Cortical fMRI activation produced by attentive tracking of moving targets.
Attention can be used to keep track of moving items, particularly when there are multiple targets of interest that cannot all be followed with eye movements. Functional magnetic resonance imaging (fMRI) was used to investigate cortical regions involved in attentive tracking. Cortical flattening techniques facilitated within-subject comparisons of activation produced by attentive tracking, visua...
متن کاملBrain activation during spatial updating and attentive tracking of moving targets.
Keeping aware of the locations of objects while one is moving requires the updating of spatial representations. As long as the objects are visible, attentional tracking is sufficient, but knowing where objects out of view went in relation to one's own body involves an updating of spatial working memory. Here, multiple object tracking was employed to study spatial updating and its neural correla...
متن کاملAttentive tracking of moving objects in real 3D space
Results of earlier multiple object tracking (MOT) studies imply that humans can track several moving targets in a 2D environment simultaneously. Recently, a study suggested that stereoscopic depth has positive effect on tracking multiple objects when the objects are presented separately on multiple planes. However, it remains unclear whether or not humans can track moving targets in a real 3D e...
متن کاملTracking of Moving Targets in Video Sequences
A research has been carried out finalised to the definition of a methodology useful to address the task of detection and tracking of moving targets. Algorithms performing this task for real time monitoring and surveillance purposes have been developed. Due to deformations occurring in the appearance of the target in real time video sequences, a Hierarchical Neural Network (HNN) has been used fo...
متن کاملMulti Hypothesis Tracking of Ground Moving Targets
We present an application of a multi hypothesis tracking (MHT) algorithm to the case of ground moving targets detected by GMTI (Ground Moving Target Indicator) radar sensors. The algorithms for track extraction, prediction, filtering, and track maintenance are briefly described, and exemplary tracking results for simulated MTI data are demonstrated.
