William Schwartz
Associate Professor in the Department of Computer Science at the Federal University of Minas Gerais, Brazil
I am the head of the Smart Sense, a research group that investigates problems related to Video Surveillance, Forensics and Biometrics by developing techniques on Computer Vision, Pattern Recognition and Digital Image Processing. The Smart Sense research group is located at the Uncertainty in Artificial Intelligence Laboratory (LabUAI) which is composed of researchers, graduate and undergraduate students.
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.
Projects
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.
Publications
I published many scientific papers focusing on computer vision, smart surveillance, biometrics and computer forensics in important conferences and journals, such as ICCV, ECCV, BMVC, WACV, ICIP, ICASSP, FG, IEEE Transactions on Image Processing, IEEE Transactions on Information Forensics and Security, Elsevier Neurocomputing and a book on Image Processing.

Sense-ALPR Database
This dataset, called the Sense-ALPR Database, was created to assist researchers in evaluating automatic license plate recognition problems. The data for the article Real-Time Automatic License Plate Recognition Through Multi-Task Networks was captured during the day using two cameras: one placed statically while recording passing vehicles and another placed inside of a vehicle that registered as the vehicle moved through the city.
