摘要
针对图像中的椒盐噪声,基于模糊理论设计了一种滤波算法。首先分析了椒盐噪声的特点,给出了自适应的噪声检测方法,并对噪点设计了自适应的噪声消除方法,最后采用几幅图像进行实验,定性和定量分析结果表明该方法对于椒盐噪声的消除可行、有效。
Aiming at salt ＆ pepper noise in images,a filter algorithm is proposed based on fuzzy theory in this paper. Firstly, the characteristics of the noise are analyzed, and an adaptive method of noise detection is presented, secondly, a method of removal is designed. The experimental results show that the proposed algorithm is effective and feasible for the salt ＆ pepper noise reduction.
