The invention relates to the technical field of digital image processing, in particular to a switch weighting vector median filter method utilizing edge detection. The switch weighting vector median filter method improves noise reduction capacity vector median filter, and protects image details. According to the technical scheme, the switch weighting vector median filter method comprises the following steps that the similarity of pixel points in a noise image are compared with that of the corresponding pixel points in a reference image obtained through scalar median filter which is carried out on R, G and B components of the noise image, so that noise monitoring is carried out, vector median filter is carried out on suspected noise points through the weighting method based on edge detection, the noise reduction capacity of vector median filter is improved, and the image tails are protected. The switch weighting vector median filter method is mainly applied to digital image processing.
