窗口信函邮政编码分割与识别系统的研究和实现

文中介绍了窗口信函邮政编码分割与识别系统的研制。根据投影原理首先分割出信封图像上的文字行，然后再在行内分割邮政编码数字的图像。数字的识别采用两种方法分别进行，对两个识别结果经适当的组合形成最后的识别结果。采用了一种基于统计规则的多分类器组合方法，使得组合的结果不仅识别高而且错识率低。

RESEARCH AND IMPLEMENTATION OF A POSTAL NUMERALS SEGMENTATION AND RECOGNITION SYSTEM FOR WINDOW LETTERS

The research and implementation of postal numerals segmentation and recognition system for window letters are discussed in the paper here. Row information of characters is gained from envelope's image according to projection, then the sub image of postal numerals is segmented. The numerals are recognized by two independent classifiers, and their results are combined to form final results. A new combination mode of multiple classifiers based on statistical rules is utilized in order to achieve good performance for high recognition rate and low substitution rate. It is proved that the performance of the system is good, which suffices to the requirement of the practical use.
