为有效识别出新维文中大小写同形字母，分析新维文的特点，提出一种基于模板匹配的大小写同形字母识别算法。根据同形字母中大写字母外轮廓大而小写字母外轮廓小的特点，统计字母外轮廓大小与全文字母外轮廓平均大小的比例值，进行字母的大小写判断。分析结果表明，该方法有效克服了传统模板匹配方法容易混淆同形字母的大小写的缺点，提高了系统的识别率。

To efficiently identify the case-same shape letters in the Uighur new writing ,after analyzing the characteristics of the Uighur new writing ,a method based on the template matching was proposed for distinguishing case-same shape letters .The ratio of the current letter’s outer-contour-size and the average values of all letters’s outer-contour-sizes were calculated ,then upper-case and lowercase letters were identified according to the characteristics that the outer contour of uppercase letters was larger than that of lowercase letters in the case-same shape letters .The results show that the method is effective to overcome the short-comings of the traditional template matching method that the uppercase and lowercase of the case-same shape letters are easy to be confused ,and it significantly improves the recognition rate of the system .
