这样，滤波时就可以考虑到图像的亮度信息，在滤除图像噪声的同时尽量保持了图像的边缘。

In this way, image brightness will be taken into account and the image edge should be simultaneously maintained as possible during filtering image noise.

实验结果表明，谊方法不但可以保持图像的边缘信息，而且能够提高去噪后图像的信噪比。

Experimental results showed that the algorithm could not only keep edge information of image, but also could improve signal-to-noise ratio of an image.

实验结果表明，该方法可以有效地抑制相干斑噪声，同时很好的保持边缘纹理信息。

Experimental results demonstrate that the proposed method can effectively suppress speckle noise, while preserving the edge and texture information.
