Disparity remapping for handheld 3D video communications

With the advent of glasses-free autostereoscopic handheld displays, a number of applications may be enhanced by 3D perception, particularly mobile video communications. On handheld devices, front-facing stereo cameras can capture the two views necessary for 3D display. However, the short distance between the user and cameras introduces large disparities and other stereoscopic challenges that have traditionally plagued close-up stereo photography. Maintaining both viewer comfort and 3D fusion under varying conditions is therefore a technological priority. In this paper, we discuss the main stereoscopic concerns of handheld 3D video communications and outline a new post-processing technique to remap on-screen disparities for viewer comfort.
