Description
Summary:We propose a new architecture for stereo matching using belief propagation. The architecture combines our fast, fully-parallel processing element (PE) and memory-efficient tile-based BP (TBP) algorithm. On the architectural level, we develop several novel techniques, including a three stage pipeline, a message forwarding scheme, and a boundary message reuse scheme, which greatly reduce the required bandwidth and power consumption without sacrificing performance. The simulation shows that the architecture can generate HDTV720p results at 30 fps when operating at 227MHz. The high-quality depth maps enable real-time depth image based rendering and many other important applications in the 3D TV industry.
