This paper proposes an adaptive threshold estimation method for image denoising in the wavelet domain based on the generalized Guassian distribution (GGD) modeling of subband coefficients. The proposed method called NormalShrink is computat

Combined with PCA scale invariant feature transform (SIFT) algorithm, The true extent of the value of the intermediary measure, measure the true extent of the agency based on the value of image segmentation Using wavelet denoising thought.
