices (mobile, PC, tablet, television, etc.), the end user experiences and requirements have changed. Objective video quality assessment tools and metrics are increasingly complex and adapted to different types of service context. Compared with other reviews of quality metrics, the full-reference (FR) video quality metrics reviewed (particularly, ViS3, SSIMplus, video multimethod assessment fusion, and open perceptual video quality metric) are more recent and have not been compared with each other yet. We compare and evaluate the performance of 10 FR metrics with respect to their accuracy in predicting the subjective perceived quality for the videoconferencing application. Emphasis is given to the metrics evaluating the visual quality (from human perception). A detailed statistical study is carried out on four subjective databases: École polytechnique fédérale de Lausanne database, live mobile database, and two Orange Lab databases, with a large sample of distortion types (transmission errors, encoding bit rates, etc.).
Offering the best Quality of Experience (QoE) is the challenge of all the video conference service providers. In this context it is essential to identify the representative metrics to monitor the video quality. In this paper, we present Machine Learning techniques for modeling the dependencies of different video impairments to the global video quality perception using subjective quality feedback. We investigate the possibility of combining no-reference single artifact metrics in a global video quality assessment model. The obtained model has an accuracy of 63% of correct prediction
