摘　　要：本文针对自适应中值滤波算法对高密度固定值脉冲噪声去噪效果欠佳的缺陷,提出一种扩大窗口时利用上次滤波结果的迭代方法,同时为了提高去噪效果,将最大滤波窗口调整至9×9。通过仿真分析,相比于现有的自适应中值滤波算法,新算法的去噪效果得到明显提高。This paper proposes an iterative method that uses the previous filter results when expanding the window to address the shortcomings of the adaptive median filter algorithm’s poor denoising effect on high-density fixed-value impulse noise.At the same time,in order to improve the denoising effect,the maximum filter window is adjusted to 9×9.Through simulation analysis,compared with the existing adaptive median filter algorithm,the denoising effect of the new algorithm has been significantly improved.
