  Progress in image sensors and computation power has fueled studies to improve
acquisition, processing, and analysis of 3D streams along with 3D
scenes/objects reconstruction. The role of motion compensation/motion
estimation (MCME) in 3D TV from end-to-end user is investigated in this
chapter. Motion vectors (MVs) are closely related to the concept of
disparities, and they can help improving dynamic scene acquisition, content
creation, 2D to 3D conversion, compression coding, decompression/decoding,
scene rendering, error concealment, virtual/augmented reality handling,
intelligent content retrieval, and displaying. Although there are different 3D
shape extraction methods, this chapter focuses mostly on shape-from-motion
(SfM) techniques due to their relevance to 3D TV. SfM extraction can restore 3D
shape information from a single camera data.
