This report describes an implementation on the 3D-flow system developed at the Superconducting Super Collider Lab. of the algorithms and equipment to recognize valid photon events using a morphological analysis of the signals of an intensified CCD in the photon counting mode. The analysis consists of calculating the coordinates of a matrix corresponding to the exact position of each incident photon on the channel plate. Several off-line calculations with efficiency studies aiming at finding the best algorithm for event reconstruction have been performed. This off-line algorithm can be accomplished in real time at the CCD input rate (up to 2000 frames/sec). The communication-intensive nature of the algorithm and of the topology of this application and the particular architecture of the 3D-flow system lead to a very efficient implementation. The existing hardware simulator allows studies of the entire system before actual construction
