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.   Image quality assessment based on gradient complex matrix (EI CONFERENCE) 会议论文  OAI收割 2012 International Conference on Systems and Informatics, ICSAI 2012, May 19, 2012 - May 20, 2012, Yantai, China 作者:  Wang Y.;  Wang Y. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 An image quality assessment model based on gradient complex matrix is proposed. The vertical and horizontal gradient information of grayscale image is calculated. Complex number is used to construct the measuring matrix. Singular value decomposition is performed in order to obtain the main structure information of the image. The singular value feature vectors of the image gradient complex matrices corresponding to the reference image and the distorted image are used to measure the structural similarity of the two images. PSNR is taken as a tool to evaluate the gradient distribution similarity. Their properties are analyzed by using LIVE database and nonlinearity regression function. 2012 IEEE.   Exact analytical solutions for the generalized non-integrable nonlinear Schrodinger equation with varying coefficients 期刊论文  OAI收割 PHYSICS LETTERS A, 2010, 卷号: 374, 期号: 48, 页码: 4838-4843 作者:  Yan, Zhenya   |  收藏  |  浏览/下载：12/0  |  提交时间：2018/07/30 Generalized non integrable nonlinear  Schrodinger equation with varying  coefficients  Similarity transformation  The tri function method  Analytical solutions   Turbulent intensity and its similarity function over an Inner Mongolian grassland during spring 期刊论文  iSwitch采集 SCIENCE CHINA-EARTH SCIENCES, 2010, 卷号: 53, 期号: 5, 页码: 773-780 作者:  Yue Ping;  Niu ShengJie;  Hu YinQiao;  Zhang Qiang 收藏  |  浏览/下载：32/0  |  提交时间：2019/10/08 turbulent intensity  variance of velocity  similarity function  grassland
