摘要: 介绍了应用于工程图形和符号识别的三种时间序列建模方法,分别为:复数域自回归横型、复数域非线性指数自回归模型和复数域阈值非线性自回归模型。分析了每种模型的性质和适用范围,设计了针对不同模型的模式分类器。理论和试验都证明了时序建模方法在工程图形和符号识别领域具有良好的应用效果。

Abstract: Three time series modeling approaches applicable for engineering shape and symbol recognition are presented, i. e. Complex Autoregressive Model, Complex Nonlinear Exponential Autoregressive Model and Complex Threshold Nonlinear Exponential Autoregressive Model. The property and applicable range of each model is analyzed, and the pattern classifier is also designed with respect to each model. Both theory and experiment result prove that the time series modeling technique can show good effect for the application of recognition of engineering shape and symbol.
