This paper proposes a new technique for generating multiviewpoint video from a two-view stereo video sequence. The two-view stereo video can be easily obtained by using inexpensive two-view stereo video capture devices. For each image pair in the two-view stereoscopic video signals, our system first estimates the corresponding points of each pixel based on an epipolar constraint. A smoothing algorithm is used to smooth the estimation result, and then generate the disparity maps for each image pair. Then the proposed system can generate multiple perspective stereo video by interpolating or extrapolating the original views based on the generated disparity maps. Compared to the traditional method of capturing the multiple perspective video directly, our method can significantly reduce both the difficulties of video capturing and processing as well as the amount of video data
