WebA Gabor function is simply a sinusoid that has been windowed with a Gaussian. The frequency, orientation, and size of the function can be easily manipulated to produce a … WebA ridge theorem of the Gaussian chirp dictionary is proved, from which an estimate of the locally optimal scale and chirp is built. The procedure is restricted to a sub-dictionary of local maxima of the Gaussian Gabor dictionary to accelerate the pursuit further. The efficiency and speed of the method is demonstrated on a sound signal. 展开
