	Optimization on motion estimation algorithm based on H. 264 (EI CONFERENCE) 会议论文 OAI收割 2010 3rd International Conference on Advanced Computer Theory and Engineering, ICACTE 2010, August 20, 2010 - August 22, 2010, Chengdu, China Wen X.; Li G. 收藏 \| 浏览/下载：55/0 \| 提交时间：2013/03/25 Motion estimation is a very important part of video compression. As a result of using precision of motion vector in H.264 encoder the computational cost increases rapidly and motion estimation is the most time-consuming stage. In this paper based on the UMHexagonS algorithm an optimized algorithm is proposed based on the dynamic search window selection big hexagon and small hexagon search mode respectively which saves motion estimation time effectively with a little quality loss. Experiments with some typical video sequences show that compared to the original UMHexagonS algorithm this new algorithm can save about 17.851 % motion estimation time and reduce the complexity of original scheme as well as enhance the real time performance of encoder and almost has no changes in the reconstructed picture quality and bitrates. 2010 IEEE.
	Adaptive backstepping control of a dual-manipulator cooperative system handling a flexible payload (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China 作者: Li Y.; Li Y.; Li Y.; Li Y. 收藏 \| 浏览/下载：18/0 \| 提交时间：2013/03/25 Two manipulators handling a flexible payload are studied based on adaptive backstepping control theory. Considering the complexity of the dynamic model the obtained model is divided into a slow subsystem describing the large rigid motion and a fast subsystem expressing the elastic vibration by singular perturbation theory. A cooperative controller is designed based on adaptive backstepping control. The slow subsystem can complete system trajectory tracking performance. The fast subsystem can suppress the elastic vibration of the system. Stability of the system is proved by using Lyapunov stability theory. The validity of the proposed scheme is demonstrated by simulations. 2010 IEEE.
