基于幅度谱的椒盐噪声估计

Estimation of Salt & Pepper Noise on the Magnitude Spectrum

提出了一种基于幅度谱的椒盐噪声估计方法,该方法利用图像的幅度谱随椒盐噪声密度大小的变化规律,对图像中的椒盐噪声进行了估计。通过对大量含噪图像进行实验结果表明:该方法在对椒盐噪声密度中等和较高时效果较好。

A method which can estimate salt ＆ pepper noise based on the magnitude spectrum was proposed. It takes advantage of the reality that the magnitude spectrum changes with the density of salt ＆ pepper noise. The experiments on a wide variety of images indicate the method is effective when the density salt ＆ pepper is mediate and high.
