vc开发的针对复杂背景下的DM码的识别，实现了自适应阈值分割，快速定位等

C# 生成二维码，利用DataMatrix库生成DM二维码并且进行边缘校准，方便打印张贴，可以批量生成放入A4纸进行打印。

WinCE驱动调试助手是一个用来动态管理WinCE流驱动的小工具，支持WinCE4.2、WinCE5.0和WinCE6.0。在WinCE5.0和6.0中，DM也可动态管理系统启动时加载的驱动。该工具也支持基本的注册表操作，包括导入导出、查找、新建、删除、编辑和重命名等。 在英文版的操作系统中，驱动调试助手不能正常显示。此时可将simsun.ttc与DM.exe放在同一目录下，并点击菜单“Support CHS”以支持显示中文。

用java生出二维码图片保存到本地文件夹，好用，有问题问我(dm格式的)，以前做的qr格式的，qr格式做的图片有点大，发彩信不好发，所以就做了dm格式的，现在大概有1.5k那么大吧，

1.Suppose that a data warehouse consists of four dimensions, date, spectator, location, and game, and two measures, count and charge, where charge is the fare that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. (a)Draw a star schema diagram for the data warehouse.
