在HSI空间中，采用自适应直方图均衡（AHE）方法实现了图像饱和度和亮度的调整，并进一步修正了图像的对比度。

Then, in HSI space, the method based on adaptive histogram equalization (AHE) is introduced to adjust the saturation and intensity. And then, the contrast is regulated further.

由于双边滤波的方法可以使滤波器的权系数随着图像的亮度变化而改变，所以在滤波过程中能达到自适应滤波的目的。

Since bilateral filtering method can make the weight coefficient of filter vary with image brightness, so the adaptive filtering effect can be attained during the filtering process.
