TAILIEUCHUNG - Robust watershed segmentation of noisy image using wavelet

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. | ISSN:2249-5789 Nilanjan Dey et al, International Journal of Computer Science & Communication Networks,Vol 1(2), 117-122 Robust Watershed Segmentation of Noisy Image Using Wavelet Nilanjan Dey1, Arpan Sinha2, Pranati Rakshit3 1 Asst.

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. This paper is organized as follows- Keywords— Wavelet, de-noising, Marker controlled Watershed Segmentation, Soft thresholding Section 2 describes Discrete wavelet transformation, Section 3 describes wavelet thresholding, Section 4 describes Wavelet based de-noising [1,2], Section 5 1. Introduction describes Marker controlled Watershed Segmentation, Image Segmentation is a technique to distinguish Section 6 describes experimental objects from its background and altering the image to a discussions, Section 7 Conclusion. results and much distinctive meaning and promoting easy analysis.
