一种用于去除图像椒盐噪声的滤波算法

摘要

由于图像在获取、传输等过程中会受到各种噪声的影响，而在大多数应用中，又需要清晰的、高质量的图像，所以图像去噪是图像预处理中一项重要任务．图像中所含的噪声有很多种，椒盐噪声是其中最常见的一种．针对图像中所含的椒盐噪声，提出了一种改进的滤波去噪算法．实验结果表明，与其他常见滤波方法相比，改进算法简单有效．%Since image acquisition, transmission and other processes subject to various noise, and in most applications, but also need clear, high-quality images, so image denoising is an important task in image preprocessing. There are many kinds of noises in images, salt and pepper noise is the most common one. For salt and pepper noise contained in images, we proposed a modified filtering algorithms. The results showed that compared with other common filtering methods, this algorithm is simple and effective.
