Claim 16:
17. A system comprising:
a visual media timing device configured to capture:
a first visual media file of a first subject;
a second visual media file of a second subject;
a third visual media file of a third subject;
wherein the first, second, and third visual media files are captured at different times;

a vortex similarity engine configured to:
analyze the visual media files with a visual media classifier to determine whether each of the visual media files depicts a travelling object vortex;
determine a vortex similarity ratio to indicate whether each of the visual media files contain a vortex made by a travelling object;

a probability calculator configured to determine an overall travelling object vortex probability based on an aggregation of the vortex similarity ratios; the overall travelling object vortex probability being a measurement of a probability that the first, second, and third visual media depict a travelling object vortex; and
an alert trigger configured to trigger an alert if the overall travelling object vortex probability exceeds a predetermined threshold.
