Claim 5:
6. A method comprising:
capturing a first visual media file of a first subject;
capturing a second visual media file of a second subject;
capturing a third visual media file of a third subject;
analyzing the visual media files with a vortex similarity engine to determine whether each of the visual media files depicts a travelling object vortex;
determining a vortex similarity ratio with the vortex similarity engine to indicate whether each of the visual media files contain a vortex made by a travelling object;
determining an overall travelling object vortex probability based on an aggregation of the vortex similarity ratios using a probability calculator; and
triggering an alert if a majority of the visual media files analyzed by the vortex similarity engine have a vortex similarity ratio above a threshold value.
