摘要： An occlusion detection system and method include a decomposer configured to decompose an image into a set of hierarchical parts. A hierarchy of classifiers is employed to detect features in the image and the hierarchical parts. A logical operation is configured to logically combine a classification result from at least two of the classifiers to detect an occlusion state of the image.

摘要： In general, the present invention allows any number of sequential filter graphs to be created based on a pub-sub architecture/model. Specifically, under the present invention, the filters (components) will publish their ideal priorities of accessing data source, an ideal input data type, and a unique alternative input data type. A mechanism such as a queue manager will receive the publication(s) and determine an appropriate order/sequence of the filters based on their ideal priorities. The queue manager will also assign an output data type to each filter (an optionally an alternative output data type) based on the ideal input types specified in the publish messages. The queue manager will then transmit messages (e.g., a subscribe message) to the filters with the determined order and assigned data types.

摘要： Techniques for tracking entities using a single overhead camera are provided. A foreground region is detected in a video frame of the single overhead camera corresponding to one or more entities. It is determined if the foreground region is associated with an existing tracker. It is determined whether the detected foreground region is the result of at least one of a merger of two or more smaller foreground regions having corresponding existing trackers and a split of a larger foreground region having a corresponding existing tracker when the detected foreground region is not associated with an existing tracker. The detected foreground region is tracked via at least one existing tracker when the foreground region is associated with an existing tracker or the foreground region is the result of at least one of a merger and a split.

摘要： A system and method to estimate the absolute coarse pose of a rigid body, and more specifically of an individual's head as captured by overhead wide-angle cameras, by integrating position and pose information. Position information ideally includes three-dimensional position information provided by range finders or derived from images captured by multiple cameras. The three-dimensional position information can additionally be employed to determine the anchored viewing ray for the object.

摘要： The system and method obscures descriptive image information about one or more images. The system comprises a selector for selecting the descriptive image information from one or more of the images, a transformer that transforms the descriptive information into a transformed state, and an authorizer that provides authorization criteria with the image. In a preferred embodiment, the transformed state is the respective image encoded with the descriptive information. The descriptive information can be obscured so that the descriptive information in the transformed state can be decoded only if one or more authorization inputs satisfy the authorization criteria.

摘要： A system for automatically acquiring high-resolution images by steering a pan-tilt-zoom camera at targets detected in a fixed camera view is provided. The system uses automatic or manual calibration between multiple cameras. Using automatic calibration, the homography between the cameras in a home position is estimated together with the effects of pan and tilt controls and the expected height of a person in the image. These calibrations are chained together to steer a slave camera. The manual calibration scheme steers a camera to the desired region of interest and calculates the pan, tile and zoom parameters accordingly.

摘要： A novel system and method of treating the output of moving cameras, in particular ones that enable the application of conventional “static camera” algorithms, e.g., to enable the continuous vigilance of computer surveillance technology to be applied to moving cameras that cover a wide area. According to the invention, a single camera is deployed to cover an area that might require many static cameras and a corresponding number of processing units. A novel system for processing the main video sufficiently enables long-term change detection, particularly the observation that a static object has been moved or has appeared, for instance detecting the parking and departure of vehicles in a parking lot, the arrival of trains in stations, delivery of goods, arrival and dispersal of people, or any other application.

摘要： The present invention provides an item scanning system in which an appearance of an item is received (e.g., at checkout). The appearance is captured with an image capture device (e.g., still frame camera, video camera, etc.) that can be collocated with a barcode scanner. In being collocated, the image capture device can be positioned proximate (e.g., near, attached to, etc.) the bar code scanner, integrated within a common housing/unit with the barcode scanner, etc. In any event, a search engine will then search a database of items based on the appearance to identify a set of items that potentially match the item. When one of the set of items is selected (e.g., by the checkout clerk), the selection will be received and stored for future investigation/auditing.
