Image Detection in Signal Dependent NoiseCunningham, D. R.; Laramore, R. D.; Barrett, E.; University of Missouri-Rolla; Missouri Engineering; ESL, Inc. (International Foundation for Telemetering, 1975-10)The detection of two dimensional optical signals which have been corrupted by noise is considered. Discussion is limited to the detection of a known object in a known location. The problem is approached from the classical statistical technique of hypothesis testing. Initially the solution is formulated in very general terms. The decision rule is derived for a signal distorted by noise of an unspecified type which may include signal dependent noise. Once the decision rule is obtained, the probabilities of false alarm and detection are evaluated from a priori knowledge of the noise and imaging system. The general results are applied to Poisson noise and signal dependent Gaussian noise.
