Abstract:The wavelet de-noising approach is one of the most efficient techniques for noise reduction. Except for the mathematical elegancy in its theoretical aspect, a successful application requires appropriate determination on the decomposition level. This paper proposes a novel approach to selecting an appropriate decomposition level by applying the Gamma test on the noisy data to estimate the noise variance. A number of experiments were carried out on a set of smooth signals corrupted by white Gaussian noise to ver… Show more
