Extracting Vehicle Trajectories Using Unmanned Aerial Vehicles in Congested Traffic Conditions

Figure 7

Extracted vehicle trajectories (a) before postprocessing by detection with 94.5% F-measure and (b) after postprocessing by detection with 94.5% F-measure. (c) Tracking errors including false positives and mismatches in trajectory data. (d) Results of postprocessing to remove tracking errors. The numbers in figures indicate the start and end points of each identified vehicle.
