"Graph signal processing and wavelet packets"Bulai, Iulia MartinaClassical wavelet, wavelet packets and time-frequency dictionaries have been generalized to the graph setting, the main goal being to obtain atoms which are jointly localized both in the vertex domain, the analogue of the time domain for signals on the real line, and the graph spectral domain, the analogue of the frequency domain. Here we present a new method to generate frames of wavelet packets defined in the graph spectral domain to represent signals on weighted graphs. |
