Summary

Stéphane Mallat, mathematician and professor at the École Normale Supérieure de Paris, winner of the 2013 CNRS innovation medal, looks back on his research. He is one of the pioneers who introduced orthogonal wavelet bases and parsimonious representations. This theory has been applied in many scientific and industrial fields. In particular, he introduced wavelet image representation and compression algorithms, which led to the international JPEG-2000 standard. Stéphane Mallat subsequently developed the "strip" theory to optimize the coding of geometrically regular structures, in particular with applications for improving the quality of satellite and medical imaging. The exploitation of these mathematical algorithms gave rise to the start-up "Let It Wave" he directed.
