Sensing movement and activity through first person vision

Recent progress in miniaturizing digital cameras and improving battery life has created a growing market for wearable cameras, exemplified by products such as GoPro and Google Glass. The imagery captured by these cameras is a unique video modality which implicitly encodes the attention, movement, and intentions of the user. The analysis of such video through First-Person Vision (FPV) provides new opportunities to model and analyze human behavior, create personalized records of visual experiences, and improve our understanding and treatment of a broad range of mental and physical health conditions. This talk will describe current research progress in First Person Vision, with a specific focus on measuring aspects of human movement and activity. It will describe the unique properties of first person video and describe some preliminary work on from our group and others on the use of robot localization algorithms (i.e. SLAM) to measure human movement during daily life. We will also describe progress in automatically recognizing activities of daily living from FPV in a home environment. This is joint work with Drs. Agata Rozga, Maithilee Kunda, Alireza Fathi, and Ph.D. students Yin Li and Alicia Bargar.

Rehg (pronounced “ray”) is a Professor in the School of Interactive Computing at the Georgia Institute of Technology, where he is Director of the Center for Behavioral Imaging and co-Director of the Computational Perception Lab (CPL). He received his Ph.D. from CMU in 1995 and worked at the Cambridge Research Lab of DEC (and then Compaq) from 1995-2001, where he managed the computer vision research group. He received an NSF CAREER award in 2001 and a Raytheon Faculty Fellowship from Georgia Tech in 2005. He and his students have received best student paper awards at ICML 2005, BMVC 2010, Mobihealth 2014, and Face and Gesture 2015, and a 2013 Method of the Year Award from the journal Nature Methods. Dr. Rehg serves on the Editorial Board of the Intl. J. of Computer Vision, and he served as the Program co-Chair for ACCV 2012 and General co-Chair for CVPR 2009, and will serve as Program co-Chair for CVPR 2017. He has authored more than 100 peer-reviewed scientific papers and holds 25 issued US patents. His research interests include computer vision, machine learning, robot perception and mobile health. Dr. Rehg was the lead PI on an NSF Expedition to develop the science and technology of Behavioral Imaging, the measurement and analysis of social and communicative behavior using multi-modal sensing, with applications to developmental disorders such as autism. He is currently the Deputy Director of the NIH Center of Excellence on Mobile Sensor Data-to-Knowledge (MD2K), which is developing novel on-body sensing and predictive analytics for improving health outcomes.
