摘　　要：该文提出了一种用于抑制椒盐噪声的多窗口中值滤波算法。算法在执行过程中根据具体情况采用不同大小的滤波窗口。仿真结果表明,与标准中值滤波算法相比,该方法不仅可以有效去除图像中的椒盐噪声,特别是在噪声密度非常大的情况下,表现了很好的性能。A new kind of median-based filtering algorithm-multi-window adaptive filtering is given to restore images corrupted by salt-pepper impulse noise. The size of the filtering windows is variable in the operation. Simulation results demonstrate that this algorithm is better than traditional median-based filters and particularly effective for the cases where the images are very highly corrupted.
