| Abstract: | The princciples and methods of constructing wavelets based on Bubble function are investigated sys- tematically through coorperating the integral shifting basis of Gaussian functions and Bubble functions. Th wavelets with different lateral inhibitation propetis can be constructed by changing the shape parameter of Gaussian and Bubble functions. Some wavelets with lateral inhibition performnace can be incorporated into Bubble wavelets, or represental approximately by uses of a special Bubble wavelet. Finally, the coefficients of Mallat's pyramidal decomposition filter banks of a few special wavelets are given. |
