  1. Geolocating Video Neil Gealy

  2. Show video

  3. Ground Truth (red)Query Frames (blue)

  4. Removed bad matches by Clustering • Chose a radius and a threshold • Checked to see how many other points were located within the radius and compared it to the threshold • Did consecutive clustering in this manner • First with a high radius and threshold to find the large cluster • Second with low radius and threshold to refine the trajectory

  5. Ground Truth

  6. Calculated Trajectory w/ Clustering

  7. Ground Truth (green)Calculated Trajectory (red)

  8. Next Steps • Complete testing on higher quality videos • Key Frame selection to get a consistent frame sampling • Currently if sampling a certain frames per second, we get large groups of points when the person or vehicle is stationary
