摘要：
Toward estimating global camera motion from encoded video, we propose a robust estimation based on an outlier rejection scheme. The extended Kalman filter and the Levenberg-Marquardt method are implemented for the estimation. Both implementations show promising results, but from computational aspect, the LM method is more efficient than the extended Kalman Alter in our implementation.
