摘要
通过介绍一种易于实现的自适应权重中值滤波器(AWMF).该滤波器能根据局部图象的统计特征,调整中值滤波器的权重值,从而能在取得最大滤波效果的同时,还能很好地保持图象的细部特征.通过与均值滤波、中值滤波的对比实验,自适应权重中值滤波器表现出良好的滤波特性,而且它在抑制噪声的同时,较大限度地保持住图象的边沿特征.
The paper presents an easily applicable adaptive weighted median filter(AWMF).It can adjust weight coefficients based on the local image statistical characteristics,and make the use of median filter more efficient in the ideal noise suppression with negligible loss of genuine image details.By the comparative tests with the mean filter and the median filter,the AWMF performs best features in the reduction of noise and keeping edge information of images.
