Description: 用Java实现的图像教学程序，涵盖大部分基本图像处理技术：（1）图像几何变换（图像翻转、旋转、缩放）；（2）色彩变换（灰度直方图，RGB->YSH变换，对比度调整，色彩增强，灰度均衡）；（3）卷积（锐化、柔化、边缘提取、中值滤波）；（4）频率变换（快速傅立叶fft，小波分解重构）-A teaching program which implements in Java. It includes most essential image processing technology.
1. Geometry Transform(Flip, Rotate, Scale)
2. Color Transform(Histogram, RGB-YSH Translate, Contrast, Level, Equalize in gray)
3. Convolve (Sharpness, Smooth , Edge enhancement, Mean)
4.Frequence Transform (FFT, wavelet reconstruct)
