Linear-Quadratic Noise-Smoothing Filters for Quantum-Limited Images

Research output: Contribution to journalArticlepeer-review

9 Scopus citations


In this correspondence, we consider the use of nonlinear estimators for the noise smoothing of images obtained under quantum-limited imaging conditions. A Volterra expansion is investigated from which a set of linear-quadratic filters is derived using higher order statistics. The filters are applicable for single frame and multiple frames of a single scene imaged under low-light levels.
