摘要
首次提出了矩阵灰色绝对关联度的概念,并对相应性质进行了数学证明,给出了曲面灰色关联分析的实例验证.已有灰色关联理论只能进行序列之间的关联分析,其几何意义是曲线之间的整体相似性比较;给出的矩阵灰色绝对关联度可以进行相同维度矩阵之间的关联分析,其几何意义是曲面之间的整体相似性比较.矩阵灰色关联分析有望为诸如环境监测点位优化、图像处理中的人脸部位提取等二维信号处理提供新的技术手段.
Absolute grey relation degree of matrix is proposed as a new concept in this paper. Moreover mathematical justification and surface verification cases using this theory are given. Available grey relation degree theory is limited in using in sequence relation analysis to reveal and compare comparabilily of whole curves. The theory presented in this discourse can be used in relation analysis of equal dimension matrixes. Its geometric meaning is expanded to comparability comparison of whole surfaces. This theory can be used as a new technical approach for two dimensional signal processing such as en vironmental monitoring site optimization and feature extraction in human face.
