Pattern recognition and beyond: Alfredo Petrosino's scientific results

We summarize the main scientific contributions of our friend and colleague Alfredo Petrosino, full professor in computer science at the University of Naples Parthenope, Italy. They mainly cover topics in high-performance computing, neural network models, soft and granular computing, computer vision, and machine learning. We also highlight how most of his research activity lays the foundation for biometry and its applications.
