    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: A LPC/ISA bridge and its bridging method are disclosed for bridging an LPC interface to an ISA interface. The LPC/ISA bridge is activated in response to a duty cycle indicative signal (LFRAME#), and serially transforms related command, address and data information from command/address/data lines (LAD[3:0]) of the LPC interface into address, data and control signals of the ISA interface. Therefore, the problem as to the interface incompatibility is solved.

    摘要: Systems and methods are disclosed for analyzing, managing and cataloguing video tracks generated by a video surveillance system. Systems and methods operating in accordance with the present invention receive video tracks from a video surveillance system; analyze them for particular categories of, for example, objects or events, assign unique identifying tags to the video tracks; and save them in highly-cross-referenced databases so that video tracks containing, for example, particular objects or events can be easily searched for and recalled. In addition, the present invention provides browsing facilities for viewing events that have just elapsed, events that are occurring in near real-time.

    摘要: A method of retrieving storage capacity of damaged sector. A storage medium comprising a storage capacity part and a reserved capacity part is provided. The storage capacity part comprises multiple primary sectors, while the reserved capacity part comprises multiple secondary sectors. The storage medium is scanned to find and record a damaged sector in the storage capacity part. An identity field of the damaged sector is overwritten by an null identity field of one of the secondary sectors. The identity field of the damaged sector is written into the secondary sector.
