SUMMARY:Undersampling in physical imaging inverse problems - Bogdan Roman\

 ity of Cambridge

DESCRIPTION:Signal recovery from undersampled data is of great importance 
 to physical imaging systems. This talk will identify some intriguing asymp
 totic phenomena which can lead to improvements when carefully exploited. W
 e show that compressed sensing behaves differently at different resolution
 s and that this phenomenon can be exploited via sampling principles that a
 re aligned with the asymptotic phenomena\, applying them to various imagin
 g systems\, where it becomes possible to highlight higher length scales of
  interest in order to enhance image resolution and reveal more detail.
