  2. Motion detector - Wikipedia

    en.wikipedia.org/wiki/Motion_detector

    A motion detector is an electrical device that utilizes a sensor to detect nearby motion. 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.

  3. Motion detection - Wikipedia

    en.wikipedia.org/wiki/Motion_detection

    Motion-detection devices such as PIR motion detectors have a sensor that detects a disturbance in the infrared spectrum. A signal can then activate an alarm, and/or a camera to capture an image or video of the event. This method's chief applications are: Detection of unauthorized entry; Turning lights on/off when an area is entered/vacated

    en.wikipedia.org/wiki/Video_content_analysis

    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.

  6. Kinect - Wikipedia

    en.wikipedia.org/wiki/Kinect

    Kinect is a discontinued line of motion sensing input devices produced by Microsoft and first released in 2010. The devices generally contain RGB cameras, and infrared projectors and detectors that map depth through either structured light or time of flight calculations, which can in turn be used to perform real-time gesture recognition and ...

  7. Motion estimation - Wikipedia

    en.wikipedia.org/wiki/Motion_estimation

    In computer vision and image processing, motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another; usually from adjacent frames in a video sequence.
