Abstract: A system for biometric exclusion of certain individuals from entering a facility. A biometric exclusion system may use biometric acquisition and matching and a database to screen a large population of subjects by looking for individuals enrolled in a database. A screening approach may be used to match biometrics having sufficient quality of any individuals attempting to enter the facility, relative to biometrics of individuals stored in the database. A biometric, such as that of a face or an iris, of an individual may be obtained with the individual's knowledge or cooperation. The database may have biographical information pertinent to an individual having a biometric in the database. There may be an associated system which may be used to enroll individuals by entering their biometrics in the database.

Abstract: An adaptive iris matching approach for processing images of irises having a quality not sufficient for conventional non-adaptive matching approaches. Visible regions in a radial direction on an iris, without segmenting a circumferential of the iris, may be processed. A boundary of the visible region of the iris may be estimated. An iris map may be constructed with the non-visible portion of the iris masked. The iris map may be at least partially encoded. Partial codes of the iris map may be extracted to index at least portions of a database containing iris information. Irises may be retrieved from the database with an iris code as a query.

Abstract: A distributed agile illumination system and method associated with multiple coordinated illumination sources for projecting a large amount of illumination on a subject at a distance and with an eye safe level of illumination at a close range. An entire scene may be imaged via an image capturing device and a targeted subject with respect to the scene may be detected and prioritized. An initial calibration may be performed to determine a relative geometric location of the illumination sources and the image capturing device with respect to each other. The subject's predicted location and the geometric location may be employed to determine an offset position for each of the independent illumination sources. A pan/tilt device and optional mirror associated with each illumination source utilizes the offset position to point each illumination source towards the subject to acquire better imagery at varying subject distances.

Abstract: A system for detecting abnormal eye movement in a subject to indicate possible impairment of the subject. The subject may be presented with a visual pattern to observe. The visual pattern may cause the subject's eyes to move. Images of the eye movements may be captured. An eye motion pattern may be computed from the images. The eye motion pattern may be classified relative to other eye motion patterns or a guide. The classification may indicate whether there appears to be an abnormal movement of the eye and thus an impairment of the subject. An identification of the subject may be obtained according to a biometric from the images and used to retrieve the subject's baseline eye motion pattern. A comparison of the computed eye motion pattern and the baseline eye motion pattern may indicate whether there is abnormal movement of the eye and thus an impairment of the subject.

Abstract: A process to capture in-focus face images of a subject looking at a display unit. The system alters the content of the display to get the subject to move into the optimal focus position for a camera. If the subject is farther from the camera than an optimal distance, the displayed content is altered to cause the subject to move closer to the display unit. If the subject is closer to the display unit than an optimal distance, the displayed content is altered to cause the subject to move further away from the display unit. If the subject is at an optimal distance, the displayed content is maintained or corrected. An image of the subject's face is acquired, and the image is processed.

Abstract: A video-enabled rapid response system and method that integrates identification technology and tracking technology in order to rapidly alert the most appropriate person to an incident. Such an approach includes a strong identification mechanism to get a positive identification on a person and a weak identification mechanism to maintain location information for the person moving in a facility. The system can rapidly determine the closest person with skills and or authority to respond when an incident occurs at a particular location and then pass an alert to them via a paging mechanism. The system combines strong and weak identification mechanism in order to provide accurate subject identification and tracking over the large facility.

Abstract: A device for detecting the presence of human skin including an illuminator source for providing a first IR band and a second IR band. The first IR band is capable of being reflected from skin and the second IR band is capable of being absorbed by skin. A detector receives the first and second IR band after the bands have contacted the skin and provides a signal indicating the presence or absence of each of the first and second IR bands. A processing unit processes the signal and indicates the presence of skin when the first IR band is present and the second IR band is absent. The preferred first IR band is about 0.8 to about 1.4 ?m and the second IR band is about 1.4 to about 2.2 ?m. Preferably one illuminator interacts with two detectors, one for each of the two IR bands.

Abstract: A method and apparatus for automatically focusing a camera that may rely upon ambient light for auto focusing and flash illumination for image capture. A correction factor may be determined that is based at least in part on a range between the camera and a desired subject. The camera focus may be adjusted in accordance with the correction factor prior to capturing a capture image using flash illumination.

Abstract: A system using face and iris image capture for recognition of people. The system may have wide field-of-view, medium field-of-view and narrow field-of-view cameras to capture images of a scene of people, faces and irises for processing and recognition. Matching of the face and iris images with images of a database may be a basis for recognition and identification of a subject person.

Abstract: A device for detecting the presence of human skin including an illuminator source for providing an IR band capable of being absorbed by skin. A detector receives the IR band after the band has contacted the skin and provides a signal indicating the presence or absence of the IR band energy. A processing unit processes the signal and indicates whether skin has been presented when the band is substantially reflected, indicating no skin, and when it is substantially absent, indicating skin present. The preferred IR band wavelength is about 1.4 to about 2.2 ?m.

Abstract: A method, system, and computer program product is disclosed for selective filtering of video and audio content. Incoming content (e.g., video content and/or audio content) is broken into segments that are individually, on a segment-by-segment basis, analyzed using user-defined criteria, referred to as “cues”. Based on the quantity and weight of the cues in the segment, the segment is rated, i.e., given a score. If the score of a particular segment is above a predetermined threshold, the segment is stored for later use. If the segment is at or below the predetermined threshold, the segment is considered irrelevant or “uninteresting” relative to the user criteria, and the segment is discarded. Incoming content is buffered and, in parallel, a cue analysis is performed to break the content into segments and perform the rating process. In this manner, the streaming incoming content can be constantly monitored and analyzed and only the relevant/interesting segments are saved.
