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.   Studies on thermodynamics and kinetics about pyrolysis mechanism of carbon matrix precursor CH3ArCH2NH2 期刊论文  OAI收割 CHEMICAL JOURNAL OF CHINESE UNIVERSITIES-CHINESE, 2001, 卷号: 22, 页码: 800-804 作者:  Wang, H;  Zhai, GH;  Yang, HF;  Wen, ZY;  Shi, QZ   |  收藏  |  浏览/下载：19/0  |  提交时间：2018/05/31 carbon matrix precursor  pyrolysis mechanism  AMI and DFT method  thermodynamics kinetics   Theoretical study on intramolecular hydrogen transfer involving amino-substituted perylenequinone 期刊论文  OAI收割 DYES AND PIGMENTS, 2000, 卷号: 47, 期号: 3, 页码: 277-284 作者:  Liu, W;  Zhang, HY;  Chen, DZ;  Zhang, ZY;  Zhang, MH   |  收藏  |  浏览/下载：21/0  |  提交时间：2019/04/09 Ami Method  Amino-substituted Perylenequinonoid Photosensitizer  Intramolecular Hydrogen Transfer  Amino-substituted Perylenequinone  Perylenequinonoid Photosensitizer   Theoretical study on electron transfer in biological systems (III) - Intramolecular electron transfer in metal-containing spiro pi-electron system 期刊论文  OAI收割 SCIENCE IN CHINA SERIES B-CHEMISTRY, 1999, 卷号: 42, 期号: 1, 页码: 77-82 作者:  Zhai, YF;  Jiang, HL;  Zhu, WL;  Gu, JD;  Chen, JZ   |  收藏  |  浏览/下载：24/0  |  提交时间：2019/01/08 electron transfer  electric field  AMI method  electron transfer matrix elements
