摘　　要：依据强度准则提出了基于强度准则的矢量中值滤波算法IVMF,保证了先识别噪声像素,再对噪声像素进行滤波,改善了传统矢量中值滤波算法运算量大、边缘模糊等问题。在此基础上,为了进一步改善滤波效率,采用矢量伪中值替代矢量中值,提出了基于强度准则的矢量伪中值滤波算法(IVPMF)。试验结果表明矢量伪中值滤波算法效率提高了近10%。The vector median filtering algorithm IVMF based on the strength criterion is proposed in the paper. It is to identify the noise pixel,then filter the noise pixel and it improves the traditional vector median filtering algorithm for large amount of computation and fuzzy edge problem. On this basis,vector pseudo median is used to replace vector median in order to further improve the filtering efficiency. The test results show that the efficiency of the pseudo vector median filtering algorithm is improved nearly 10%.
