Abstract: Wavelets have been described as the ultimate mathematical zoom. They've lead to countless research projects in signal processing: from geophysics to biomedical engineering. The FBI fingerprint standard has been based on wavelets for several years now. The wavelet-based JPEG2000 format may soon replace the Fourier-based JPEG format for lossy image compression.

We will give a brief overview on how to derive and understand some simple wavelets as well as how to do signal denoising or compression. If time allows, we will then proceed to answer some of the most popular questions including "which wavelet should I choose?" and "are wavelets better than Fourier?".

About the speaker: Daniel Lemire is a Research Officer at the National Research Council of Canada and an Adjunct Professor at the University of New Brunswick. He holds a Ph.D. in Engineering Mathematics from the École Polytechnique de Montréal as well as B.Sc. and M.Sc. from the University of Toronto. He has been the group leader of the NRC e-Health Research Group, a professor at Acadia University, an industry consultant, and a postdoctoral fellow at the Institut de génie biomédical. He applied wavelet techniques in geophysics, biomedical engineering, medical image compression, database acceleration, and Doppler signal analysis. He hosts the Wavelet Forum at: https://www.ondelette.com/indexen.html
