Practical Stereo Matching Approach for Stereoscopic Video and Its Application

Abstract

Stereoscopic contents, such as 3D movies, Digital Signage and a glasses-free 3D etc. have recently become more available to the general public. Meanwhile, in terms of labor cost, creating stereoscopic contents still costs more money because it requires several manual labor processes such as drawing a depth map. In the creation of stereoscopic contents, depth information plays an important role for achieving a comfortable product by controlling stereoscopic effect and the depth information can be obtained by stereo matching methods with a set of input images. In this paper, we introduce an innovative approach suitable for the creation of stereoscopic contents, which is combining a fast method and a high-accuracy method. Our approach is constructed from the feature of depth perception and results of our questionnaire survey for verifying cognition of binocular disparity on background domain in stereoscopic contents. We also introduce our application for obtaining depth information by using our approach. Our application is interactive and intuitive, thus users can easily adjust parameters and obtain the results visually. Finally, the processing speed is evaluated by speed measurement and comparison with existing stereo matching methods.
