Marco Leo received an Honours Degree in Computer Science Engineering from the University of Salento (Italy) in 2001. Currently he is a Researcher at the National Research Council of Italy. His main research interests are in the fields of image and signal processing and analysis, computer vision, pattern recognition, neural networks, graphical models, linear and non-linear transformation (Fourier, Wavelet, ICA, kernels functions). He participated in a number of national and international research projects focusing on assistive technologies, automatic video surveillance of indoor and outdoor environments, human attention monitoring, real-time event detection in sport contexts and non-destructive inspection of aircraft components. He is author of more than 100 papers in national and international journals, and conference proceedings. He is also a co-author of three international patents on visual systems for event detection in sport contexts. Giovanni Maria Farinella obtained a degree in Computer Science (egregia cum laude) from the University of Catania, Italy, in 2004. He joined as Internal Member of the IPLAB Research Group at University of Catania in 2005. He also became an Associate Member of the Computer Vision and Robotics Research Group at University of Cambridge in 2006. He was awarded a Doctor of Philosophy (Computer Vision) from the University of Catania in 2008. He is currently a Researcher at the Department of Mathematics and Computer Science, University of Catania, Italy. His research interests lie in the fields of Computer Vision, Image Analysis, Computer Graphics, Pattern Recognition and Machine Learning. Giovanni Maria Farinella founded (in 2006) and currently directs the International Computer Vision Summer School.
