本文提出了一种基于噪声检测的迭代中值滤波算法。该算法首先检测出噪声点，然后利用信号点对噪声点滤波。其中，噪声检测方法改进了Minmax方法。经过实验仿真并与其他滤波算法进行比较表明，该算法可以有效地去除图像中的脉冲噪声并且保留原图像的细节。

A New Median Filtering Algorithm Based on Noise Detection

An iterative median filtering algorithm based on improved noise detection for the removal of impulse noises from the images is presented. The algorithm detects the corrupted pixels first and filters the corrupted pixels using the noise-free pixels.The noise detection strategy improves the Minmax technique.Simulation results demonstrate that this algorithm is superior to other existing median-based filtering algorithms,and is effective in noise suppression and detail preservation.
