Abstract—In this paper we proposed a new approach for color Image denoising using wavelet thresholding. The denoising process rejects noise by thresholding in the wavelet domain.Wavelet analysis is powerful tool for Image Denoising when Image are to be viewed or processed at multiple resolution Wavelet Transform is the mathematical tool for denoising. Discrete wavelet transform has the benefit of giving a joint time frequency representation of the signal. Also it is suitable for both stationary and non-stationary signals and is the most appropriate System in the field of signal detection. Discrete wavelet transform is implemented through multi resolution an alysis and digital filter banks. The proposed method was applied by using MATLAB R2013a with color images contaminated by white Gaussian noise.
