Claim 18:
19. A method for generating single-photon imaging data with improved signal-to-noise ratio, the method comprising:
generating, for each of a plurality of pixel locations, initial photon flux estimates based on a first set of photon transients including a photon transient associated with the pixel location and photon transients associated with neighboring pixel locations,
wherein each of the photon transients comprises a histogram of photon counts during a plurality of time bins at the pixel location;

identifying, for a scene patch associated with each of the plurality of pixel locations, one or more similar scene patches using intensity information for each of the plurality of pixel locations; and
generating, for each of the plurality of pixel locations, final photon flux estimates based on a second set of photon transients including photon transients associated with the scene patch and each of the one or more similar scene patches.
