摘要
在光电成像应用领域中 ,有时会在图像上产生大量的正向脉冲噪声 ,严重地影响了图像质量。本文针对数字图像中出现的正向脉冲噪声 ,提出了基于行列处理消除正向脉冲噪声的非线性滤波器 (RCF) ,并分析了它的滤波和细节保护特性。通过对仿真图像的处理和应用实例 ,与几种非线性滤波器做了对比。实验表明基于行列处理的非线性滤波器通过简单的行列处理 ,不但能有效消除正向脉冲噪声 ,而且对图像边缘和细节具有较强的保护能力。
Amountof positive impulse noise on images may be caused in the field of photo- electronic imaging.It degenerates the images seriously.In order to remove the positive impulse noise,a nonlinear filter(RCF) based on row and column filtering is presented and its filtering and detail protection properties are analyzed in the pa- per.The nonlinear filter is compared with other nonlinear filters through the simulation and actual application. It is shown that the filter presented in the paper has the ability of effective removing the positive impulse noise and better protection for edges and details with simple row and column processing.
