  2. Grayscale - Wikipedia

    en.wikipedia.org/wiki/Grayscale

    Grayscale images have many shades of gray in between. Grayscale images can be the result of measuring the intensity of light at each pixel according to a particular weighted combination of frequencies (or wavelengths), and in such cases they are monochromatic proper when only a single frequency (in practice, a narrow band of frequencies) is ...

  3. SMPTE color bars - Wikipedia

    en.wikipedia.org/wiki/SMPTE_color_bars

    In a SMPTE color bar image, the top two-thirds of the television picture contain seven vertical bars of 75% intensity. In order from left to right, the colors are white or gray, yellow, cyan, green, magenta, red, and blue. [18] The choice of white or gray depends on whether that bar's luminance is 100% or not.

  4. Co-occurrence matrix - Wikipedia

    en.wikipedia.org/wiki/Co-occurrence_matrix

    A co-occurrence matrix or co-occurrence distribution (also referred to as : gray-level co-occurrence matrices GLCMs) is a matrix that is defined over an image to be the distribution of co-occurring pixel values (grayscale values, or colors) at a given offset. It is used as an approach to texture analysis with various applications especially in ...

  5. Color normalization - Wikipedia

    en.wikipedia.org/wiki/Color_normalization

    The grey world normalization makes the assumption that changes in the lighting spectrum can be modelled by three constant factors applied to the red, green and blue channels of color. [6] More specifically, a change in illuminated color can be modelled as a scaling α, β and γ in the R, G and B color channels and as such the grey world ...

  6. Image resolution - Wikipedia

    en.wikipedia.org/wiki/Image_resolution

    Image resolution is the level of detail of an image. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail. Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to ...

    en.wikipedia.org/wiki/Grey

    Grey (more frequent British English) or gray (more frequent American English) [2] is an intermediate color between black and white. It is a neutral or achromatic color, meaning that it has no chroma and therefore no hue. [3] It is the color of a cloud-covered sky, of ash, and of lead. [4]

    For narrow range color, 10-bit per sample signals use video levels where the black level is defined as 64, achromatic gray level as 512 and the nominal peak as 940 in RGB, Y, and I encoding and 960 in Cb/Cr, and Ct/Cp component encoding. 12-bit per sample signals define 256 as the black level, 2048 as the gray level and the nominal peak is 3760 ...
