| Research Abstract |
Wavelet frames in generalized Sobolev spaces were investigated.A wavelet frame design based on the Riesz potential was proposed. The proposed wavelet frame can decomposes functions or data into microlocal components. Quaternion valued Fourier and windowed Fourier transformations were investigated. An uncertainty principle was presented. A design of dictionaries for the sparse representation was proposed and its performances were numerically examined.
