Paper Abstract

In this paper we address the real time synthesis of virtual vies for multi viewpoint stereoscopic systems. For the viewpoint dependent generation of virtual vies two approaches can be adopted; a dynamic 3D-model reconstruction of the recorded scene from which the desired virtual views are derived or a disparity compensated interpolation strategy. The latter approach is most feasible for real time system. After a brief review of possible hardware choices we describe, as an example of the disparity compensated strategy, a dynamic programming based disparity estimation algorithm and a disparity compensated interpolation algorithm. For efficient implementation an alternative disparity representation format is presented. Both algorithms are specifically designed for hardware implementation to meet real time constraints. Hardware architectures and implementation considerations are given. Simulations show high quality results for typical teleconferencing scenes. A similar version of the interpolation algorithm is realized and successfully demonstrated in the PANORAMA project.
