摘要： A method includes processing a video stream on at least one first camera device to identify actionable motion objects (AMOs). The at least one first camera device or computer system in communication therewith is caused to transmit metadata associated with the identified AMOs to at least one second camera device. A viewing area of the at least one second camera device is dynamically controlled in response to the metadata to enable the at least one second camera device to track and focus on at least one of the identified AMOs.

摘要： A method for secure video surveillance with privacy features includes processing a video stream on a camera device to identify actionable privacy objects (APOs), extracting coordinates associated with the identified APOs to a metadata stream, and masking the identified APOs in the video stream. The video stream and the metadata stream are stored on at least one memory device associated with a remote video management system (VMS) that is communicatively coupled to the camera device. Selected ones of the identified APOs in the video stream are unmasked based on received user credentials, and using the extracted coordinates in the metadata stream, to create a modified video stream. The modified video stream is presented on a remote display device that is communicatively coupled to the remote VMS. A system for secure video surveillance is also provided.

摘要： According to at least one example embodiment, a method and corresponding apparatus of pruning video data comprise detecting motion areas within video frames of the video data based on short-term and long-term variations associated with content of the video data. Motion events, associated with the content of the video data, are then identified based on the motion areas detected, corresponding filtered motion areas, and variation patterns associated with the video data. Based on the motion events identified, a storage pattern for storing video frames of the video data is determined. The video frames are stored according to the determined storage pattern.

摘要： People detection can provide valuable metrics that can be used by businesses, such as retail stores. Such information can be used to influence any number of business decisions such a employment hiring and product orders. The business value of this data hinges upon its accuracy. Thus, a method according to the principles of the current invention outputs metrics regarding people in a video frame within a stream of video frames through use of an object classifier configured to detect people. The method further comprises automatically updating the object classifier using data in at least a subset of the video frames in the stream of video frames.

摘要： An embodiment of the present invention includes a master camera that may record master metadata regarding an object of interest and communicate the master metadata to a slave camera. The slave camera may zoom, pan, or tilt to isolate and record more detailed image data regarding the object of interest based on the master metadata. In addition, the slave camera may record slave metadata regarding the object of interest. The master and slave metadata may be stored associated with the recorded image data enabling a later search for the object of interest to be expedited. The recorded image data including the object of interest may be identified with greater ease as it may be guided by the master or slave metadata, or a combination thereof. According to embodiments presented herein, processing time for searching and identifying an object of interest may be reduced by enabling a search on the metadata associated with image data, rather than by searching the image data itself.
