Abstract :
This paper introduces a compression system for automotive stereo algorithms. We propose a method to compress video, disparity and occlusion information based on a 12 bit per pixel H.264/AVC encoder. A rate allocation parameter controls the available bit rate between video and disparity. In addition, the occlusion information is lossless encoded into the bit stream. For driver assistance systems that rely on the disparity information, a higher bit rate can be allocated for the disparity to obtain a better accuracy.
