在过去二十来年,模式识別有了很大的发展,其应用范围遍及遥感、文字识别、生物医学图象和信号的分析、产品自动检测、语言理解、机器视觉等方面.为了能用计算机对模式进行有效的描述、分析和识别,提出了许多数学方法.概括起来,主要有统计法和语言结构法两大类.两类方法都要考虑模式表示、分类或结构分析等基本问题.
In the past two decades, pattern recognition has been greatly developed, and its applications include remote sensing, character recognition, biomedical image and signal analysis, product automatic detection, language understanding, machine vision, etc. In order to be able to use computers To describe, analyze and identify the model effectively, a lot of mathematical methods are put forward.Cumulatively, there are two main categories: statistical method and linguistic structure method.These two kinds of methods must consider the basic problems of pattern representation, classification or structure analysis.
