Robust Video Surveillance for Fall Detection Based on Human Shape Deformation
TL;DR: A new method is proposed to detect falls by analyzing human shape deformation during a video sequence, which gives very good results (as low as 0% error with a multi-camera setup) compared with other common image processing methods.
Proceedings ArticleDOI
Monocular 3D head tracking to detect falls of elderly people.
TL;DR: This work presents a new method to detect falls using a single camera based on the 3D trajectory of the head, which allows to distinguish falls from normal activities using 3D velocities.
Journal ArticleDOI

TL;DR: The living conditions of the elderly appear to influence their perception and receptivity regarding the acceptance and use of an IVS.
Journal ArticleDOI
3D head tracking for fall detection using a single calibrated camera
TL;DR: An original method to extract the 3D head trajectory of a person in a room is proposed using only one calibrated camera, represented as a 3D ellipsoid, which is tracked with a hierarchical particle filter based on color histograms and shape information.
Proceedings ArticleDOI
Video surveillance of medication intake.
TL;DR: In the context of the growing proportion of seniors in the western world population and the efforts provided in home care services, a computer vision system for monitoring medication intake is developed.
