My research interests mainly concerned retrieval and management of information in the experimental field, particularly on data with low signal-to-noise ratio and/or low statistics. Cluster analysis, k-nearest neighbours, deconvolution algorithms, computational geometry, fuzzy set theory, mathematical morphology, Hough transform, are some of the tools adopted to define new not-standard methods of Pattern Recognition and Image Analysis in the application field of high-energy astrophysical data calibration and analysis.
