Abstract As a new tool, the wavelet transform has been used successfully in signal denoising. In this paper, the MAP estimate of double Haar wavelet transform coefficients is developed. Also, its application to image denoising is discussed. Examples show that the proposed approach is better than the soft thresholding in image denoising.
