图像平滑主要是为了消除噪声。噪声并不限于人眼所能看的见的失真和变形，有些噪声只有在进行图像处理时才可以发现。图像的常见噪声主要有加性噪声、乘性噪声和量化噪声等。图像中的噪声往往和信号交织在一起，尤其是乘性噪声，如果平滑不当，就会使图像本身的细节如边界轮廓、线条等变的模糊不清，如何既平滑掉噪声有尽量保持图像细节，是图像平滑主要研究的任务。-image smoothing is mainly to eliminate noise. Noise is not confined to the human

针对合成孔径雷达(SAR) 图像含有大量斑点噪声的特点,基于Contourlet 的多尺度、局部化、方向性和各向
异性等优点,并结合隐马尔科夫树( HMT) 模型和隐马尔科夫场(MRF) ,提出了一种基于Contourlet 域持续性和聚

用不同的核进行图像的二维滤波
函数cvSmooth实现各种方法的图形平滑。
一般来说，图像平滑主要是为了消除噪声。图像的常见噪声主要有加性噪声、乘性噪声和量化噪声等。由于图像的能量主要集在低频部分，而噪声所在频段主要在高频段，因此通常都是采用低通滤波的方法消除噪声。
函数cvFilter2D对图像做卷积运算。
对图像进行线性滤波，支持替换方式操作。当核运算部份超出输入图像时，边界外面的像素值等于离它最近的图像像素值。
