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 average energy o…

Robust Wavelet-based Assessment of Scaling with Applications
Erin K. Hamilton, Seonghye Jeon, Pepa Ramirez Cobo +2
A number of approaches have dealt with statistical assessment of self-similarity, and many of those are based on multiscale concepts. Most rely on certain distributional assumption…
