Activities 

Besides the regular paper sessions, there are three other activities to be held during AST2012. 

On the first day, Dr. Jacob Scharcanski, from Universidad Federal do Rio Grande do Sul, will present the conference “From Imaging Data to Useful Visual Information and Measurements”, sponsored by the IEEE Distinguished Lecturer Program.

In this talk, we address the problem of extracting relevant information from image data. We also introduce briefly the concepts and techniques often used in the automatic interpretation of phenomena based on imagery, or to make inferences based on models of such imagery data. When modeling and representing imaging measurements, usually we are trying to describe the world (or a real world phenomenon) using one or more images, and reconstruct some of its properties based on imagery data (like shape, texture or color). Actually, this is an ill-posed problem that humans can learn to solve effortlessly, but computer algorithms often are prone to errors. Nevertheless, in some cases computers can surpass humans and interpret imagery more accurately, given the proper choice of data representations (i.e. features), as we discuss in this talk. In order to illustrate this presentation, several applications are discussed, focusing in areas such as medicine, biometrics, pulp and paper, soil sciences, porous media, surveillance, and human-machine interfaces.

Jacob ScharcanskiJacob Scharcanski is an Associate Professor in Computer Science at the Federal University of Rio Grande do Sul (UFRGS), Brasil. He holds a cross appointment with the Department of Electrical Engineering at UFRGS, and also is an Associate Adjunct Professor with the Department of Systems Design Engineering, University of Waterloo, Ontario, Canada. He has authored and co-authored over 100 refereed journal and conference papers, and has contributed to several books on imaging and measurements. In addition to his academic publications, he has several technology transfers to the private sector. Presently, he serves as an Associate Editor for two journals, and has served on dozens of International Conference Committees. Professor Scharcanski is a licensed Professional Engineer, Senior Member of the IEEE, IEEE Multimedia Signal Processing TC Affiliate Member, and serves as Chair of the Technical Committee TC-17 (Materials in Measurements). His areas of expertise are Computer Vision, Imaging Measurements and their Applications.

 

The second day a Discussion Panel on the subject “New Network Technologies and Services” will be held. The panel will be composed by Ing. Marcelo Cohen: Senior Manager, Architecture & Technology Level 3, Latam. Specialized in Transmission optical networks (DWDM/SDH) and Metro Ethernet. Current postgraduate professor at UBA and ITBA.

Lic. Christian O’Flaherty: Regional Internet Development at Internet Society; promoting Internet access, growth, and sustainability in Latin American and the Caribbean. Formerly IP Technology Regional Manager at IMPSAT FIBER NETWORKS and Internet Operations Director at RETINA, Argentina National Academic Network.
