  3. Video quality - Wikipedia

    en.wikipedia.org/wiki/Video_quality

    Video quality is a characteristic of a video passed through a video transmission or processing system that describes perceived video degradation (typically compared to the original video). Video processing systems may introduce some amount of distortion or artifacts in the video signal that negatively impact the user's perception of the system.

    Movie Maker 2009 supported both Windows Vista and Windows 7. As the previous version of Windows Movie Maker was no longer included with the operating system, the only way to obtain Movie Maker on Windows 7 and later was through the Windows Live Essentials suite, [6] [13] although some manufacturers pre-installed the application on new PCs.

    [7] [4] Other common symptoms are palinopsia, enhanced entoptic phenomena, photophobia, and tension headaches. [10] [11] The condition is typically always present and has no known cure, as viable treatments are still under research. [12] Astigmatism, although not presumed connected to these visual disturbances, is a common comorbidity.

  6. Film grain - Wikipedia

    en.wikipedia.org/wiki/Film_grain

    Granularity, or RMS granularity, is a numerical quantification of density non-uniformity, equal to the root-mean-square (rms) fluctuations in optical density, [5] measured with a microdensitometer with a 0.048 mm (48-micrometre) diameter circular aperture, on a film area that has been exposed and normally developed to a mean density of 1.0 D (that is, it transmits 10% of light incident on it).

  7. Signal-to-noise ratio - Wikipedia

    en.wikipedia.org/wiki/Signal-to-noise_ratio

    In audio engineering, the reference signal is usually a sine wave at a standardized nominal or alignment level, such as 1 kHz at +4 dBu (1.228 V RMS). SNR is usually taken to indicate an average signal-to-noise ratio, as it is possible that instantaneous signal-to-noise ratios will be considerably different.

  8. Speckle (interference) - Wikipedia

    [7] [8] The average is the incoherent average of the looks. [ 8 ] A second method involves using adaptive and non-adaptive filters on the signal processing (where adaptive filters adapt their weightings across the image to the speckle level, and non-adaptive filters apply the same weightings uniformly across the entire image).
