Summary: In order to retain the edge information and remove the image noise as much as possible at the same time, a wavelet shrinkage algorithm was proposed, which took the inter-scale and intra-scale dependencies of wavelet coefficients into account. The proposed method used the correlation of wavelet coefficients and the average magnitudes of the surrounding wavelet coefficients within a local window to describe the inter-scale and intra-scale dependencies of wavelet coefficients, respectively. Thus, the image information and noise were identified. Meanwhile, a new threshold function was proposed to shrink wavelet coefficients. The experimental results show that the proposed denoising method can achieve high Peak Signal-to-Noise Ratio (PSNR).
