Stereoscopic depth perception measurement for 2D/3D converted contents

Owing to the development of 3D industry, the number of 3D contents is growing. However, there does not exist yet a clear, precise criterion to objectively evaluate the quality of these contents. In this paper, we propose a method to measure, among 2D-plus-Depth image quality measure factors, the stereoscopic depth perception. To measure the variety of depth values and the amount of depth-perceived objects, which are assumed to be depth perception-related, we propose two methods, which are based on the histogram and gradient of depth image, respectively. Experimental results show that the proposed methods can accurately estimate depth perception quality.
