• 2-D Wavelet-Based Spectra with Application in Analysis of Geophysical Images 

      Nicolis, Orietta; Garutti, Claudio; Vidakovic, Brani (Georgia Institute of Technology, 2006)
      We propose a wavelet-based spectral method for estimating the (directional) Hurst parameter in isotropic and anisotropic non-stationary fractional Gaussian fields. The method can be applied to self-similar images and, in ...
