3D activity measurement for stereoscopic video

One of the most challenging issues in the 3D visual research field is how to quantify the visualization displayed over the virtual 3D space. To seek an effective method of quantification, it is necessary to measure various important elements related to different depths of 3D objects. In this paper, we propose a new framework to quantify the 3D visual information, termed 3D activity by measuring natural scene statistics (NSS). In the simulation, we verify the effectiveness of 3D activity to quantify the degree of freedom of 3D space in various aspects: disparity and motion.
