摘要： A method and system for real time processing of a sequence of video frames. A current frame in the sequence and at least one frame in the sequence occurring prior to the current frame is analyzed. Each frame includes a two-dimensional array of pixels. The sequence of video frames is received in synchronization with a recording of the video frames in real time. The analyzing includes performing a background subtraction on the at least one frame, which determines a background image and a static region mask associated with a static region consisting of a contiguous distribution of pixels in the current frame. The static region mask identifies each pixel in the static region upon the static region mask being superimposed on the current frame. The background image includes the array of pixels and a background model of the at least one frame and does not include any moving object.

摘要： A method for processing a time-ordered sequence of video frames. The method is implemented by execution of program code on a processor of a computer system. Each frame includes a two-dimensional array of pixels and a frame-dependent color intensity at each pixel. A current frame and at least one frame occurring prior to the current frame in the sequence are analyzed via a background subtraction on the at least one frame to determine a background image and a static region mask associated with a static region. The background subtraction determines an existence of a static object relating to the static region. A status of the static object is determined, the status being either that the static object is an abandoned object or that the static object is a removed object. The determined status is stored in a data storage medium of the computer system.

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： 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.
摘要翻译：该系统和方法遮盖关于一个或多个图像的描述性图像信息。该系统包括用于从一个或多个图像中选择描述图像信息的选择器，将描述信息变换为变换状态的变换器，以及向图像提供授权标准的授权器。在优选实施例中，变换状态是用描述信息编码的各个图像。描述性信息可能被遮蔽，使得仅当一个或多个授权输入满足授权标准时才能对解码状态中的描述信息进行解码。
