摘要: 提出了一种新的关联矩阵——角度矩阵来表达关联图,分别采用邻接矩阵、拉普拉斯矩阵、距离矩阵和角度矩阵来数字化表达关联图。初步实验结果表明,图的谱方法是一种有效表达空间目标形状信息的方法,其中选择角度矩阵作为关联矩阵的效果最好。Abstract: We put forward a new relational matrix,angular matrix.Preliminary research shows that the spectral method of graph is effective for representation and measurement of 2D spatial object's shape and the angular matrix can represent geometric shape of spatial object more accurately and precisely than other relational matrix,such as adjacent matrix,Laplacian matrix,and distance matrix.
