WaveletThreshold

WaveletThreshold[dwd] thresholds the detail wavelet coefficients in the DiscreteWaveletData object dwd.

• WaveletThreshold[dwd, tspec] thresholds the coefficients using the thresholding specification tspec.
• WaveletThreshold[dwd, tspec, wind] thresholds the wavelet coefficients given by the wavelet indices wind.

Examples

data = {1, 2, 3, 4, 5, 6, 7, 8};
dwd = DiscreteWaveletTransform[data];
WaveletThreshold[dwd]
