Coeecient thresholding is a popular method in wavelet based noise reduction. A wavelet decomposition is typically a sparse representation of noise-free signals: the essential information is captured by a limited number of large, important coeecients, while the main part of coeecients is close to zero. Replacing these small coeecients by zero is a… CONTINUE READING
