Accelerometers have appeared on many camcorders, cameras and mobile phones. We present algorithms that estimate camera movement from accelerometer readings and apply the estimation to significantly improve the compute-intense motion estimation in video encoding. We have implemented a working prototype that simultaneously captures video and three-axis(More)
Motion estimation/compensation has been employed in almost all modern video coding standards to effectively reduce temporal redundancy. The encoder complexity is dominated by the motion estimation. In this paper, we present a novel approach to significantly reduce the computation cost of motion estimation in video encoding by employing accelerometers(More)
