Continuous wavelet transform on the hyperboloid
Applied and Computational Harmonic Analysis, 2007 The main advantages of the known continuous wavelet transforms (CWT) over the classical Fourier transform are its local and multiresolution nature, which provide the properties of a mathematical microscope. However, data analysis has undergone deep changes recently and the field faces new exciting challenges. A given feature shared by these problems is
