This paper describes a scheme for recognizing human actions from a video sequences. The proposed method is an extension of the Motion History Image(MHI) method based on the ordinal measure of accumulated motion  which is robust to variations of appearances. We define the accumulated motion image(AMI) using image differences firstly. Then the AMI of the video sequencesis resized to a MN regulation following the standard of training phases. Finally  we employ Support Vector Machine(SVM) as a classifier to distinguish the current activity in target video sequences. In a word  our proposed algorithm not only outperforms the state of art on public available KTH data set and Weizmann data set  but also proves practical to some real world applications  in addition  this method is computationally simple and able to achieve a satisfactory accuracy.   Discuss on the researching and using geo-spatial technology in the history changing of the Silk Road 会议论文  OAI收割 2008 Proceedings of Information Technology and Environmental System Sciences: Itess 2008, Vol 2, Beijing Bi, Hantao; Wang, Xingxing Y. 收藏  |  浏览/下载：148/0  |  提交时间：2014/12/07 the Silk Road  geo-spatial information technology  history research  ARCTIC ATMOSPHERE  GAS-EXCHANGE   Historical Review of Antitumor Drug Research in China 期刊论文  OAI收割 World Sci-Tech R and D, 2002, 卷号: 24, 期号: 3, 页码: 19-23 作者:  Xu Bin   |  收藏  |  浏览/下载：12/0  |  提交时间：2019/01/08 antitumor drugs  research history  review   Long-term change in village-scale ecosystems in China using landscape and statistical methods 期刊论文  iSwitch采集 ECOLOGICAL APPLICATIONS, 2000, 卷号: 10, 期号: 4, 页码: 1057-1073 作者:  Ellis, EC;  Li, RG;  Yang, LZ;  Cheng, X 收藏  |  浏览/下载：45/0  |  提交时间：2019/10/10 agroecology  anthropogenic ecosystems  China  data quality  ecological history  ecotope  Geographic Information Systems  land use  landscape classification  Monte Carlo uncertainty analysis  research synthesis  traditional agriculture
