Theory of Operation¶
Introduction¶
The centroids, photon finding routines work through the following principles. Initially, the code makes a first pass through each image pixel by pixel looking for potential photon events. This search algorithm is described in Initial Pass Through Image. Once each image has been searched, and a list of potential events found, the code then processes each potential photon in turn.
The second pass, described in Second Pass Through Photons evaluates each potential photon event applying a number of filters to determine if the event is a true photon. If the event is determined to be a photon, then the code performs calculations on the photon, storing the values in a final list.
