NUFFT, Discontinuous Fast Fourier Transform, and Some Applications

Dr. Qing Liu

Department of Electrical and Computer Engineering at Duke University

Abstract:   Over the last decade, there have been significant interests in the development of fast Fourier transform algorithms for nonuniformly sampled data because of many practical applications. In this talk, I will review our work on the nonuniform fast Fourier transform (NUFFT) and discontinuous fast Fourier transform for singular functions. I will then present some applications in the numerical solution of wave equations and in subsurface and biomedical image reconstruction.
