Abstract: A vessel rendezvous system obtains position data from each vessel of a plurality of vessels operating within a navigable area. Using the position data from each vessel, the vessel rendezvous system determines that a first vessel was engaged in an action with a second vessel within the navigable area. In response to this determination, the vessel rendezvous system provides an indication that the first vessel and the second vessel were engaged in the action within the navigable area.

Abstract: A first digital representation in an image and a second digital representation in a second image is identified based at least in part on specified criteria. A first epipolar line in the second image is determined based at least in part on a position of the first digital representation in the image. A second epipolar line is determined based at least in part on a position of the second digital representation in the second image. At least one cost value is determined based at least in part on the first digital representation, the second digital representation, the first epipolar line, and the second epipolar line. The first digital representation and the second digital representation are determined, based at least in part on the at least one cost value, to represent a same object. The first digital representation is associated in a data store with the second digital representation.
