Abstract
In this correspondence, we consider the use of nonlinear estimators fo r 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 sing le scene imaged under low-light levels.
