A historical look at research into the human visual system and its current application toward 3D video distribution
Keith Elliott · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2010
The Human Visual System is extremely powerful, but has characteristics that we can exploit to efficiently store and distribute 3D information. Similar to the basis for chroma subsampling, we can reduce the amount of video data needed for storage and distribution by taking advantage of our body's own limitations. In the late 1980's, researchers at the New York Institute of Technology analyzed how humans perceive video detail and determined that the human visual system does not detect fine detail equally in all directions. This paper will discuss this early research and outline how similar techniques can be used for the storage and distribution of 3D Stereoscopic video. Advantages and disadvantages compared to the other 3D formats are presented and tools that enable individual testing of this technique will be identified and discussed.
