自适应聚类滤波

Adaptive Cluster Filter

提出了一种新的用于图像平滑处理的滤波器自适应聚类滤波．它具有以下特点：（１）滤波器对像素点邻域内的灰度进行聚类，将聚类中心作为滤波器的输出；（２）滤波器能够根据像素点周围的拓扑特征，自适应地确定平滑窗口和窗口内平滑权重系数的大小，具有输入空间和输出空间两方面的自适应性．自适应聚类滤波用于图像的平滑处理，对滤除冲激噪声特别有效，同时较好地保持了边缘信息．

An adaptive smooth filter is proposed for image processing. It has two characters:(1)The output of the filter is regarded as the cluster center of nearby data.(2)It can adjust both the smooth window and smooth coefficients adaptively. The filter is especially useful for impulse noise, and it can preserve edge information well while removing noise effectively. The performance of the filter is proved by experiments.
