20080204569 | Method and System for Indexing and Searching Objects of Interest across a Plurality of Video Streams - A seed search of a subset of analytical data corresponding to video objects displayable in a plurality of video frames is carried out to identify video objects that most closely match a selected video object and then complete searches of the analytical data may be carried out so as to identify video objects that most closely match each video object identified during the seed search. The video objects having the greatest number of occurrences of being identified during the complete searches may be displayed by a graphical user interface (GUI). In this way, the GUI may display the video objects in an order based on how closely each video object matches the selected video object and/or a video object identified during the seed search, which may an order different than an order based on a time when each video object was captured. | 08-28-2008 |
20080205773 | VIDEO DATA MATCHING USING CLUSTERING ON COVARIANCE APPEARANCE - Video data matching includes both a single region of data and sequences of regions of data. In an embodiment, a video processing system selects, from a first matrix row corresponding to a test appearance model, one or more other appearance models as a function of similarity measures populating the first matrix row. After selection of the one or more other appearance models, the system then selects, from other matrix rows corresponding to the one or more other appearance models selected in the first step, one or more additional appearance models as a function of the similarity measures populating the other matrix rows. The system then ranks the appearance models selected from the first matrix row and the other matrix rows. | 08-28-2008 |

20080273751 | Detection and Tracking of Moving Objects from a Moving Platform in Presence of Strong Parallax - Among other things, methods, systems and computer program products are described for detecting and tracking a moving object in a scene. One or more residual pixels are identified from video data. At least two geometric constraints are applied to the identified one or more residual pixels. A disparity of the one or more residual pixels to the applied at least two geometric constraints is calculated. Based on the detected disparity, the one or more residual pixels are classified as belonging to parallax or independent motion and the parallax classified residual pixels are filtered. Further, a moving object is tracked in the video data. Tracking the object includes representing the detected disparity in probabilistic likelihood models. Tracking the object also includes accumulating the probabilistic likelihood models within a number of frames during the parallax filtering. Further, tracking the object includes based on the accumulated probabilistic likelihood models, extracting an optimal path of the moving object. | 11-06-2008 |

20100016754 | IMPAIRED SUBJECT DETECTION SYSTEM - 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. | 01-21-2010 |
