2D Anisotropic Wavelet Entropy with an Application to Earthquakes in Chile
MDPI (2015-06-16)We propose a wavelet-based approach to measure the Shannon entropy in the context of spatial point patterns. The method uses the fully anisotropic Morlet wavelet to estimate the energy distribution at different directions ... -
Wavelet-Based Entropy Measures to Characterize Two-Dimensional Fractional Brownian Fields
MDPI (2020-02-07)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 ...
