Stable Visual Summaries for Trajectory Collections
2021 IEEE 14th Pacific Visualization Symposium (PacificVis)(2021)
摘要
The availability of devices that track moving objects has led to an explosive growth in trajectory data. When exploring the resulting large trajectory collections, visual summaries are a useful tool to identify time intervals of interest. A typical approach is to represent the spatial positions of the tracked objects at each time step via a one-dimensional ordering; visualizations of such ordering...
