dc.descriptionWe propose an automated method for detecting galaxy clusters in imaging surveys based on the Voronoi tessellation technique. It appears very promising, expecially for its capability of detecting clusters indipendently from their shape. After a brief explanation of our use of the algorithm, we show here an example of application based on a strip of the ESP Key Programme complemented with galaxies of the COSMOS/UKST Southern Sky Catalogue supplied by the Anglo- Australian Observatory.
