Hello! I'm Rogerio, a PhD student in the Department of Computer Science at University of California, Santa Barbara. My advisor is Prof. Matthew Turk. I received my BS degree in Computer Engineering from Federal University of Rio Grande (FURG); and my MS degree in Computer Science from University of Sao Paulo (IME-USP). My research interests are mostly concerned with Computer Vision, Graphics and HCI. I'm currently investigating novel methods for capturing and analysing discontinuities in vision and graphics applications. I'm also particularly interested in making computers aware of people through vision-based interfaces that analyze and model human faces, hands, body and gestures. As part of my work experience, I have the following summer jobs:

IBM Research - I worked with Ying-Li Tian (summer 2005) in the Exploratory Computer Vision Group , Hawthorne, New York (IBM T. J. Watson). Project: Multiview Face Detection for EC-ASSIST, a Darpa project involving IBM, Georgia Tech, MIT and UC-Irvine.

Mitsubishi Electric Research Labs - I worked with Dr. Ramesh Raskar at MERL in Cambridge, Massachussets. Project: A non-photorealistic ('NPR') camera, a self-contained device that makes use of a multi-flash technique to render cartoon-like, easy to understand images of complex scenes. 

Microsoft Research - I worked in the Media Presence group in San Francisco (Microsoft Bay Area Research Center) with Dr. Jim Gemmell and Dr. Kentaro Toyama. Project: GazeMaster, a videoconferencing system that uses computer vision and graphics methods to provide gaze awareness and sense of space.  Look at my Final Evaluation here.
