Wavelet-Based Entropy Measures to Characterize Two-Dimensional Fractional Brownian Fields
The aim of this work was to extend the results of Perez et al. (Physica A (2006), 365 (2), 282−288) to the two-dimensional (2D) fractional Brownian field. In particular, we defined Shannon entropy using the wavelet spectrum from which the Hurst exponent is estimated by the regression of th...
