Target Detection over the Diurnal Cycle Using a Multispectral Infrared Sensor

Sensors, 2016
When detecting a target over the diurnal cycle, a conventional infrared thermal sensor might lose the target due to the thermal crossover, which could happen at any time throughout the day when the infrared image contrast between target and background in

Improving Person Tracking Using an Inexpensive Thermal Infrared Sensor [PDF]

2014 IEEE Conference on Computer Vision and Pattern Recognition Workshops, 2014
This paper proposes a person tracking framework using a scanning low-resolution thermal infrared (IR) sensor colocated with a wide-angle RGB camera. The low temporal and spatial resolution of the low-cost IR sensor make it unable to track moving people and prone to false detections of stationary people.
