Abstract :
An algorithm for the recognition of Cherenkov patterns based on the Hough Transform Method is presented. It basically consists in a mapping of the pad coordinate space directly to the Cherenkov angle parameter space with a crucial increase of performance in the treatment of different pattern shapes and amount of background.
thod has been developed in the framework of the ALICE experiment at CERN, for the analysis of data taken with the High Momentum Particle Identification Detector RICH prototype in the test beam.
