Coding of Depth Images for 3DTV

In this short paper a brief overview of the topic of coding and compression of depth images for multi-view image and video coding is provid ed. Depth images represent a convenient way to describe distances in the 3D scene, useful for 3D video processing purposes. Standard approaches for the compression of depth images are described and compared against some recent specialized algorithms able to achieve higher c ompression performances. Future research directions close the paper.
