Abstract: A split-index can be employed for access to external data. The index can be created on a primary data storage system for data stored externally on a secondary data storage system. After creation, the index can be utilized to expedite at least query execution over the externally stored data. The index can be updated upon detection of changes to data. Further, even when the index is not completely up to date, the index can be exploited for query execution. Furthermore, hybrid execution is enabled with the index and without the index.

Abstract: System and method for detecting a fraudulent activity at a barcode scanner is disclosed. The method issues an alert when the fraudulent activity is confirmed by comparing the visual signature of the item being transacted over the checkout terminal to the model visual signature. The model visual signature is obtained by averaging the collection of visual signature of the item gathered over a period of time. A human validation via a remote processor is employed to confirm the fraudulent activity verified by a computer.

Abstract: An optical relay system that is capable of re-imaging an image or a pupil from a shared location to two or more optical systems, or from two or more optical systems to a shared location is disclosed.

Abstract: A method, system, and computer-readable medium for synchronizing video are described. The system captures video data with a camera, the video data including a first video data segment and a second video data segment. When a network between the camera and a hub is insufficient to allow downstream real-time streaming of the video data, the system stores the first video data segment on a first storage. When the network is sufficient to allow downstream real-time streaming of the video data, the system transfers the second video data segment from the camera to the hub, reads the first video data segment from the first storage, and transfers the first video data segment to the hub. The system stores the video data segments onto a second storage such that a non-real-time playback from the second storage shows the first video data segment and the second video data segment in sequence.

Abstract: A video tagging method, a video analytics method, and a Computer Assisted Dispatch (CAD) system use incident reports for video tagging and searching. A CAD system is integrated with field-based video surveillance systems to aid in searching video content and subsequent tagging of the video content. The systems and methods can include extracting keywords from a CAD incident report and creating a small, focused, and incident-specific dictionary on which to perform video searching in real-time. The small, focused, and incident-specific dictionary increases tagging accuracy and reduces tagging processing time in the context of video analytics. Further, a multi-pass approach in real-time continually updates and disseminates to video cameras of interest the small, focused, and incident-specific dictionary as the CAD incident report is updated and as the incident of interest plays out.

Abstract: Embodiments include methods, devices, software, and systems for identifying a person based on relatively permanent pigmented or vascular skin mark (RPPVSM) patterns in images. Locations of RPPVSMs in different images of people are point matched, and a correspondence probability that the point matched RPPVSMs are from different people is calculated. Other embodiments are also described. Other embodiments are also described and claimed.

Abstract: An image noise reduction method is provided. An image is received. A first-stage process is performed to the image to obtain a luminance information Y and a color information Cb and/or Cr corresponding to a pixel array in an YCbCr domain. A second-stage process is performed to the luminance information Y to reduce at least a luminance noise. A third-stage process is performed to the color information Cb and/or Cr to reduce at least a color noise. The luminance information Y and the color information Cb and/or Cr are then combined.

Abstract: A method for adjusting a skin color of a digital image adjusts the skin color of an input image. The method includes performing a skin color detection process on the input image to generate a skin-color probability plot Sp in a size corresponding to the input image; providing a hue-saturation lookup table named LUT_Color; performing a skin-color reproduction process on the input image to look up the LUT_Color for a chrominance pixel value for each pixel value of the input image to generate a first image, and adjust each pixel value of the first image by using the skin-color probability plot Sp to generate a second image; performing a skin color smoothing process on the second image to generate a third image; and mixing pixel values of the input image and the third image to generate a target image.

Abstract: A sensed image of the physical space is acquired by an image sensing apparatus. One or more indices are detected from the sensed image. The reliability of each of the detected results is determined by calculating a first reliability value based on the sensed image and a second reliability value based on orientation information of the image sensing apparatus. Each of the detected indices is then identified based on its first and second reliability values.

Abstract: Indices are detected from a pattern image including a plurality of indices, and first positions of the detected indices on the captured image are calculated. Using parameters associated with an image capturing apparatus, second positions indicating the positions of the indices on the captured image are calculated. While a parameter of a radial distortion of a lens of the image capturing apparatus is fixed, the parameters other than the parameter of the radial distortion of the lens of the image capturing apparatus are corrected using the differences between the first positions and the second positions. Using the corrected parameters, third positions indicating the positions of the indices on the captured image are calculated. Using the differences between the first positions and the third positions, the parameter of the radial distortion is corrected.

Abstract: The orientation of each index is estimated from a sensed image, and the index detected from the image is identified based on the orientation of an image sensing device and that of the index estimated from known coordinate information of the index. In this way, indices which are located at nearby positions but have different orientations are never misidentified, and can be stably identified. Indices can be stably identified from the sensed image in which indices located in the physical space appear.

Abstract: An index arranged on a real space is detected from an image sensed by a camera, and the position of the index in the image is calculated (S405). The index is projected onto the image sensing plane of the camera on the basis of the position and orientation information of the camera, the position information of the index, and the like (S403). A corresponding index is identified based on the distance between the detected and projected indices on the image plane, and geometric information of the index (e.g., directionality) (S408). With this method, an index can be accurately identified by a simple method.

Abstract: Picture display device comprising a cathode ray tube whose display screen (10) is provided with index electrodes (20, 21) comprising elongated conducting elements disposed substantially parallel to an axis of symmetry (50) of the display screen (10). In operation, the magnetic field of the deflection system of the cathode ray tube induces unwanted crosstalk on said index electrodes (20, 21). By cross-connecting one end (30a) of a conducting element (31) of an index electrode (20) to the opposite side end (40a) of another conducting element (41) of said index electrode (20), said crosstalk on said index electrode (20) is reduced.

Abstract: A picture display device comprising a cathode ray tube of the index type has two patterns of index elements which are electrically separated and each generate separate signals. A first pattern, which is preferably positioned at the blind edge of the display screen, can detect large-scale and, hence, low-frequency disturbances. A second pattern, which preferably extends in the visible part of the display screen, can detect high-frequency disturbances.
