  • Publication number: 20180286123
    Abstract: A system is provided that includes a 3-dimensional object, a tagging element, a tracking system and an imaging system. The tagging element is disposed at a tagging element position of the 3-dimensional object so as to correspond with an object position of the 3-dimensional object. The tracking system detects the tagging element position and orientation and outputs a tagging element detected signal based on the detected tagging element position and orientation. The imaging system generates an object image based on the tagging element detected signal. The object image corresponds to the 3-dimensional object at a generated object position and orientation corresponding to the object position and orientation.

  • Patent number: 8958602
    Abstract: A method and system are provided for processing maritime video data to improve processing time and reduce the risk of false detection. Video data input may be received from satellites, aircrafts, UAVs and other aerial vehicles. The method and system create annotated video output files indicating the location of tracked anomalies. The method and system perform an anomaly detection function on each data frame within the video input, identify anomalous regions within each data frame, and identify clusters. The method and system then perform an algorithm to discard clusters which do not meet threshold criteria to reduce the risk of false detection, as well as employ a horizon detection algorithm to eliminate superfluous image data unrelated to tracking maritime targets.
