Abstract
Methods, systems and programs for denoising a signal using an undecimated discrete wavelet transformation are provided. The methods use signal location windows. The signal location windows may be used before or after thresholding. When signal location windows are used after thresholding coefficients within the signal location windows may be restored to their original values. When signal location windows are used before thresholding, coefficients within the signal location windows may be unchanged by the thresholding. The signal location windows may be used only on a subset of decomposition levels that are thresholded. The signal location windows may be used on both the Detail components and the highest decomposition level for thresholding of the Approximation component.
