Paper Abstract

In stereoscopic television, there is a trade-off between visual comfort and 3D impact with respect to the baseline-stretch of 3D camera. It has been reported that an optimal condition can be reached when we set the baseline-stretch at about the distance of human pupils1. However, we cannot get such distance in case that the sizes of the lens and CCD module are big. In order to overcome this limitation, we attempt to control the baseline-stretch of stereoscopic camera by synthesizing virtual views at the desired location of interval between two cameras. Proposed technique is based on the stereo matching and view synthesis techniques. We first obtain a dense disparity map using a hierarchical stereo matching with the edge-adaptive shifted window. And then we synthesize virtual views using the disparity map. Simulation results with various stereoscopic images demonstrate the effectiveness of the proposed technique.
