srad（斑点抑制各向异性扩散滤波）

代码说明：

  图像滤波，SRAD.滤波的原理在于：信号或图像的能量大部分集中在幅度谱的低频和中频段是很常见的，而在较高频段，感兴趣的信息经常被噪声淹没，因此一个能降低高频成分幅度的滤波器就能够减弱噪声的影响。(The principle of image filtering and SRAD. filtering is that the energy of the signal or image is most common in the low frequency and middle frequency range of the amplitude spectrum. In the higher frequency section, the information of interest is often inundated by noise, so a filter that can reduce the amplitude of the high frequency component can weaken the influence of the noise.)
