Conventional wavelet threshold denoising methods operate under the assumption that wavelet coefficients are independent, neglecting their correlations across adjacent scales, which results in an inherent trade-off between noise removal and preservation of useful high-frequency information.

By introducing the noise reduction concept of wavelet adjacent coefficient correlation into redundant second generation wavelets, this paper proposes a denoising method that overcomes the limitation of traditional threshold denoising methods which fail to consider correlations between wavelet coefficients. The implementation involves correlation analysis within wavelet coefficient neighborhoods and adaptive thresholding based on local statistical properties.
