A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
In response to the shortcomings of human guards to watch surveillance monitors long-term, the first solution was to add motion detectors to cameras. It was reasoned that an intruder's or perpetrator's motion would send an alert to the remote monitoring officer obviating the need for constant human vigilance.
Video tracking is the process of locating a moving object (or multiple objects) over time using a camera. It has a variety of uses, some of which are: human-computer interaction, security and surveillance, video communication and compression, augmented reality, traffic control, medical imaging [1] and video editing.
Motion detection can now be distributed, so that the cameras do motion detection themselves and only send video when motion is detected. Alternately, motion detection can still also occur in the VMS. Some VMS do not have motion detection and rely exclusively on it being done in the camera.
Moving object detection is to recognize the physical movement of an object in a given place or region. [2] By acting segmentation among moving objects and stationary area or region, [3] the moving objects' motion can be tracked and thus analyzed later. To achieve this, consider a video is a structure built upon single frames, moving object ...
Egomotion estimation is used to determine the location of a camera by analyzing its output signal. Motion detection: Motion detection is used to determine the presence of relevant motion in the observed scene. Shape recognition: Shape recognition is used to recognize shapes in the input video, for example circles or squares.
