Vision-Based Recognition & Inference CPS

medicalCPS_FallDetection

Many efforts have been made to design classification systems that can aid the protection of elderly in a home environment. In this work, we focus on an accident that is a great risk for seniors living alone, a fall. Specifically, we present FADES, which uses skeletal joint information collected from a 3D depth camera to accurately classify different types of falls facing various directions from a single camera and distinguish an actual fall versus a fall-like activity, even in the presence of partially occluding objects …

smarthomeCPS_Kintense

Kintense is a robust, accurate, real-time, and evolving system for detecting aggressive actions such as hitting, kicking, pushing, and throwing from streaming 3D skeleton joint coordinates obtained from Kinect sensors. Kintense uses a combination of: (1) an array of supervised learners to recognize a predefined set of aggressive actions, (2) an unsupervised learner to discover new aggressive actions or refine existing actions, and (3) human feedback to reduce false alarms and to label potential …

smarthomeCPS_ChildSafe

In this work, we present ChildSafe, a classification system which exploits skeletal features collected for children and adults using a 3D depth camera to classify the visual characteristics between the two age groups.  ChildSafe analyses the histograms of training samples and implements a bin-boundary-based classifyer.  We train and evaluate ChildSafe using a large dataset of visual samples collected from 150 elementary school children and 43 adults, ranging in the ages of 7 and 50. Our results suggest that …

According to the United States Department of Health and Human Services, more than 3 million reports of child abuse are made in the nation, involving more than 6 million children. This is a huge issue not only in the U.S. but also all around the world, specifically in areas with a high children population such as daycare centers. While daycare centers are considered to be relatively safe, these environments present one of the biggest concerns against of safety of children. In this work, we focus on detecting …
