The Dual Wavelet Spectra: An Alternative Perspective on Hurst Exponent Estimation with Application to Mammogram Classification

Raymond J. Hinton, Pepa Ramírez Cobo, Brani Vidakovic

The wavelet spectra is a common starting point for estimating the Hurst exponent of a self-similar signal using wavelet-based techniques. The decay of the ${\log }_2$ average energy o…
