| 摘 要： | 在对图像中噪声模型分析的基础上,提出了一种基于剩余噪声检测的自适应中值滤波算法.通过对剩余脉冲的检测,自适应地改变滤波器窗口尺寸,从而有效地滤除密度较大的脉冲干扰,同时较好地保留图像的细节.对实际图像的测试结果表明,所提出算法的输出结果优于标准中值滤波器.

| Abstract: | After analyzing the noise pattern of the image,an adaptive median filter algorithm was proposed.By means of residual impulse noise detection,the window size of median filter was chosen adaptively to remove the high density impulse noise while preserving the details of the image.The experimental results indicate that the proposed algorithm is superior to the standard median filter in image quality and processing speed. |
