SUMMARY:Privacy-Preserving Localization and Recognition of Human  Activitie
 s
DESCRIPTION:Speaker: Prof. Janusz Konrad (Boston University\, USA)\n\nAbstr
 act: \nAbstract: Smart rooms\, that respond to occupant behavior\, will l
 ikely become a common occurrence in our lifetimes. With advanced sensors\
 , processors and algorithms\, such rooms are expected to save energy and 
 provide productivity as well as health benefits. Indoor localization of 
 occupants and recognition of their activities are two key components of t
 his vision. However\, traditional camera-based systems may not be accepta
 ble in privacy-sensitive scenarios since high-resolution images may revea
 l room details and occupant identity to eavesdroppers. I will first revie
 w traditional approaches to protecting occupant’s visual privacy\, incl
 uding reversible methods (e.g.\, data scrambling) and irreversible method
 s (e.g.\, optical and digital obfuscation of visual data). Then\, I will 
 describe computational solutions via resolution reduction recently develo
 ped at Boston University. In one approach\, a small network of ceiling-mo
 unted\, single-pixel RGB sensors collects visual data from which occupant
 ’s location is estimated by means of advanced algorithms. In another ap
 proach\, extremely low resolution videos (e.g.\, 16 x 12 pixels) are used
  to recognize occupant’s activities. Finally\, I will discuss visual pr
 ivacy protection by replacing the identity information in a person’s im
 age with another identity by means of variational generative-adversarial 
 networks (VGANs).\nBio: Janusz Konrad received Master’s degree from Tec
 hnical University of Szczecin\, Poland in 1980 and PhD degree from McGill
  University\, Montréal\, Canada in 1984. He joined INRS-Télécommunicat
 ions\, Montréal as a post-doctoral fellow and\, since 1992\, as a facult
 y member. Since 2000\, he has been on faculty at Boston University. He is
  an IEEE Fellow and a recipient of several IEEE and EURASIP Best Paper aw
 ards. He has been actively engaged in the IEEE Signal Processing Society 
 as a member of various boards and technical committees\, as well as an or
 ganizer of conferences. He has also been on editorial boards of various E
 URASIP journals. His research interests include video processing and comp
 uter vision\, stereoscopic and 3-D imaging and displays\, visual sensor 
 networks\, human-computer interfaces\, and cybersecurity.\n
