Paper Abstract

We present a new method for converting monoscopic video to stereoscopic video. The key characteristic of our proposed method is that it can process non-horizontal camera/object motion existing in most of image scenes. It is well known that the non-horizontal motion causes the vertical parallax to human eyes and accordingly visual discomfort. The proposed methodology is composed of four major steps. First, given a current video frame, we estimate a motion vector for each block by a conventional block matching motion estimation algorithm. The motion vector is composed of horizontal and vertical disparities. Second, the norm of the motion vector is computed for each block. Here, the vertical disparity is eliminated due to the usage of the norm of the motion vector. Due to the unreliability of estimated motion vectors, a low-pass filter is performed on the norm of the motion vector in order to enhance the reliability. Third, each block is shifted to the horizontal direction by the norm of the motion vector, which is transformed to binocular parallax. The shift of blocks in the horizontal direction eliminates the effects of the vertical disparity. Finally, all the shifted blocks are synthesized and a synthesized image is then generated. A stereoscopic image pair being composed of the original image and its associated synthesized image is produced. With proper 3D viewing devices, users can feel 3D depth from seeing the stereoscopic image. Preliminary experiments have demonstrated that stable stereoscopic image pairs can be produced by applying our proposed method to a variety of monoscopic video with non-horizontal camera panning and/or object motion.
