Abstract:
1. A method for reconstructing an N-pixel image of a scene captured using a compressed sensing device, the method comprising: receiving a mask identifying at least one region of interest (ROI) of size Q pixels in the scene; arranging a set of M sampling functions in an M×N matrix φ={φ partitioning said set of sampling functions into K non-overlapping and non-empty subsets of functions, each subset having M arranging each resulting subset of functions in M modulating, by a spatial light modulator, incoming light according to a plurality of spatial patterns corresponding to said ordered sampling functions, said modulated light being focused onto a detector of a compressed sensing device; sampling, by said detector, sequential measurements of said modulated light focused thereon, each of said sampled measurements being an inner product result y reconstructing a spatial appearance of said scene from said sequence of projection coefficients after M inner products have been sampled, said reconstructed image being such that pixels associated with said ROIs have a higher image quality when rendered relative to other pixels in said image.
