摘　　要：文章提出一种新的快速矢量中值滤波算法。首先,求取象素的方向区域距离测度并将滤波窗口划分为两个子窗口;然后,在子窗口内进行矢量中值滤波。实验结果表明,该算法速度快,具有较好的滤波效果。A new fast vector median filtering algorithm is proposed.Firstly,the direction region distance measure of the pixel is computed and its filtering window is divided into two sub- window in a color image,then,the vector median filtering algorithm is executed in a sub- window.The experimental results show that the proposed algorithm can remove impulse noise and its computation speed is much faster than the classical Vector median filtering algorithm.
