Abstract: A system and method is provided for monitoring the activities and/or locations of wireless units in a wireless network independent of location-based service preferences of those wireless units. That is, a system and method is provided that allows an authorized requester override location-based service preferences (e.g., privacy settings) that may be set for a wireless unit. In this regard, an authorized entity may be able to effectively locate and/or monitor the activities of a wireless unit associated with an individual of interest. Furthermore, if proper authorization exists, such monitoring may be done surreptitiously without the wireless unit user's knowledge and/or consent. For example, in some instances, law enforcement agencies may be authorized to monitor call traffic and/or the location of persons utilizing wireless units.

Abstract: A cooperative camera network involving segmenting an image of an object and extracting a color signature from it. The color signature may be matched with the other signatures in an attempt to identify the object. There also can be combining and fusing the tracking of people and objects with image processing and the identification of the people and objects being tracked in an area or facility.

Abstract: Thermal infrared image data of at least a region of a face of a person in an enclosure is provided. The enclosure, for example, may include a first enclosed volume and a second enclosed volume physically separated from the first enclosed volume. The first enclosed volume may include an entrance door sized to allow a person to enter the first enclosed volume. The enclosure provides a controlled environment for performing measurements (e.g., capturing thermal infrared image data) for use in determining a physiological state of a person (e.g., anxiety, deception, etc.).

Abstract: Thermal image data of at least a region of a face of a person is provided. The thermal image data is transformed to blood flow rate data which includes a slope representative of the change of blood flow rate over time. The slope is compared to a slope threshold to determine a physiological state of the person. For example, it may be determined whether the person is deceptive or non-deceptive, e.g., deceptive with respect to an elicited response from the person.

Abstract: Detection of a person disguised with one or more artificial materials includes detecting reflection from at least one portion of a head of a human body in at least a portion of an upper band of the near infrared spectrum. The presence of an artificial material associated with the head of the human body is determined based on the detected reflection.

Abstract: A method and system for use in detecting a face of a person includes providing image data representative of reflected light of a scene in at least one bandwidth within a reflected infrared radiation range. Regions of the scene in the image data which may correspond to one or both eyebrows of a person and which may correspond to one or both eyes of the person are extracted from the data. The extracted regions which may correspond to one or both eyebrows of the person are combined with the extracted regions that may correspond to one or both eyes of the person resulting in a composite feature image. The composite feature image is searched based on model data representative of an eye region to detect one or both eyes of the person.

Abstract: Thermal image data of at least a region of a face of a person is provided. The thermal image data is used to determine a physiological state of a person, e.g., anxiety. For example, anxiety may be determined by a comparison of the thermal image data to a baseline, or by comparison of thermal image data for one region of the person's face to another.

For example, anxiety may be determined by a comparison of the thermal image data to a baseline, or by comparison of thermal image data for one region of the person's face to another.

Abstract: Thermal image data of at least a region of a face of a person is provided. The thermal image data is transformed to blood flow rate data and may be used to determine whether the person is deceptive or non-deceptive based on the blood flow rate data, e.g., deceptive with respect to an elicited response from the person.

Abstract: A detection method and system that detects reflection from a scene in at least a portion of an upper band of the near infrared spectrum (e.g., at least a portion within the range of 1.4 &mgr;m and above in the near infrared spectrum). The presence of a human body in the scene is then determined by comparing the reflection of at least one region of the scene (e.g., at least one region of the scene including a face region of the human body) to at least one other region of the scene (e.g., at least another region of the scene including one or more inanimate objects).

Abstract: A method and system for use in monitoring a search area includes the provision of a plurality of time varying distributions for each pixel of image data representative of a search area. The plurality of time varying distributions for each pixel are ordered based on a probability of the time varying distribution being representative of background or foreground information in the search area. For each pixel, an attempt to match update pixel value data to each of all of the plurality of time varying distributions provided for the corresponding pixel is performed to determine if the update pixel value data is representative of background or foreground information in the search area.

Abstract: A method and system for use in monitoring a search area includes the provision of object path data representative of at least one object path of one or more moving objects in the search area. Defined normal and/or abnormal object path feature models are provided based on one or more characteristics associated with normal or abnormal object paths of moving objects in the search area. The feature models may be based on a clustering process. The object path data is compared to the one or more defined normal and/or abnormal object path feature models for use in determining whether the object path is normal or abnormal.

Abstract: A system and method for use in monitoring a search area includes positioning a plurality of imaging devices at one or more installation sites such that corresponding fields of view for the plurality of imaging devices cover a defined search area. For example, each field of view of each imaging device may include a field of view portion which overlaps with at least one other field of view of another imaging device, e.g., the field of view portion which overlaps may be greater than about 25 percent and less than about 85 percent of the field of view of the imaging device. Further, for example, images may be fused using one or more homography transformation matrices.
