Abstract :
In this paper a novel approach to signal denoising in a wavelet domain is proposed. The signal is adapted to an a priori selected basis considering its details as the result of overlapping elementary atoms at different scale levels. This new proposal is supported by experimental observations along with some preliminary theoretical results.
