Contourlet-based image denoising algorithm using directional windows

合成孔径雷达SAR图像成像中多普勒中心检测的六种算法,使用matlab编程,-Synthetic aperture radar (SAR image of doppler center detection in six kinds of algorithm, using matlab programming,

主要是根据文章 Image smoothing via L0 gradient minimization中的算法编程得到的(Mainly in accordance with the article Image smoothing via L0 gradient minimization algorithm programming)

该算法是基于分裂Bregman的自适应总变分图像去噪算法，可以看到明显的图像去噪效果，也应该注意到总变分去噪的明显缺点。(The algorithm is based on split Bregman adaptive total variation image denoising algorithm, where you can see the obvious image denoising effect, and should also pay attention to the obviou
