To address the problem, we define a novel similarity function including two parts in this paper. The first part is Hausdorff distance between shapes which is calculated by exploiting shape context that is rotation and scale invariant as the distance metric. The second part is the cost of matching between centroids. Unlike the traditional method, we use the centroid as reference point to obtain its shape context that embodies global information of the shape. Experiment results demonstrate that the function value between shapes is rotation and scale invariant and the matching accuracy of our algorithm is higher than that of previously proposed algorithm on the MEPG-7 database.   The shape edge measure of automobile airbag based on image processing (EI CONFERENCE) 会议论文  OAI收割 2012 IEEE 5th International Conference on Advanced Computational Intelligence, ICACI 2012, October 18, 2012 - October 20, 2012, Nanjing, China 作者:  Li Y.;  Wang Z.;  Wang Z.;  Li Y.;  Li Y. 收藏  |  浏览/下载：33/0  |  提交时间：2013/03/25 At present  micrometer is used for measure the shape edge of automobile airbag. There are some shortcomings in this method. The number of test points is limited. Test data is not comprehensive. Detection speed is slow and a fixture can only test a kind of airbag. The method of airbag shape edge detection based on image processing is researched in this paper. The image of airbag is collected by CCD  and then it is sent to the computer to be processed and segmented. The edge of image is extracted through Canny edge detection algorithm in order to acquire shape edge of airbag in this paper  and the image similarity degree are calculated to provide the information of matching in the template matching process. Finally the comprehensive test shape edge of airbag is realized. The experimental results show that the detection method is effective feasible  intuitive and clear. 2012 IEEE.   Potent and novel 11 beta-HSD1 inhibitors identified from shape and docking based virtual screening 期刊论文  OAI收割 BIOORGANIC & MEDICINAL CHEMISTRY LETTERS, 2011, 卷号: 21, 期号: 19, 页码: 5739-5744 作者:  Xia, Guangxin;  Xue, Mengzhu;  Liu, Lin;  Yu, Jianxin;  Liu, Haiyan   |  收藏  |  浏览/下载：33/0  |  提交时间：2019/01/08 11 beta-HSD1 inhibitor  Virtual screening  Docking  Shape similarity   Computer simulation research on cognitive mechanism of human vision (EI CONFERENCE) 会议论文  OAI收割 International Conference on Measuring Technology and Mechatronics Automation, ICMTMA 2010, March 13, 2010 - March 14, 2010, Changsha, China Ke H.; You W. 收藏  |  浏览/下载：38/0  |  提交时间：2013/03/25 The development of intelligent system which accorded with human cognitive mechanism will exert a profound influence on national defense  economy  education  culture and etc. A computer simulation method according with cognitive mechanism of human vision was proposed on the basis of Structural Decomposition Theory. Many basic shape feature information tables of similar object from different side can determine a kind of object uniquely. System weighted basic shape features in two different information tables by membership degree and then calculated similarity. The identifying object which had the maximum similarity with it in system was what we needed. The system used 83 pictures of 6 kinds of objects with different side for training and testing. The experiment results demonstrated  task of basic shape extraction  object recognition and others can be completed effectively with the method in paper. The method in paper can be a new attempt on computer simulation method according with cognitive mechanism of human vision from cognitive field. 2010 Crown Copyright.
