摘要
提出了一种估计脉冲噪声强度的方法,并针对传统中值滤波(MF)法在去除脉冲噪声时存在的不足,给出了一种由噪声检测和噪声滤波2个阶段组成的图像滤波方法。实验结果表明,采用本文估计方法获得的噪声强度偏差较小,噪声滤波方法能在有效去除噪声的同时保持图像的边缘。
A method to estimate the impulse noise rate is proposed in this paper. At the same time, to overcome the shortcoming of traditional median filter,an image denoising algorithm composed of noise detection and noise filtering for impulse noise is researched. The computer simulation results indicate that it is accurate to estimate the noise rate by this method. Moreover,the noise filtering method is effective in denoising image and preserving the edge simultaneously.
