| 摘 要： | 中值滤波是一种简单而重要的处理椒盐噪声图像的方法,但传统的中值滤波只适用于弱噪声的情况,对于强椒盐噪声并不适用.本文在中值滤波的基础上,提出了一种自适应的二次中值滤波算法,该算法具有实现过程简单,运算复杂度低,自适应性强的特点.经过实验表明:该方法对强椒盐噪声图像具有良好的处理效果,特别适用于噪声大于50%的高强度椒盐噪声图像.

| Abstract: | Median filtering is a simple and important method for processing salt-and-pepper noise image,but the traditional median filtering is appropriate for the weak salt-and-pepper noise image,not for the strong.In this paper,a twice adaptive median filter algorithm is proposed on the basis of median filtering,which has a simple implementation,low complexity and a better adaptability characteristics.Experimental results demonstrate that the method has a good processing effect for strong salt-and-pepper noise image... |
