Abstract
Color impulse noise removing is a hot research problem in digital image processing, vector median filter (VMF) is a kind of traditional highly effective vector filter for color impulse noise removing. But it fails to distinguish details edges from impulsive noise, and usually filter them out. A novel vector median filter is proposed in this paper. This method uses quaternion rotation theory and the principle of Laplacian operators to construct the new switching condition. Combining this color impulse detector with the traditional VMF and some of the representative vector filters and recently developed vector filters, the proposed filters not only effectively preserves the edge details, but also provides better filtering performance.
