| 摘 要： | 利用MTM滤波算法和灰色关联度的特点,提出一种基于MTM滤波算法和灰色关联度相结合的混合噪声图像的自适应滤波算法.算法选取加窗混合噪声图像的MTM值,采用灰色关联度自适应地计算各像素的加权系数,通过加权得到滤波后图像.仿真实验表明,该算法有较好的自适应性,不但能够有效抑制图像的噪声,而且能较好地保护图像的细节信息,提高图像的清晰度.

| Abstract: | In order to remove mixed noise in an image,Lee and Kassam proposed an improved algorithm of modified trimmed mean filter.Grey relevance can measure the degree of correlation among the levels of factor based on the factors similar to the system.Using the characteristics of MTM filter and grey relevancy,an algorithm for mixed noise filtering is presented based on MTM filter and grey relevance.A MTM pixel is determined in the filter window,and the coefficient of the proposed method can be varied adaptively bas... |
