Classification of targets in a digital image is accomplished by evaluating windowed portions of the image. A weighted sum is formed for each overlapping windowed portion of an image using a feature set corresponding thereto, each window's feature set and weighted sum is normalized, and a context...

A controlled corrosion release system for a payload is provided. The payload is submerged in a conductive medium, such as seawater. The system includes clips which restrain the payload against a housing. A circuit is established to allow electrical current to flow from a power source contained...

A crowd state characterization system utilizes a plurality of processors to analyze video streams from numerous videos to select videos and/or video frames of interest. The processors digitize dismounts such as pedestrians and the like and then analyze the digitized pedestrians. The frames of video...

A method is provided for enhancing two-dimensional contrast and range images rendered from three-dimensional STIL data. A series of sequential steps are provided for each of the rendered contrast image data and rendered range image data. Briefly, the rendered contrast image data is scaled based on...

A method is provided for enhancing two-dimensional contrast images rendered from three-dimensional STIL data. Briefly, the rendered contrast image data is scaled based on a mean intensity value of all pixels of data therein, stretched to a predetermined dynamic range, modified to compensate for...

A method is provided for enhancing two-dimensional range images rendered from three-dimensional STIL data. Briefly, the rendered range image data is modified to compensate for jitter effects associated with the STIL camera system, has background portions of the resulting data modified to compensate...

A field data collection and relay station is equipped to receive sensor data from locations in a region. The station has directional antennas that are focused to transmit and receive energy in and from unique directions. The station establishes a wireless network in which the sensor data is...

A barrier for small boats has a plurality of flotation modules on lines extending across a waterway. The flotation modules are cast from a buoyant concrete mixture of cement, water, beaded forms of expanded polystyrene, and polypropylene fibers that is non-water-absorbing, crushable, not...

A platform, breakwater, or endless track includes an array of molded cells interconnected by a system of elongate flexible members, such as wire ropes or lines. The molded cells are cast in molds located at overlapping portions of the cables. The molds may be flexible nylon bags having openings for...

A folding deployment system for solar panels provides a portable solar collecting power station that can be easily packaged and deployed for use in diverse environments. A solar array frame extends and contracts in accordion fashion. Solar panels mounted on the solar array frame are pivotally...
