Patent Images

1. A detection system comprising processing circuitry configured to:

  • receive overhead image data divided into a plurality of image chips;

    receive metadata associated with the image data, the metadata including ground sample distance information associated with the image data and providing an indication of ground area represented by each pixel within the image chips;

    screen the image chips for candidate detections based on a multi-stage screening process, the multi-stage process including;

    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, anda candidate detection identification stage employing template based and structural feature criteria to identify candidate detections from an output of the object extraction stage; and

    determine whether to classify candidate detections as target detections.
