Description: 用途：数字图象处理算法的演示，包括：
• 图象的DFT和逆DFT
• 图象的FFT和逆FFT
• 在图象中加入正弦噪声
• 图象的模板运算实现图象平滑和锐化
• 图象的直方图均衡化
• 图象的对比度拉伸
• 图象的中值滤波
• 图象灰度直方图的显示
• 若干频域滤波器
• 图象的镜像
• 图象的旋转（90度与任意角度）
• 图象的放缩
• 其它小算法
代码设计思想：软件在Windows环境下，利用Visual C++6.0开发，代码利用面向对象的思想，通过若干个类完成：
主要类：
memBitmap类：内存图象类。将图象读入到内存中，对象素的读写在内存中进行，较之通过CDC类来进行，速度有很大提高。同时还对部分JPEG格式图象提供了读支持，可以将图象保存为BMP真彩格式。
Complex类：复数类，完成复数运算。
CBmpDemoView类：视类，完成显示。
CbmpDemoDoc类：文档类，图象数据和对数据的变换、处理都在此类中完成。
Fourior类：完成一维序列的DFT和FFT,FFT只支持为2的整数次幂的情况
