This paper describes a method for person reidentification 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 discriminate(More)
Short- and long-term synaptic plasticity are considered to be cellular substrates of learning and memory. The mechanisms underlying synaptic plasticity especially with respect to morphology, however, are not known. In vitro conditioning in molluscan preparations is a well established form of short-term synaptic plasticity. Five paired presentations of light(More)
A new form of taste aversion conditioning was established in the pond snail Lymnaea stagnalis. An associative memory, lasting 24h, was produced in the pond snail with 20 pairings of 100 mM sucrose as the conditioned stimulus (CS) and mechanical stimulation to the head as the unconditioned stimulus (UCS). Animals exposed to reverse pairings of the CS and UCS(More)
Associative learning dependent on visual and vestibular sensory neurons and the underlying cellular mechanisms have been well characterized in Hermissenda but not yet in Lymnaea. Three days of conditioning with paired presentations of a light flash (conditional stimulus: CS) and orbital rotation (unconditional stimulus: UCS) in intact Lymnaea stagnalis(More)
We examined whether Ca(2+) induced Ca(2+) release through ryanodine receptors is involved in the conditioning of specific morphologic changes at the axon terminals of type B photoreceptors in the isolated circumesophageal ganglion of Hermissenda. Calcium chelation by bis(2-aminophenoxy) ethane-N,N,N',N'-tetraacetic acid prevented the conformational change(More)
Dynamics of changes in physiology and morphology were studied in Hermissenda photoreceptors after in vitro conditioning with paired light and vibration. An increase in input resistance of the type B photoreceptor was observed following 5 paired presentations of light and vibration. It peaked at 10 min after in vitro conditioning, then decreased to a level(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)
