摘 要: 在文献[1]的基础上,提出几个改进的模糊加权平均滤波器。本文的方案不仅同时考虑了相邻像素对中心像素的兼容性以及中心像素对相邻像素的兼容性,而且还考虑到了权系数对局部环境的适应性。实验结果表明,该方法相比文献[1]中的模糊加权平均滤波器以及标准的均值滤波器、中值滤波器在噪声消除与边缘保留方面具有更好的性能。 We propose some modified fuzzy weighted filters based on reference[1]. Our scheme not only considers the compatibility of neighboring pixels with respect to the center pixel and the compatibi lity of the center pixel with respect to neighboring pixels at the same time, but also considers the adaptivity of the weighted coefficient according to the local environment. The experiment results show that this method is compared with those of other standard techniques in the respect of noise removal and edge preservation in the process of image smoothing.
