In a multiview-imaging setting, image-acquisition costs could be substantially diminished if some of the cameras operate at a reduced quality. Compressed sensing is proposed to ef...

This is an attempt to simplify and justify the notions of deterministicand randomized reductions, an attempt to derive these notions from (more or less) rst principles.
