From: From wavelets to adaptive approximations: time-frequency parametrization of EEG
A failure in feature extraction: MP decomposition of a signal consisting of two Gabor functions, both present in the dictionary used for decomposition. In the left column, from the top: slice of the time-frequency representation obtained from MP decomposition of the signal (R0) drawn below; R1--R3 are first three residues. First three time-frequency atoms (g 0--g 2) fitted by MP are shown in the right column
