Title: Computer Vision Technologies and the Citizen: How massive visual sensing will change the way we "see" our selves. What the infrastructure sees, people can feel.
Bio: João Costeira is Associate Professor at IST and researcher of the Instituto de Sistemas e Robotica, where he served he served as deputy president (2014-2016) and coordinates the Signal and Image Processing (SIPg) since 2012. His research interests are in the area of visual recognition and 3D reconstruction from images. Jointly with CMU and IST, he holds a US/China patent request of a vehicle counting system from low resolution images, and was recipient of an unrestricted gift from Adobe Research Inc. in recognition for his contributions in the area. Since 2019 João Costeira integrated the H2020 project AI4EU that aims to create a European AI-on-demand platform and ecosystem, networking researchers companies and institutions at the European level. He is co-leader of the "Physical AI" task, which in cooperation with industry partners will develop AI tools for city-scale scale scenarios focusing on air quality assessment and control.
Title: Using computer vision to assess safety related behavior of road users – scaling data collection to regions and countries
Accurate knowledge of road users' safety-related behavior forms the basis of all evidence-based transport policy. Computer vision has been proposed as a tool for collecting behavioral data directly in the road system. But while relatively accurate methods for e.g. the detection of motorcycle helmets have been developed, they do not scale well, i.e. at location video data collection is still required. At the same time, large scale, crowd-sourced image data collected within the road system is readily available, but data quality varies substantially. We have developed a computer vision-based approach for efficiently processing large, crowd-sourced datasets, enabling region- and county-wide registration of road users’ safety related behaviors. For the example of motorcycle safety, our approach can generate highly accurate, location specific data on motorcycle helmet use and over-capacity riding, using a state-of-the-art computer vision algorithm. Data can be used to inform policy makers and road safety actors for legislation and education campaigns.
Bio: Felix Siebert is an Assistant Professor for transport psychology at the Department of Technology, Management and Economics at the Technical University of Denmark. His main research interest is the safety-related behavior of motorcyclists in low- and middle-income countries. Felix has conducted motorcycle helmet use studies in Indonesia, Madagascar, Myanmar, Nepal, and Tanzania with the WHO and local NGOs. More recently, he has applied computer vision for the automated detection of motorcycle helmet in video data.
