Research Talk:  Illumination Invariant Face Recognition using Gamma Normalization and Sobel Edge Detection

Date:July 26, 2012 
Talk Title:Illumination Invariant Face Recognition using Gamma Normalization and Sobel Edge Detection
Speaker:Augusto Sarti, Associate Professor at Politecnico di Milano
Time & Location:12:00pm - 1:00pm
CIC Building, Pittsburgh


Geometry offers powerful tools of various degrees of complexity (from projective geometry to geometric algebra). Thanks to these tools it is possible to add depth to visual analysis, and improve the performance of monitoring systems of all sorts from face recognition systems, to visual forensic analysis solutions, to vision-based gesture recognition systems. 

What about sound and acoustics? What can geometry do for source acquisition, classification, recognition and monitoring in general? What can it do for acoustic scene reconstruction and related forensic applications?

In this talk I wil try to provide a crash overview of geometry-driven solutions for visual monitoring and offer a perspective on emerging geometric solutions for acoustic scene reconstruction and monitoring, from source localization, extraction and characterization to plenacoustic scene reconstruction.

Speaker Bio

Augusto Sarti received both the “Laurea” degree (masters level) and Ph.D. in Electrical and Electronic Engineering from the University of Padua, Italy, in 1988 and 1993, respectively, with research on nonlinear communication systems. His graduate studies included a joint graduate program with the University of California at Berkeley, CA, where he worked on nonlinear system theory.  In 1993 he joined the Politecnico di Milano, Italy, where he is currently an Associate Professor. His research interests are in the area of multimedia signal processing, with particular focus on space-time audio processing, sound analysis, synthesis and processing, music information processing, image analysis and 3D vision. 

He coauthored over 200 journal articles and papers on international congresses, and numerous patents in the image and sound processing area. He co-founded the Image and Sound Processing Group of the Politecnico di Milano, and two laboratories: the Sound and Music Computing Lab (Como Campus of the Politecnico di Milano) and the Image and Sound Processing Lab (Milano Leonardo Campus). He is currently coordinating the activities of the latter. He started a new master program in Sound and Music Engineering at the Politecnico di Milano (in collaboration with the Como Conservatory of Music).
