Firstly  the application background of 40Gbit/s system  the key using technologies and the shortcomings and advantages of 40Gbit/s system are possessed. Secondly  an application program of 40Gbit/s system based on dispersion compensation is given. At the same time  this program is analyzed. Thirdly  this program is compared with another program which has been widely used in 40Gbit/s system. Finally  the compared results show that this program is able to improve the transmission efficiency apparently. 2012 IEEE.   Parallel estimation of translation for video stabilization (EI CONFERENCE) 会议论文  OAI收割 2010 6th International Conference on Wireless Communications, Networking and Mobile Computing, WiCOM 2010, September 23, 2010 - September 25, 2010, Chengdu, China 作者:  Wang H.;  Liu G.;  Wang H.;  Wang H.;  Wang H. 收藏  |  浏览/下载：99/0  |  提交时间：2013/03/25 Translation motion estimation is the major aspect of video motion compensation  especially in two-dimensional turntable. This paper presents a robust parallel estimation algorithm of translation in video stabilization system. The equivalent model of translation that derived is accorded with small rotation angle comparatively. A parallel algorithm based on grey mapping is used in local motion estimation to shorten the estimation time and improve the computation efficiency. After local motion vectors are calculated  a fast filter can detect the spurious vectors avoiding possible jerks. The suggested translation estimation algorithm has been implemented on NVIDIA GTX 260  the experimental results show that  the average time of the estimation and compensation finished in 16 ms/frame  and stabilize 1k1k pixels sequence gray video up to 60 frames/s. 2010 IEEE.
