Natural images often get corrupted by noise during acquisition and transmission. Segmentation of these noisy images does not provide desired results, hence de-noising is required. In this paper, we tried to address a very effective technique called Wavelet thresholding for denoising, as it can arrest the energy of a signal in few energy transform values, followed by Marker controlled Watershed Segmentation. advantage of multi-resolution and multi-scale gradient of the most conventional ways of image de-noising is using filters. Wavelet thresholding approach gives a very good result for the same. Wavelet Transformation has its own excellent spacefrequency localization property and thresholding removes coefficients that are inconsiderably relative to some threshold.
