光盘中存放的是书中涉及的源代码，为了便于读者学习，已将完整的程序分割开，读者在使用的时候，最好按照书中介绍的内容一步一步的实现。其中第1章提供的是相关算法的核心程序，第5章由于是一个综合的商业程序，涉及到各种技术，如果读者需要图像识别部分的程序，可以发邮件至2wintech@126.net与我们联系。另外，书中涉及到的图片等资源，保存在光盘的对应目录下。-stored in the CD book is the source code, in order to help readers learn, has a complete separate procedures, the use of the readers, the best in accordance with the contents of the book introduced step by step to achieve. The first chapter provides a correlation algorithm is the core program, Chapter 5 is due to an integrated business processes, involving a variety of technologies, if the reader needs Image Recognition part of the program, you may e-mail 2wintech@126.net contact us. In addition, the book relates to the pictures and other resources stored in the corresponding CD-ROM directory.
