Nonextensive (Tsallis) and Generalized (Rényi) Entropies and Their Application to Signal and Noise Modelling in Wavelet Transform Space

We discuss the application of Tsallis or nonextensive entropy, as well as Shannon (Boltzmann-Gibbs-Shannon) entropy, to image retrieval. We also look at Rényi or generalized entropy in the context of signal modelling using Gaussian mixture models.In all cases we employ the wavelet transform.
