1、实现直方图均衡算法。

2、实现局域变换增强。（平均平滑、高斯平滑、中指滤波）

3、实现真彩图像转换为灰度图像，实现伪彩色处理-1, the realization of histogram equalization algorithm.

2, to achieve local transformation enhanced. (average smoothing, Gauss smoothing, median filtering)

3, to achieve true color image is converted to grayscale images, the pseudo color processing
