Alexandre Xavier Falcão
University of Campinas, Brazil



Alexandre Xavier Falcao is full professor at the Institute of Computing (IC), University of Campinas (Unicamp). He currently holds a research productivity fellowship (level 1B) from the Brazilian National Council for Scientific and Technological Development (CNPq) and serves as Senior Area Editor of the IEEE Signal Processing Letters, coordinator of the Computer Science area at FAPESP, member of the editorial board of the journal Computer Methods in Biomechanics and Biomedical Engineering: Imaging & Visualization, and as member of the program committee of several conferences (e.g., SPIE on Medical Imaging and SIBGRAPI).

He received a B.Sc. in Electrical Engineering from the Federal University of Pernambuco in 1988, and has worked in biomedical image processing, visualization and analysis since 1991. In 1993, he received a M.Sc. in Electrical Engineering from the University of Campinas. During 1994-1996, he worked with the Medical Image Processing Group at the Department of Radiology, University of Pennsylvania, USA, on interactive image segmentation for his doctorate. He got his doctorate in Electrical Engineering from the University of Campinas in 1996. In 1997, he worked in a project for Globo TV at a research center, CPqD-TELEBRAS in Campinas, developing methods for video quality assessment.

His experience as professor of Computer Science and Engineering started in 1998 at Unicamp. At IC-Unicamp, he was Associate Director (2006-2007) and Coordinator of the Post-Graduation Program (2009-2011). In 2011-2012, he spent one-year sabbatical at the Robert W. Holley Center for Agriculture and Health (USDA, Cornell University), EUA, working on image analysis applied to plant biology.

He has research productivity fellowships from CNPq since 1998. Among several awards, it is worth mentioning two Unicamp inventor awards at the category "License Technology" (2011 and 2012), three awards of academic excellence (2006, 2011, 2016) from IC-Unicamp, one award of academic recognition "Zeferino Vaz" from Unicamp (2014), and one the best paper award in the year of 2012 from the journal Pattern Recognition (received at Stockholm, Sweden, during the conference ICPR 2014).

His research work aims at computational models to learn and interpret the semantic content of images in the domain of several applications. His research interests include image/video processing, visualization, and analysis; graph algorithms and dynamic programming; image annotation, organization, and retrieval; machine learning and pattern recognition; and image analysis applications in Biology, Medicine, Biometrics, Geology, and Agriculture.

Longin Jan Latecki
Temple University, USA



Dr. Longin Jan Latecki is a professor of computer science at Temple University, Philadelphia. His main research interests include shape representation and similarity, object detection and recognition in images, robot perception, machine learning, and digital geometry. He received his PhD degree in 1992 and the habilitation in 1996, both from University of Hamburg, Germany. He has published over 250 research papers and books (h-index = 46). He is an editorial board member of journals Pattern Recognition and Computer Vision and Image Understanding. He received 2010 College of Science and Technology Research Excellence Award at Temple University, the annual Pattern Recognition Society Award together with Azriel Rosenfeld for the best article published in the journal Pattern Recognition in 1998. He is also the recipient of the 2000 Olympus Prize, the main annual award, from the German Society for Pattern Recognition (DAGM).

János Pach
EPFL, Switzerland


János Pach is Chair of Combinatorial Geometry at EPFL, Lausanne and Research Adviser at Rényi Institute, Budapest. His main fields of interest are discrete and computational geometry, convexity, and combinatorics. He wrote more than 300 research papers. His books, ``Research Problems in Discrete Geometry'' (with Brass and Moser) and ``Combinatorial Geometry" (with Agarwal) were translated into Japanese, Russian, and Chinese. He is co-editor-in-chief of Discrete & Computational Geometry and serves on the editorial boards of ten other professional journals. For his scientific achievements, he received several prices, including the Lester R. Ford Award from the Mathematical Association of America (1990), the Rényi Prize and the Academy Award from the Hungarian Academy of Sciences (1993, 1998). He was elected ACM Fellow (2011), member of Academia Europeae (2014), and AMS Fellow (2015). He was invited speaker at the International Congress of Mathematicians in Soeul (2014).


Workshop on Discrete Topology and Mathematical Morphology, in honor of the retirement of Gilles Bertrand

Tat Yung Kong
City University of New York, USA


T. Yung Kong is Professor of Computer Science at Queens College of the City University of New York. Much of his published work has dealt with topological problems relating to binary images, especially problems of digital topology. He has also worked on some topics in other research areas (such as the theory of fuzzy segmentation and algorithms for convex feasibility in recent years). A member of the Computer Science faculty at Queens College since 1989, he previously held faculty positions in computer science at Ohio University and in mathematics at City College of the City University of New York. In 2000-01 he was a Visiting Professor in the Computer and Information Sciences Department at Temple University. He has a B.A. in mathematics and an M.Math. from the University of Cambridge (earned in 1981 and 1982). In 1982-85 he was a doctoral student at the Oxford University Computing Laboratory, where he pursued research on digital topology. He received a D.Phil. from the University of Oxford in 1986.


Philippe Salembier
Universitat Politècnica de Catalunya, Spain


Philippe Salembier received an engineering degree from the Ecole Polytechnique, Paris, France, in 1983 and an engineering degree from the Ecole Nationale Supérieure des Télécommunications, Paris, France, in 1985. From 1985 to 1989, he worked at Laboratoires d'Electronique Philips, Limeil-Brevannes, France, in the fields of digital communications and signal processing for HDTV. In 1989, he joined the Signal Processing Laboratory of the Swiss Federal Institute of Technology in Lausanne, Switzerland, to work on image processing and received a PhD in 1991.
