  2. Visual sensor network - Wikipedia

    en.wikipedia.org/wiki/Visual_sensor_network

    Visual sensor networks are most useful in applications involving area surveillance, tracking, and environmental monitoring.Of particular use in surveillance applications is the ability to perform a dense 3D reconstruction of a scene and storing data over a period of time, so that operators can view events as they unfold over any period of time (including the current moment) from any arbitrary ...

  3. Virtual sensor network - Wikipedia

    en.wikipedia.org/wiki/Virtual_sensor_network

    A virtual sensor network (VSN) in computing and telecommunications is an emerging form of collaborative wireless sensor networks. [1] In contrast to early wireless sensor networks that were dedicated to a specific application (e.g., target tracking), VSNs enable multi-purpose, collaborative, and resource efficient WSNs.

  4. Wireless sensor network - Wikipedia

    en.wikipedia.org/wiki/Wireless_sensor_network

    Operating systems for wireless sensor network nodes are typically less complex than general-purpose operating systems. They more strongly resemble embedded systems, for two reasons. First, wireless sensor networks are typically deployed with a particular application in mind, rather than as a general platform.

  5. Image sensor - Wikipedia

    en.wikipedia.org/wiki/Image_sensor

    A micrograph of the corner of the photosensor array of a webcam digital camera Image sensor (upper left) on the motherboard of a Nikon Coolpix L2 6 MP. The two main types of digital image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor), fabricated in complementary MOS (CMOS) or N-type MOS (NMOS or Live MOS) technologies.

  6. Sensor node - Wikipedia

    en.wikipedia.org/wiki/Sensor_node

    The controller performs tasks, processes data and controls the functionality of other components in the sensor node. While the most common controller is a microcontroller, other alternatives that can be used as a controller are: a general purpose desktop microprocessor, digital signal processors, FPGAs and ASICs.

  7. Sensor web - Wikipedia

    en.wikipedia.org/wiki/Sensor_Web

    Sensor web is a type of sensor network that heavily utilizes the World Wide Web and is especially suited for environmental monitoring. [ 1 ] [ 2 ] [ 3 ] OGC 's Sensor Web Enablement (SWE) framework defines a suite of web service interfaces and communication protocols abstracting from the heterogeneity of sensor (network) communication.

  8. Mobile wireless sensor network - Wikipedia

    en.wikipedia.org/wiki/Mobile_wireless_sensor_network

    A mobile wireless sensor network (MWSN) [1] can simply be defined as a wireless sensor network (WSN) in which the sensor nodes are mobile. MWSNs are a smaller, emerging field of research in contrast to their well-established predecessor.

  9. Computer graphics (computer science) - Wikipedia

    en.wikipedia.org/wiki/Computer_graphics...

    Computer graphics is a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. Although the term often refers to the study of three-dimensional computer graphics, it also encompasses two-dimensional graphics and image processing.
