Abstract
Methods for visualizing wavelet spectra are considered for two realizations of fractal Brownian motion. The effect of “peak aggregation” on the energy density surface of a wavelet transformation is demonstrated using the local-scale normalization method. It is proposed that an adaptive scale of level lines based on the time-averaged distribution of the energy density of the wavelet transformation be used to eliminate the undesirable effect and to refine the image.
