该程序把数字图像处理与小波变换结合起来，可以出色地完成如图像对比度增强和图像融合等其他方法处理效果不佳的处理技术。-digital image processing and wavelet transform, integrate can be completed as excellent image contrast enhancement and image fusion, and other methods to deal with the effects of poor treatmen

先对图像均衡化 增强对比度 加噪声 然后分别进行空域和频域滤波-First, the contrast enhanced image equalization plus noise and then separate airspace and frequency domain filtering

直方图均衡化是一种最常见的间接对比度增强方法，通过使用累积函数对灰度值进行调整以实现对比度的增强。-Histogram equalization is one of the most common indirect contrast enhancement method by using the cumulative function of gray value " adjustment" in order to achieve contrast enhancement.
