  • Patent number: 9652674
    Abstract: An ice analyzer includes processing circuitry configured to receive a radiometer image including a geographic area including ice, receive a radar image including at least a portion of the geographic area, perform ice/water discrimination of the radiometer image and the radar image, generate a passive ice/water mask and an active ice/water mask based on the ice/water discrimination, merge the passive ice/water mask and the active ice/water mask into a typing mask, and type the ice based on the typing mask.
    Type: Grant
    Filed: October 29, 2015
    Date of Patent: May 16, 2017
    Assignee: The Johns Hopkins University
    Inventors: Mary R. Keller, Christopher M. Gifford, William C. Walton, Nathaniel S. Winstead
  • Patent number: 9652813
    Abstract: In a risk analysis system, a risk analysis engine and a related method, incident information or activity information, which may be of a spatiotemporal nature, is analyzed. Behavioral patterns are identified in or derived from the incident information or the activity information. Observations are produced from matches of the behavioral patterns to behavior specifications. Based upon the observations, and asset vulnerability data, per-asset risks are derived.

  • Patent number: 8908919
    Abstract: A detection system includes processing circuitry configured to receive overhead image data divided into a plurality of image chips and receive metadata associated with the image data. The metadata includes ground sample distance information associated with the image data and provides an indication of ground area represented by each pixel within the image chips. The processing circuitry is further configured to screen the image chips for candidate detections based on a multi-stage screening process and determine whether to classify candidate detections as target detections. The process includes an intensity based screening stage, an object extraction stage that employs binary shape features to extract objects from detect positions identified based on an output of the intensity based screening stage, and a candidate detection identification stage employing template based and structural feature criteria to identify candidate detections from an output of the object extraction stage.
