Zheng Xiao-l · 2014
In recent yeas,the number of elderly people living along has grown rapidly.The safety issue is a problem that elderly residents must face,which not only reduce the quality of life,but also threat their lives.This paper proposed a real-time security monitoring solution which based on indoor temporal and spatial information.The method models the spatial and temporal data of historical activities to determine whether the current activity is abnormal.We collected the data by building the experimental platform and verified the effectiveness of the method we proposed in this paper by analyzing the experimental results.
