Pierre Portal, one of the ANU's most beloved math lecturers, is speaking for the CSSA's first academic event of the year.
Abstract: To efficiently store media digitally, we first acquire data and then apply a compression algorithm. This means that a large number of bytes is handled, but a substantially smaller number is actually stored. Wouldn't it be better to directly acquire the data that we are going to store? Until recently this tempting idea was considered impossible to implement. A turning point was reached in 2004, when progress in pure mathematics demonstrated that such compressed sensing was possible. Since then the mathematical ideas have been turned into technological advances, including a camera with one single pixel that can, through a small series of smart measurements, reconstruct a picture that would normally be acquired by a multi-million pixel camera. Through an introduction to signal processing in general, and compressed sensing in particular, I will talk about the role and nature of research in pure mathematics.
