The representation of data in terms of its statistical properties is valuable in many applications. This work uses statistics obtained from 4D scene geometry to characterize, in terms of redundancy, the content produced by lenslet-based light field cameras and by high-density arrays of cameras for the JPEG Pleno Call for Proposals on Light Field Coding. This paper proposes a novel so-called geometric...
Compressive Sensing (CS) allows for reconstructing sparse signals within a low acceptable error using less measurements than stipulated by the Nyquist criterion. This CS paradigm rests on the assumption that there is a basis in which the signal is sparse, and one employs random measurements by means of projections on a sensing matrix reconstructing the signal from these measurements through l1-norm...
