Mel endpoint detection performance evaluation after applying various noise reduction methods in speech signal processing, with MATLAB code implementation details

Neighborhood Correlation-Based Redundant Second Generation Wavelet Denoising Method

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.
