| 摘 要： | 文章提出了一种用于基于多级中值滤波的严重椒盐噪声污染图像恢复的方法.该算法首先用多级中值滤波对图像进行滤波,然后用噪声定位技术将滤波后的图像像素点分为噪声和信号点两类,建立噪声标记矩阵,进而对噪声点进行噪声消除,对非噪声点保持原值不变,从而实现噪声污染图像恢复.实验结果表明,本算法对于噪声浓度大于40%的污染图像去除噪声及保留细节等方面的效果非常显著,尤其对于严重椒盐噪声污染图像.

| Abstract: | A method based on multilevel median filter is presented for noise removal of an highly corrupted images by salt and pepper noise.At first,the method of multilevel median filter is applied,then the method of noise identify is implemented to classify each pixel to be signal pixel and noise pixel,and the noise labeling matrix is built.Based on the matrix,the noise pixel is removed,and the signal pixel is hold on.The experimental results show that the method has better behavior in noise removing and detail-pres... |
