Disparity-based view morphing—a new technique for image-based rendering
Ho-Chao Huang, Shung-Hua Nain, Yi‐Ping Hung, Tsê Chêng · 1998
This paper proposes a new powerful technique for image-based rendering, i.e., the disparity morphing technique. The disparity morphing depends on the estimated disparity map for each image pair based on the epipolar geometry. The epipolar constraints can not only speed up the searching of correspondences for disparity estimation, but also improve the accuracy of the estimated disparity maps. Then the forward and backward morphing functions are defined based on the estimated disparity maps. Notice that the forward and backward morphing functions are usually not linear and not similar to the traditional image morphing functions. Finally, the interpolation function is defined to deal with the object occlusion problems correctly. The resulted transition views are almost the same as what viewers can see in the real world. For object movie systems, the disparity morphing can generate interpolated views between two or more viewing directions. For panoramic imaging systems, the disparity morph...
