Row-Interleaved Sampling for Depth-Enhanced 3D Video Coding for Polarized Displays

Passive stereoscopic displays create the illusion of three dimensions by employing orthogonal polarizing filters and projecting two images onto the same screen. In this article, a coding scheme targeting depth-enhanced stereoscopic video coding for polarized displays is introduced. We propose to use asymmetric row-interleaved sampling for texture and depth views prior to encoding. The performance of the proposed scheme is compared with several other schemes, and the objective results confirm the superior performance of the proposed method. Furthermore, subjective evaluation proves that no quality degradation is introduced by the proposed coding scheme compared to the reference method.
