The re-weighted M-estimator is bilateral filtering in natural.
在本质上，二次加权的M-估计器就是双向滤波器。
Simulation results prove that, compared with traditional bilateral filtering, the presented algorithm can remove noise and maintain image feature more effectively at the same time.
仿真实验表明，该算法相对一般双边滤波，能够在去除噪声的同时，更好地保持图像特征。
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.
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。
