DM码是一种常见的二维条形码，提供一个编码器，供学习参考。-DM code is a common two-dimensional bar code, providing an encoder, for the study reference.

OCR算法代码。 这不是一个完整的系统，没法生成可执行程序。 代码基于Linux/KDE开发，用到了C++标准模板库。 代码的目的是向读者展示一个OCR系统包括哪些部分，如何工作， 读者可以借鉴这些代码，改动后用到自己的系统中。 由于这是从一个完整的OCR系统中抽取的部分代码， 所以这些代码无法单独编译。 两个*.dat文件如下： char_data.dat：字符特征数据 words_de.dat：词库（后处理用） 如果需要完整实用的中文OCR代码，可以和PRTsinghua@hotmail.com联系。-OCR algorithm code. This is not a complete system, we can not generate executable. Based on the Linux code/KDE development, use the C standard template library. The code is intended to show readers an OCR system, including which parts work, readers can learn from these code changes after their use in the system. As this is from a complete OCR system taking part code, so code can not be compiled separately. 2*. dat following documents : char_data.dat : Character Feature Data words_de.dat : Thesaurus (after treatment) for a complete practical needs if the Chinese OCR code, and PRTsinghua@hotmail.com links.
