Biography

I am an Associate Professor in the Department of Computer Science at the Federal University of Minas Gerais, Brazil. My research interests include Computer Vision, Smart Surveillance, Forensics, and Biometrics, in which he authored more than 150 scientific papers and coordinates research projects sponsored by several Brazilian Funding Agencies, such as CNPq, FAPEMIG and CAPES, and R&D projects sponsored by large companies such as Samsung, Hewlett-Packard and Petrobras.

I am the head of the Smart Sense Laboratory, a laboratory that fosters research on large-scale Surveillance. The Smart Sense Laboratory is composed of researchers, graduate and undergraduate students that investigate problems related to Video Surveillance, Forensics and Biometrics by developing techniques on Computer Vision, Pattern Recognition and Digital Image Processing. The research group tackles problems including feature extraction, pedestrian detection, tracking and identification, spoofing detection, face recognition, person re-identification, multi-camera tracking, active cameras, processing of data captured by wearable devices, optimization of deep learning models, anomaly detection and activity recognition. The investigation of all these problems allows us to perform a better scene understanding.

Research

My research includes the development of techniques for Computer Vision, Machine Learning and Image Processing to solve problems on three main application domains: Smart Surveillance, Biometrics and Computer Forensics. I tend to investigate these problems in an integrated manner. While surveillance aims at “discovering” possible suspicious activities that can lead to an undesired event, the computer forensics searches for evidences once the event already took place in an earlier time. The biometrics is important for both because being able to identify the agents in the video might lead to different conclusions regarding the importance of the activities executed.

Research Group and Projects

My research group is in the Smart Sense Laboratory and is composed by researchers, graduate and undergraduate students focusing their works on Smart Surveillance, Forensics and Biometrics. The Smart Sense maintains a first class computational structure composed by several servers and multiple surveillance cameras that allow large-scale experiments. The group also maintains weekly meetings to discuss current papers, study technical books and share research updates among its members.

Over the years, I have coordinated several research projects in the areas of Computer Vision and Pattern Recognition applied to Smart Surveillance, Biometrics and Computer Forensics. Some of the projects have been sponsored by Brazilian Research Funding Agencies, such as the Brazilian National Research Council (CNPq), the Minas Gerais Research Foundation (FAPEMIG) and the Coordination for the Improvement of Higher Education Personnel (CAPES).

Besides the research projects, the group also conduct several R&D projects in partnership with large companies, those focusing on smart surveillance, video analytics and processing of signals captured by wearable devices. As an example of project it the creation and the development of a smart surveillance system in partnership with the Brazilian oil company (Petrobras) to alert the system operators regarding possible hazardous situations for the works in oil platforms, this project counts with a team of 19 researchers and staff. For more information regarding our P&D projects, please visit the laboratory website.

Currently, I am involved on projects focusing human activity recognition, human identification based on faces and tracking, detection of anomalies on videos, development of portable biometric devices, development of smart surveillance systems, video analytics, analysis of the vehicle cockpit, recognition of vehicles on road and the investigation of forensic-related problems.
