In this paper, we examine a simple dynamical feedback mechanism to separate objects from backgrounds in extremely low contrast/high noise imagery. The technique makes use of nonlinear time-delayed feedback to generate multiple gain states for individual pixels in an imaging array. These gain states can be manipulated to switch off background pixels and to switch on those pixels covering the signal of interest. The applicability of the technique to on-focal plane array processing is discussed and potential hardware limitations considered. © 2000 American Institute of Physics.
