    摘要: A computer-based system for performing scene content analysis for human detection and tracking may include a video input to receive a video signal; a content analysis module, coupled to the video input, to receive the video signal from the video input, and analyze scene content from the video signal and determine an event from one or more objects visible in the video signal; a data storage module to store the video signal, data related to the event, or data related to configuration and operation of the system; and a user interface module, coupled to the content analysis module, to allow a user to configure the content analysis module to provide an alert for the event, wherein, upon recognition of the event, the content analysis module produces the alert.

    摘要: Input video data is processed to detect a change in a posture of a person shown in the video data. The change of posture may be the result of an event, for example, the person falling or getting up. The input video data may include a plurality of frames. Objects in the frames are tracked and then classified, for example, as human and non-human targets. At least one of the position or location of a human target in the frames is identified. Changes in the location or position of the human target between the frames is determined. When the change in at least of the position or location exceeds a predetermined threshold, a falling down event or a getting up event is detected. The changes in the position or location of the human target can be determined based on a number of different factors.
