Photon-Limited Image Detection Using Shot-Noise Models.
Abstract
The objective of this research continues to be the study of shot noise models and their application to the development of computationally feasible procedures for image detection problems. Also of interest is the performance evaluation of these procedures. These efforts are motivated by applications to low light level imaging as would occur in low dose x ray exposures or in night vision systems. Results are also be applicable to photon limited optical communication systems and to optical neural networks. Considerable progress has been made in understanding shot noise. The three major results of our research are (i) methods for computing shot noise distributions when both the intensity function and the system impulse response are known; (ii) methods for estimating an unknown intensity when only the impulse response is known; and (iii) methods for jointly estimating the intensity and the impulse response when both are unknown (a type of blind deconvolution).
