Claim 2:
3. The system of claim 1, wherein the at least one hardware processor is further programmed to:
generate, for each of the plurality of pixel locations, a set of photon transients including a photon transient associated with that pixel location and photon transients associated with neighboring pixel locations;
calculate, for each set of photon transients, a plurality of transform coefficients;
estimate, for each set of photon transients, a noise level based on a noise band and the plurality of transform coefficients calculated for that set of photon transients,
wherein the noise band is based on a profile of a light source used to generate the photon transients;

modify, for each set of photon transients, at least a subset of the plurality of transform coefficients based on the noise level, thereby generating a plurality of modified transform coefficients;
calculate, for each set of photon transients, an inverse transform using the plurality of modified transform coefficients associated with that set of photon transients,
wherein the inverse transform produces a set of modified photon transients;

generate, for each pixel location, photon flux estimates based on each modified photon transient associated with that pixel location.
