Bruno Aiazzi received the Laurea degree in electronic engineering from the University of Florence, Florence, Italy, in 1991. Since 2001, he has been a Researcher with the Institute of Applied Physics "Nello Carrara" (IFAC-CNR), which is located in the CNR Area di Ricerca di Firenze, Florence. He is currently Senior Researcher in the IFAC-CNR Institute. He has been working in several international research projects funded by the main European space agencies (ASI, ESA, CNES) on remote sensing topics: image quality definition and measurement, with applications to advanced hyperspectral sensors, adaptive methods for lossless and near-lossless data compression in satellite scenarios, multispectral and hyperspectral pansharpening algorithms, automatic estimation of multitemporal changes, and theoretical definition of statistic-based features for classification purposes. He is the coauthor of more than 30 papers published in international peer-reviewed journals, and a total of almost 200 publications. He is the recipient of the IEEE Geoscience and Remote Sensing Society Certificate of Appreciation as the winner of the 2006 Data Fusion Contest, Fusion on Multispectral and Panchromatic Images. He is an IEEE member. Stefano Baronti is Senior Researcher at the Institute of Applied Physics "Nello Carrara" (IFAC) of the National Research Council (CNR) of Italy. He was born in Florence, Italy, in 1954. He received the Laurea degree in Electronic Engineering from the University of Florence, in 1980 and joined CNR in 1985, as a Researcher of IFAC, where he is currently responsible for the research unit Systems, techniques, processing and analysis of multidimensional multiresolution remote sensing data. He has been involved in several projects funded by the Italian, French, and European Space Agencies. His research interests include computer vision applications, image compression, processing of optical and microwave remote sensing SAR images, and fusion and quality assessment of remote sensing data. He is the coauthor of more than 270 papers published in international peer-reviewed journals, proceedings of international conferences and book chapters. He is a member of the IEEE Geoscience and Remote Sensing Society (GRSS) and of the IEEE Signal Processing Society and participates in the GRSS Technical Committee on Data Fusion. He is the recipient of the IEEE GRSS 2004 Letter Prize Paper Award and the IEEE Geoscience and Remote Sensing Society Certificate of Appreciation as the winner of the 2006 Data Fusion Contest, Fusion on Multispectral and Panchromatic Images. Andrea Garzelli is Associate Professor of Telecommunications at the Department of Information Engineering of the University of Siena where he currently teaches the undergraduate and postgraduate courses on "Digital Signal Processing". He obtained the "Laurea" degree (summa cum laude) in Electronic Engineering and the Ph.D. degree in Computer Science and Telecommunication Engineering from the University of Florence, Italy, in 1991 and 1995, respectively. From 1995 to 2001 he has been Assistant Professor at the Department of Information Engineering of the University of Siena. He has been Program Coordinator of both graduate and Master degrees in Telecommunication Engineering at the University of Siena from 2002 to 2009. His research interests are in signal and image analysis, processing, and communication: nonlinear filtering, analysis of SAR images, and image classification and fusion for optical and SAR remote sensing applications. He is author of more than 150 scientific publications, including peer-reviewed journals, book chapters and conference proceedings. Dr. Garzelli is a Member of the IEEE Geoscience and Remote Sensing Society - Data Fusion Committee. He is the 2004 recipient, with his co-authors, of the IEEE Geoscience and Remote Sensing Society Letters Prize Paper Award for the paper "A Global Quality Measurement of Pan-Sharpened Multispectral Imagery". On January 2006, he has been elected Senior Member of the IEEE. He has been the invited speaker at the "Image and Signal Processing for Remote Sensing" Conference at SPIE Remote Sensing 2011 giving a talk on "Image sharpening: solutions and implementation issues."
