A Recognition Method of Matrices by Using Variable Block Pattern Elements Generating Rectangular Area
نویسندگان
چکیده
In this paper, we propose our new method to recognize matrices including repeat symbols and area symbols. The method consists of 4parts; detection of matrices, segmentation of elements, construction of networks and analysis of the matrix structure. In the construction of networks, we regard amatrix as anetwork 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 pr0-pose aformat to represent the structure of matrices to output the result of the matrix recognition.

متن کاملApplication of Pattern Recognition Algorithms for Clustering Power System to Voltage Control Areas and Comparison of Their Results
Finding the collapse susceptible portion of a power system is one of the purposes of voltage stability analysis. This part which is a voltage control area is called the voltage weak area. Determining the weak area and adjecent voltage control areas has special importance in the improvement of voltage stability. Designing an on-line corrective control requires the voltage weak area to be determi...
