Description: 列车时刻表查询系统
本系统采用的是PowerBuilder 9.0、ODBC、powerbuilder自带的数据库相结合的方法(之所以使用自带数据库是因为便于发布可执行程序),将所有收集的数据信息存储到数据库中,再通过程序调用这些数据信息实现各种查询及管理。
该系统的理论及技术简单,系统维护工作容易,并可不断更新。所以本系统在技术上是可行的。而且该系统对于操作环境的要求不高,一般的计算机都可以运行。
用户界面实现以下三个模块的设计:
a. 站站查询模块 实现任意两个站点的路线查询
b. 车次查询模块 实现任意车次的信息查询
c. 站点查询模块 实现任意站点的车次信息查询
rar包中包含了源码和发布程序,源码使用PowerBuilder 9.0可直接看,发布程序不需要安装PowerBuilder 9.0就可以执行(执行test.exe之前,请双击reg注册表进行注册即可,卸载请自行删除注册表)-Train schedule inquiry system
The system uses a PowerBuilder 9.0, ODBC, powerbuilder own method of combining the database (the reason is because the ease of use comes with a database distribution of executable program), all collected data stored in the database, and through the program calls These data and management information to achieve a variety of inquiries.
Theory and technology of the system is simple, easy system maintenance, and constantly updated. Therefore, this system is technically feasible. And that the system for less demanding operating environment, the general computer can run.
User interface design of the following three modules:
a. Station query module queries the route between any two sites
b. any trips trips query module queries the information
c. site query module information search any site of the trips
rar package contains the source code and release procedures, source code can be directly read using PowerBuilder 9.0, PowerBuilder 9.0 release does not nee

Description: 为提高基于内容的图像检索系统中纹理特征提取的有效性,提出了又一种纹理图像检索方法。该方法
利用非下采样 Contourlet变换对图像进行分解, 提取不同子带和不同方向变换系数矩阵的均值和方差为特征向量, 作
为数据库中纹理图像的索引,并利用两种不同的相似度函数计算图像之间的相似度,建立了一套基于示例查询图像
的纹理图像检索系统。实验结果表明,与小波包等特征提取方法相比, 该方法不仅能降低特征向量维数,而且能取得
更高的检索准确率和检索速度。-To i ncrease t he vali d ity o f tex t ure feature ex tracti on in conten t-based i mage retrieva l syste m, a nove l approach
