A plurality of discrete images, typically video images, taken at different viewpoints, as, for example, by a plurality of cameras pointing outwardly on a curving locus are converted to an offset epipolar image. The offset epipolar image includes a plurality of linesets, each such lineset incorporating one scanning line from each of the discrete video images. Each line in the virtual image is reconstructed from a lineset of the epipolar image. The reconstruction may include interpolation between pixel data representing lines from adjacent discrete images and mapping of pixels from one or more lines representing one or more adjacent discrete images onto the pixel line of the virtual image. The nature of the mapping depends upon the viewpoint selected for the virtual image. The system can provide real time stereoscopic telepresence, i.e., a virtual viewpoint images for each eye as the observer moves his or her head.Other References
