	Approach for detecting crowd panic behavior based on fluid kinematic features and entropy (EI CONFERENCE) 会议论文 OAI收割 International Workshop on Advanced Computational Intelligence and Intelligent Informatics, IWACIII 2011, November 19, 2011 - November 23, 2011, Suzhou, China 作者: Li Y.; Li Y.; Li Y.; Zhang X.; Zhang X. 收藏 \| 浏览/下载：35/0 \| 提交时间：2013/03/25 Crowd panic behavior detection is an important task in video analysis and event recognition whose purpose is to detect when the panic behavior happened and alarming the abnormal event timely. In this paper the crowd is regard as a fluid and the crowd motion is described by four fluid kinematic features (divergence vorticity gradient tensor invariant and rotation tensor invariant). To discriminate the panic event from normal crowd behavior an information entropy is calculated as a high level feature based on the fluid kinematic features. Experimental results show that the entropy raised dramatically once a panic event happened.
	Qualitative determination of the components of textile products using near infrared spectroscopy (EI CONFERENCE) 会议论文 OAI收割 International Symposium on Photonics and Optoelectronics, SOPO 2010, June 19, 2010 - June 21, 2010, Chengdu, China 作者: Chen X.; Chen X.; Chen X.; Wang D. 收藏 \| 浏览/下载：37/0 \| 提交时间：2013/03/25 In the paper A total of 40 pure or two-mixed textile weaves were prepared and classification of these samples was introduced using near infrared spectroscopy (NIRS) all textile samples are selected among four classes which are Cotton-Terylene Cotton-Polyurethane Cotton and Terylene according to theirs components. Near infrared diffuse reflectance spectra of the samples were collected Mahalanobis distance was used to discriminate the samples coupled with principle components analysis (PCA) the results showed that near infrared spectroscopy could determine which class one textile weave belongs to easily comparing with traditional methods. In addition the expectation of the further research on qualitative determination of textile products by NIR technology was discussed in the end of this paper. 2010 IEEE.
