Improvement of stereoscopic video by reducing the visual discomfort

Commercially, there are many 3D displays with different resolutions. For this, stereoscopic contents are needed to propagate the displays to commercial markets. For the reduction of production costs, fixed contents are made and used to such displays without any post-production. For instance, it is true that same contents for large-screen are used to small-size screen such as mobile devices. In this case, it is well known that 3D effect is reduced due to the different display resolutions, causing visual discomfort. For this, this paper presents a method of improving the stereoscopic perception according to display resolutions. For the test, 2D+Depth approach is adopted. For this, depth planes are derived based on a depth histogram based on manual operations. By adjusting depth planes, a new depth map is made. Then 2D+Depth produces a stereoscopic image. Experiments performed on various 2D+Depth images validate that the proposed methods deliver more enhanced 3D depth based on subjective evaluation experiments.
