This paper describes a method for person re-identification across multiple non-overlapping cameras using both gait and color features. Because a single color feature is insufficient to distinguish persons with similar color clothes, a spatio-temporal histogram of oriented gradients is employed as a gradient-based shape and motion gait feature to(More)
In cold climates, the high heat demand during winter calls for an especial attention on the development of new generation systems with low impact on the environment. Due to this, the development of a clean CO<sub>2</sub> hydrate generation system which operates utilizing the expansion characteristics of the CO<sub>2</sub> hydrate without burning any type of(More)
We demonstrate a privacy-conscious system for human tracking. This system can locate persons without any wearable device. The system detects their footprints by applying near-field tag antenna based sensing (NF-TABS) technology which uses passive radio-frequency identification (RFID) tags as sensors [1] [2]. And the system uses other RFID tags to recognize(More)
