摘    要:提出了一种效果良好的基于去噪阈值的数字图像混合去噪算法。提出了模糊相邻度和去噪阈值的概念,采用加权平均来取代传统的绝对平均值,把相邻度设为像素的权值,把传统的点对点处用点对块处理来取代,采用去噪阈值取代传统的阈值,因而用所提出方法处理过的图像更加清晰。实验结果显示,该算法比基于传统平滑算法的去噪效果更佳。

关 键 词:数字图像  图像去噪  阈值  噪声度

Abstract:An efficient mixed de-nosing algorithm of digital image based on removed-nosie threshold is presented.The conception of neighborhood and removed-noise substituted for introduced.The weight average is substituted for traditional average operation,which is assigned as weight value.This algorithm also advances pixel-block operation instead of pixel-pixel operation and removed-noise threshold instead of segmentation threshold,which causes the image more explicit and shows obvious superiority especially when the...
