Abstract: A method of progressive analysis for assessment of occluded data is disclosed. In a particular embodiment, the method includes capturing sensor data from at least one sensor, identifying a target of interest using the sensor data, and determining a location and orientation of the target of interest using a last computed direction of travel of the target. The method also includes segmenting the sensor data of the target of interest into segments for analysis and determining whether a particular segment of the segments is occluded. In addition, the method includes determining whether additional sensor data from the at least one sensor confirms that the particular occluded segment is no longer occluded allowing unresolved analysis to be supplemented with progressive analysis to provide incremental resolution to the analysis.

In a particular embodiment, the method includes scanning an electronically stored document, identifying at least one visually orientated object within the document, analyzing the at least one visually orientated object to generate a textual description of the at least one visually orientated object, and embedding the textual description within the electronically stored document, and storing a converted document with the embedded textual description for distribution to users of text to speech synthesizers and Braille output devices. In addition, the method includes identifying text characters within the at least one visually orientated object. The text characters within the at least one visually orientated object are used in generating the textual description of the visually orientated object.

Abstract: A passive outdoor millimeter wave illuminator for use with a concealed object detection system is disclosed. In a particular embodiment, the illuminator includes a panel having a plurality of horizontal louvers each having reflective properties for reflecting millimeter wave energy from the sky to a target and a pair of rear support arms for biasing the panel upwards. The illuminator further includes a base wherein a lower portion of the panel is rotatably mounted to a front edge of the base and the rear edge of the base is fixed to a lower end of the rear support so that the panel is capable of rotatable motion in a horizontal plane relative to the base. In addition, a slidable bushing engaged with a portion of the rear support arms is frictionally operable as to maintain the panel at the desired angle.

The system provides inherent background/peripheral motion and optical clutter mitigation by virtue of its booth-like design. The system can additionally include x-ray baggage machines, iris scanners, biometrics, finger readers, palm readers, metal detectors, backscatter x-ray, nuclear quadrupole resonance, explosives-trace detectors (“sniffers”), and access control cards.

Abstract: A system and method for manipulating real-time video playback time-synchronized with millimeter wave imagery is disclosed. In a particular embodiment, millimeter wave imagery and visible spectrum video images are combined to form composite images in real-time to detect concealed objects on a person. A graphical user interface (GUI) manipulates the displayed millimeter wave imagery, video images and composite images and controls displaying user selected portions of the synchronized recorded images. The composite images are automatically encoded with event data when a concealed object is detected and an alert is generated, or that information is accessed from a datafile or database structure. The GUI controls the playback and viewing of those composite images having encoded event data.

Abstract: A system and method for autonomous concealed object detection and threat assessment. Image data is received from a millimeter wave imaging device comprising at least one scan of a scene. The image data is enhanced thereby creating enhanced image data comprising a plurality of enhanced image pixels. The enhanced image data is evaluated thereby identifying at least one subject within the enhanced image data. The subject is separated from a background within the enhanced image data. The contrast of the subject is enhanced within the enhanced image data. Concealed physical objects associated with the subject within the enhanced contrast image data are detected, thereby detecting at least one concealed object associated with the subject. A representation of the subject and the concealed physical object is displayed on a display device.

Abstract: A millimeter wave object detection system includes a millimeter wave imager and a data entry device configured to assign assessment information to events where a concealed object is detected by an operator/observer or automated computer program interrogating imagery produced by the millimeter wave imager. A computer is programmed to store assessment data from the data entry device into a database, and statistical operations can be performed upon the database.

Abstract: A system for the rapid deployment of a concealed object detection system (CODS) is disclosed. In a particular embodiment, a base having side walls about its periphery extending upwards are adapted to secure CODS camera and equipment within the base.
