Bandwidth-constrained motion estimation for real-time mobile video application
This paper addresses the memory bandwidth problem of motion estimation in resource limited mobile video applications by an integrated bandwidth rate distortion optimization framework. The simulation result shows up to 86% bandwidth saving while keeps equivalent rate-distortion (R-D) performance and meets real time target compared with H.264 reference software for low motion CIF size video. For high motion sequence, the result shows our algorithm could better allocate the available bandwidth for high motion macroblock without violating the real time constraint when search range is set to ±16.
