5. 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

6. An Overview of Candidate 3DTV
Techniques
 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

7. 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”
