Computation and Display of 3D Movie From a Single Integral Photography

Integral photography is an auto-stereoscopic technique that allows, among other interesting applications, the display of 3D images with full parallax and avoids the painful effects of the accommodation-convergence conflict. Currently, one of the main drawbacks of this technology is the need of a huge amount of data, which have to be stored and transmitted. This is due to the fact that behind every visual resolution unit, i.e. behind any microlens of an integral-photography monitor, between 100 and 300 pixels should appear. In this paper, we make use of an updated version of our algorithm, SPOC 2.0, to alleviate this situation. We propose the application of SPOC 2.0 for the calculation of complete 3D traveling sequences from a single integral photograph. Specifically, our method permits to generate a sequence of 3D images that simulate the travelling 3D frames captured by a non-static cameraman. In the traveling sequence, we can fix at will, for every frame, the size and position of the field of view, and the parts of the scene that are displayed in front or behind the monitor. Our research is illustrated with experiments in which we generate and display a full traveling sequence.
