Overview of full-reference video quality metrics and their performance evaluations for videoconferencing application

摘要

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: Ecole polytechnique federale de Lausanne database, live mobile database, and two Orange Lab databases, with a large sample of distortion types (transmission errors, encoding bit rates, etc.).
