一种新的高密度椒盐噪声滤波算法
A Novel Filtering Algorithm of High Density Salt and Pepper Noise
摘要
Abstract
Aiming at drawbacks of the poor de-noising capacity for high-density noised images, a novel filtering algorithm of high density salt and pepper noise is proposed in this paper. The algorithm is adopted to separate the pixels in the image into signal pixels and noise pixels. It calculates the median value of the non salt and pepper pixels in the window centered at the current salt and pepper pixel, while signal pixels hold their gray values and be output unprocessed. The steps above are repeated until there is no noise replaced. Experimental results show that the algorithm can suppress noise effectively and preserve the image details. Contrasted to the traditional median filtering algorithm and its improved algorithms, it has better filtering performance.关键词
