彩色图像混合滤波算法

Mixture Filtering Method for Color Image

提出了一种彩色图像混合滤波方法。该方法先判断像素的类型,然后用矢量加权均值滤波抑制高斯噪声,用多窗口矢量中值滤波抑制脉冲噪声。该算法能够自适应地选择滤波方法,提高了滤波性能。

A mixture filtering of the color image is proposed. There are two steps for this method. Firstly, the pixel type is judged. Then Gaussian noise is filtered by vector weighted mean filtering（VWMF）, and impulse noise is filtered by multi-window vector median filtering （MVMF）. The filtering method is adaptively selected, and the filtering performance is improved.
