摘要
为了比较自适应中值滤波相对于传统中值滤波在滤除数字图像中噪声时的优缺点,文章通过Matlab实现了中值滤波和自适应中值滤波仿真,分析了两种算法的滤波效果,从而从主观图像和客观参数上反映了自适应中值滤波算法的优越性,得到了它比传统中值滤波算法具有较好的图像去噪和细节保护性能的结论。
In order to compare the advantages and disadvantages of adaptive median filtering and the traditional median filtering in filtering out the noise in digital image, the simulation of both is achieved by Matlab. The effect of two algorithms is analyzed. The superiority of the adaptive median filtering algorithm is reflected subjectively and objectively. Aconclusion that the adaptive median filtering algorithm has a better image de-noising and detail preservation properties than traditional median filtering algorithm was obtained.
