在本文中，我们提出了一种识别包含重复符号和面积符号的矩阵的新方法。该方法由矩阵检测、元素分割、网络构造和矩阵结构分析4部分组成。在网络的构造中，我们将矩阵视为元素通过表示其相对关系的链环连接而成的网络，并考虑其水平投影网络和垂直投影网络。在分析中，我们通过求解由两个投影网络给出的联立方程组来获得产生矩阵的最小矩形面积的可变块模式元素的面积。我们还提出了一种表示矩阵结构的格式来输出矩阵识别的结果。
In this paper, we propose our new method to recognize matrices including repeat symbols and area symbols. The method consists of 4 parts; detection of matrices, segmentation of elements, construction of networks and analysis of the matrix structure. In the construction of networks, we regard a matrix as a network of elements connected each other by links representing their relative relations, and consider its horizontally projected network and vertically projected one. In the analysis, we obtain the areas of variable block pattern elements generating the minimum rectangular area of the matrix by solving the simultaneous system of equations given by the two projected networks. We also propose a format to represent the structure of matrices to output the result of the matrix recognition.
