    4. 4. Observations Stereoscopic 3DTV is quite an old concept  Almost as old as its 2D counterpart 2D has flourished  3D “failed” to be popular Stereoscopic 3D is simpler  Based on human visual system and perception  Usually creates “mismatches” of various 3D cues  Current research on stereoscopic 3DTV is mostly targeted to overcome such problems
    5. 5. An Overview of Candidate 3DTVTechniques Stereoscopic 3DTV  Simplest, based on “perception”  Viewer discomfort  Autostereoscopic  Head-tracking stereoscopic Holographic 3DTV  Basic principle -1948, first holograms – 1960  Based on physics : duplication of light field  Digital holographic techniques  Holographic cameras  Experimental holographic motion pictures – 1989  Still at basic reseach phase
    6. 6. Integral Imaging Based 3DTV A principle known since 1908 Based on “capturing a scene from different angles” And then reverse projection from corresponding angles Lenslet arrays Variants can be classified under “holographic techniques”
