摘要:
A method is provided for efficiently managing the data bandwidth and storage requirement of a video camera by using an object detection engine to process a video captured by an image sensor even prior to compression. The method manages the video transmission bandwidth by processing the captured video based on information extracted by the object detection engine on a frame by frame basis without the loss of critical information. A related computer vision system is also provided..
摘要:
A method for monitoring and securing a facility without employing a manned control center, according to which a server acquires surveillance data from each of a plurality of distributed surveillance devices deployed within or adjacent to a given security sensitive facility. Then the server receives an intrusion alert from a guard, or from one or more of the plurality of surveillance devices to initiate a triggering event, if the acquired surveillance data is indicative of activity that has been detected at an indicated location. A first guard is alerted to assess the severity of the detected activity and the triggering event is terminated if found by the first guard to be of a low severity, or an interception operation initiated by self-dispatching or dispatching one or more additional guards to a close by location that holds tactical advantage relative to the indicated location if the triggering event was found by the first guard to be of a high severity.
摘要:
A system and method for operating a network security system implementing security cameras, motion sensors, access control systems, security door locks, and mobile panic button devices within a monitored area. Security cameras transmit video to a network video recorder and the video is analyzed by a video analytics system to determine if a security event is occurring. If a security event occurs, a security control system calls a dispatch service, which transmits a notification to only those security guards who are within a given area of the event. Video image data is provided at mobile user devices based on position information of said mobile user devices relative to locations of alarm condition.
摘要:
In accordance with one aspect of the present technique, a method includes receiving one or more videos from one or more image capture devices. The method further includes generating a video-loop of the person from the one or more videos. The video-loop depicts the person in the commercial site. The method also includes generating an action clip from the video-loop. The action clip includes a suspicious action performed by the person in the commercial site. The method further includes generating an activity summary of the person including the video-loop and the action clip.
摘要:
In an imaging intrusion detection method, a converging lens coupled to a plurality of light sources forms a plurality of parallel light beams to illuminate a secure area with a plurality of dots, an intrusion detection camera captures a dotted image illuminated with dots, the captured dotted image is stored as reference dotted information in a memory unit, the intrusion detection camera regularly captures the secure area that is illuminated with dots, and when an input image is generated, dotted information is extracted from the input image and compared with the reference dotted information, after which it is determined, on the basis of a certain change in the dots, if an intrusion has occurred.
摘要:
A technique for video processing includes: receiving video from a scene; detecting moving pixels in the video; detecting line segments or motion blocks in the video based on the detected moving pixels; identifying targets in the video based on the detected line segments or motion blocks; tracking targets in the video based on the identi fied targets; and managing the tracked targets in the video.
摘要:
A method and apparatus for performing video surveillance of a field of view is disclosed. In one embodiment, a method for performing surveillance of the field of view includes monitoring the field of view and detecting a moving object in the field of view, where the motion is detected based on a spatio-temporal signature(e.g., a set of descriptive feature vectors) of the moving object.
摘要:
A video based system and method (fig. 1) for detecting and counting persons (11 of fig. 1) traversing at least two areas being monitored (11 and 13 of fig. 1). The method includes the steps of initialization of at least one end unit, having at least a camera (12 of fig. 1), the camera producing images of at least a first area being monitored and a second area being monitored, digitizing the images and storing the digitized images in a non-volatile memory unit (22 of fig. 1) and a working memory unit (24 of fig. 1), detecting potential persons in the images; comparing the digitized images of objects detected in the first area and second area being monitored with digitized images stored in the working memory unit.
