Target Classification Using Pyroelectric Infrared Sensors in Unattended Wild Ground Environment

Target Classification Using Pyroelectric Infrared Sensors in Unattended Wild Ground Environment

Pyroelectric Infrared (PIR) sensors are widely used as a simple presence trigger for alarms and a reliable counter for people in security home and smart office. Most paper have focused on the design and application of such systems, however, few research has be done on the detecting of targets in an outdoor environment using PIR sensors. In this paper, we realize a detecting system by means of P...

Detection and Classification for Unattended Ground Sensors

Seismic Target Classification Using a Wavelet Packet Manifold in Unattended Ground Sensors Systems

One of the most challenging problems in target classification is the extraction of a robust feature, which can effectively represent a specific type of targets. The use of seismic signals in unattended ground sensor (UGS) systems makes this problem more complicated, because the seismic target signal is non-stationary, geology-dependent and with high-dimensional feature space. This paper propose...

Abnormal Activity Detection Using Pyroelectric Infrared Sensors

Healthy aging is one of the most important social issues. In this paper, we propose a method for abnormal activity detection without any manual labeling of the training samples. By leveraging the Field of View (FOV) modulation, the spatio-temporal characteristic of human activity is encoded into low-dimension data stream generated by the ceiling-mounted Pyroelectric Infrared (PIR) sensors. The ...

Multi-Target Tracking with Unattended Ground Sensors (UGS) Data

This paper studies the performance of an Extended Kalman Filter/Multi-Hypothesis Tracking (EKF/MHT) approach to target tracking with data from seismic and acoustic sensors. We study the impact on tracking performance of the number, placement, and detection threshold associated with these sensors. Our algorithm scales well as the number of sensors increases, indicating its suitability for proces...
