In this paper, we introduced several noise removing techniques in the wavelet domain, analyzed the properties of bilateral filtering. Following them, bilateral filtering in the wavelet domain was proposed. With this method, the properties of time-frequency localization and multiresolution of wavelets were used. At last, we demonstrated the efficient noise removing and sharpening of object boundaries and detailed structures by applying this image processing technique to different images.
