I. Introduction
With the development of three-dimensional 3D display and network technologies, three-dimensional television (3DTV) technology has a widespread prospect of applications [1]. However, 3DTV system is limited in bandwidth, memory, and other system resources, various coding algorithms [2] have been developed to compress video data, resulting in the occurrence of blurring, blocking, ringing, and other distortions. Therefore, how to quantify the distortions of 3D content is an issue in 3DTV system.
