Synthesis of multi viewpoint images at non-intermediate positions

We present an algorithm for the synthesis of multi viewpoint images at non-intermediate positions, based on stereoscopic images. We consider the synthesis of images from virtual camera positions and the synthesis of images for scene reconstruction using stereo displays. The algorithm provides scene reconstruction without geometric distortion and without any restriction to the position of the viewer. All synthesized images are based on extrapolation of a single source image and a single disparity field. This provides low use of bandwidth and compatibility with mono video systems. With teleconferencing images, the generated views were subjectively evaluated as good for viewing positions not more than one half camera baseline from the centre position. Objectively, reconstructed left and right images have PSNR values of 41 dB
