  • Abstract
    In this study we present a denoising scheme applied to a non-orthogonal wavelet transform and compare the performances obtained with those based on orthogonal decompositions. We investigate the effect due to small sample sizes, specific thresholding levels, and initial thresholding scales, and compare results obtained for orthogonal and non-orthogonal transforms.
