This paper presents a trinocular stereo sequence-coding algorithm based on moving picture experts group (MPEG)-2. Trinocular stereo images are a set of three images; center, left, and right view images are taken at the same time. To reduce the redundancy of a trinocular stereo sequence, we use disparity information, as well as motion information. Three reference images are employed: two reference (previous and future) images for the forward and backward motion vectors and the center view image for the disparity vector (DV). We investigate three temporal prediction structures used for trinocular stereo sequence coding. New macroblock types and variable length code tables that include DV are designed. Experimental results with real test sequences show that the proposed algorithm gives a higher peak signal-to-noise ratio (PSNR) than MPEG-2 and MPEG-2 multiview profile.
