Compressed Sensing Performance Bounds Under Poisson Noise
Compressed Sensing Performance Bounds Under Poisson Noise
This paper describes performance bounds for compressed sensing (CS) where the underlying sparse or compressible (sparsely approximable) signal is a vector of nonnegative intensities whose measurements are corrupted by Poisson noise. In this setting, standard CS techniques cannot be applied directly for several reasons. First, the usual signal-independent and/or bounded …
