  2. Vectorscope - Wikipedia

    en.wikipedia.org/wiki/Vectorscope

    A video vectorscope displaying color bars. The diagonal direction of the colorburst vector is indicative of a PAL signal. The graticule of an NTSC vectorscope. A PAL vectorscope displaying color bars. A vectorscope is a special type of oscilloscope used in both audio and video applications. [1]

  3. Eye pattern - Wikipedia

    en.wikipedia.org/wiki/Eye_pattern

    The first step of computing an eye pattern is normally to obtain the waveform being analyzed in a quantized form. This may be done by measuring an actual electrical system with an oscilloscope of sufficient bandwidth, or by creating synthetic data with a circuit simulator in order to evaluate the signal integrity of a proposed design.

  4. Waveform monitor - Wikipedia

    en.wikipedia.org/wiki/Waveform_monitor

    The level of a video signal usually corresponds to the brightness, or luminance, of the part of the image being drawn onto a regular video screen at the same point in time. A waveform monitor can be used to display the overall brightness of a television picture, or it can zoom in to show one or two individual lines of the video signal.

  5. Computer vision - Wikipedia

    en.wikipedia.org/wiki/Computer_vision

    Computer vision is an interdisciplinary field that deals with how computers can be made to gain high-level understanding from digital images or videos.From the perspective of engineering, it seeks to automate tasks that the human visual system can do.

  6. P300 (neuroscience) - Wikipedia

    en.wikipedia.org/wiki/P300_(neuroscience)

    The P300 wave obtained by visual stimulation is used to assess cognitive processes in humans, and the value of the latency and amplitude of the P300 wave can be a measure of the severity of dementia processes. [21] The analysis of P300 wave latency seems to be particularly useful in the diagnosis of mild cognitive impairment (MCI). [22]

  7. Videonystagmography - Wikipedia

    en.wikipedia.org/wiki/Videonystagmography

    The patient wears goggles containing a camera that tracks the pupils using infrared imaging; the video eye-tracking system records and sends pupil movement tracings to a computer typically with VNG analysis software. [1] [2] [3] The goggles may also have a cover in order to deny vision for some tests while still recording eye movement. There ...

  8. Modulation - Wikipedia

    en.wikipedia.org/wiki/Modulation

    For example, the modulation signal might be an audio signal representing sound from a microphone, a video signal representing moving images from a video camera, or a digital signal representing a sequence of binary digits, a bitstream from a computer. This carrier wave usually has a much higher frequency than the message signal does. This is ...

  9. Biological computing - Wikipedia

    en.wikipedia.org/wiki/Biological_computing

    A more restrictive definition views nanobiotechnology more specifically as the design and engineering of proteins that can then be assembled into larger, functional structures [2] [3] The implementation of nanobiotechnology, as defined in this narrower sense, provides scientists with the ability to engineer biomolecular systems specifically so ...
