Albert Cohen (mathematician)
Albert Cohen (born June 29, 1965 in Paris ) is a French mathematician who studies wavelets and methods of image compression.
Cohen studied at the École polytechnique from 1984 to 1987 and received his doctorate in 1990 from the University of Paris IX (Dauphine) with Yves Meyer ( Wavelets, Multiresolution Analysis and Digital Signal Processing ). He was a post-doctoral student at Bell Laboratories in Murray Hill. In 1992 he completed his habilitation in Paris and from 1993 to 1995 was assistant professor at the École Nationale Supérieure de Techniques Avancées (ENSTA) in Paris. From 1995 he was professor at the Jacques Louis-Lions laboratory at the University of Paris VI (Pierre et Marie Curie).
With Ingrid Daubechies and Jean-Christophe Feauveau he developed Cohen-Daubechies-Feauveau wavelets (CDF wavelets), the first biorthogonal wavelets. They are used by the JPEG-2000 standard for image compression.
In 2000 he received the Prix Jacques Herbrand from the Académie des Sciences . In 1995 he received the VA Popov Prize in Approximation Theory and the Blaise Pascal Prize in 2004 and the Blaise Pascal Medal in 2020 . In 2002 he was invited speaker at the International Congress of Mathematicians in Beijing (Adaptive methods for PDEs: Wavelets or Mesh Refinement?).
