Traffic-Aware Multi-Camera Tracking of Vehicles Based on ReID and Camera Link Model

Multi-target multi-camera tracking (MTMCT), i.e., tracking multiple targets across multiple cameras, is a crucial technique for smart city applications. In this paper, we propose an effective and reliable MTMCT framework for vehicles, which consists of a traffic-aware single camera tracking (TSCT) algorithm, a trajectory-based camera link model (CLM) for vehicle re-identification (ReID), and a hierarchical clustering algorithm to obtain the cross camera vehicle trajectories. First, the TSCT, which jointly considers vehicle appearance, geometric features, and some common traffic scenarios, is proposed to track the vehicles in each camera separately. Second, the trajectory-based CLM is adopted to facilitate the relationship between each pair of adjacently connected cameras and add spatio-temporal constraints for the subsequent vehicle ReID with temporal attention. Third, the hierarchical clustering algorithm is used to merge the vehicle trajectories among all the cameras to obtain the final MTMCT results. Our proposed MTMCT is evaluated on the CityFlow dataset and achieves a new state-of-the-art performance with IDF1 of 74.93%.Comment: Accepted by ACM International Conference on Multimedia 202

Expert-Novice Differences in SMR Activity during Dart Throwing

Cheng M-Y, Hung C-L, Huang C-J, et al. Expert-Novice Differences in SMR Activity during Dart Throwing. Biological Psychology. 2015;110:212-218.Previous evidence suggests that augmented sensorimotor rhythm (SMR) activity is related to the superior regulation of processing cognitive-motor information in motor performance. However, no published studies have examined the relationship between SMR and performance in precision sports; thus, this study examined the relationship between SMR activity and the level of skilled performance in tasks requiring high levels of attention (e.g., dart throwing). We hypothesized that skilled performance would be associated with higher SMR activity. Fourteen dart-throwing experts and eleven novices were recruited. Participants were requested to perform 60 dart throws while EEG was recorded. The 2 (Group: Expert, Novice) x 2 (Time window: –2000 ms to –1000 ms, –1000 ms to 0 ms) ANOVA showed that the dart-throwing experts maintained a relatively higher SMR power than the novices before dart release. These results suggest that SMR might reflect the adaptive regulation of cognitive-motor processing during the preparatory period

Sensorimotor Rhythm Neurofeedback Enhances Golf Putting Performance

Cheng M-Y, Huang C-J, Chang Y-K, Koester D, Schack T, Hung T-M. Sensorimotor Rhythm Neurofeedback Enhances Golf Putting Performance. Journal of Sport & Exercise Psychology. 2015;37(6):626-636.Sensorimotor rhythm (SMR) activity has been related to automaticity during skilled action execution. However, few studies have bridged the causal link between SMR activity and sports performance. This study investigated the effect of SMR neurofeedback training (SMR NFT) on golf putting performance. We hypothesized that preelite golfers would exhibit enhanced putting performance after SMR NFT. Sixteen preelite golfers were recruited and randomly assigned into either an SMR or a control group. Participants were asked to perform putting while electroencephalogram (EEG) was recorded, both before and after intervention. Our results showed that the SMR group performed more accurately when putting and exhibited greater SMR power than the control group after 8 intervention sessions. This study concludes that SMR NFT is effective for increasing SMR during action preparation and for enhancing golf putting performance. Moreover, greater SMR activity might be an EEG signature of improved attention processing, which induces superior putting performance

Higher power of sensorimotor rhythm is associated with better performance in skilled air-pistol shooters

Cheng M-Y, Wang K-P, Hung C-L, et al. Higher power of sensorimotor rhythm is associated with better performance in skilled air-pistol shooters. Psychology of Sport and Exercise. 2017;32:47-53.Objectives Psychomotor efficiency has been linked with processing efficiency during sport performance. Reduced cortical activity in the sensorimotor area has been related to less variability in the movement preparation that is conducive to skilled motor performance. This study proposes sensorimotor rhythm (SMR), 12–15 Hz of the electroencephalography (EEG) in the sensorimotor area, may be used to investigate psychomotor efficiency in sports performance. Method Twenty-four skilled air pistol shooters were recruited to fire 40 shots while EEG and shooting accuracy were recorded. Results The data show that improved performance of skilled shooters is associated with higher SMR power during the last second and lower coherence on high alpha power at Fz-T3 before action initiation. A negative relationship is also exhibited between the SMR power and the shooting performance during the aiming. Conclusions This finding suggests that reduced interference from sensorimotor processing, as reflected by elevated SMR power, may be related to improved processing efficiency during the aiming period. We conclude that SMR may be used to understand psychomotor efficiency underlying air-pistol shooting performance

The relationship of muscular endurance and coordination and dexterity with behavioral and neuroelectric indices of attention in preschool children

This study investigated the associations of non-aerobic fitness (NAF) and motor competence (MC) with attention in 4–6 year-old preschoolers. The allocation of attentional resources and speed of stimulus categorization were examined using the amplitude and latency of P3 of event-related potentials respectively, while cortical activation related to general attention and task-specific discriminative processes were examined using event-related desynchronization (ERD) at lower (8–10 Hz) and upper (10–12 Hz) alpha frequencies, respectively. Seventy-six preschoolers completed NAF (muscular power, muscular endurance, flexibility, balance) and MC (coordination and dexterity, ball skills, agility and balance) test batteries. Electroencephalogram was recorded while participants performed an auditory oddball task. After controlling for age and MC, muscular endurance was positively related to P3 amplitude. MC and its coordination and dexterity sub-component were positively related to task performance, with higher levels of coordination and dexterity showing an additional association with greater upper alpha ERD between 700 and 1000 ms following stimulus onset after controlling for age and NAF. These findings suggest relationships of NAF and MC with early childhood neurocognitive function. Specifically, muscular endurance is related to the neuroinhibition in facilitating effective allocation of attentional resources to stimulus evaluation while coordination and dexterity are related to cortical activation underlying strategic attentional preparation for subsequent stimulus evaluation
