  2. Contrast (vision) - Wikipedia

    en.wikipedia.org/wiki/Contrast_(vision)

    For example, in the case of graphical computer displays, contrast depends on the properties of the picture source or file and the properties of the computer display, including its variable settings. For some screens the angle between the screen surface and the observer's line of sight is also important.

  3. Visual comparison - Wikipedia

    en.wikipedia.org/wiki/Visual_comparison

    Visual comparison with a standard chart or reference is often used as a means of measuring complex phenomena such as the weather, sea states or the roughness of a river. [4] A colour chart is used for this purpose in many contexts such as chemistry , cosmetics , medical testing and photography .

  4. Structural similarity index measure - Wikipedia

    It has found use in analyzing human response to contrast-detail phantoms. [18] SSIM has also been used on the gradient of images, making it "G-SSIM". G-SSIM is especially useful on blurred images. [19] The modifications above can be combined. For example, 4-G-r* is a combination of 4-SSIM, G-SSIM, and r*.

  5. Adaptive histogram equalization - Wikipedia

    en.wikipedia.org/wiki/Adaptive_histogram...

    Adaptive histogram equalization (AHE) is a computer image processing technique used to improve contrast in images. It differs from ordinary histogram equalization in the respect that the adaptive method computes several histograms, each corresponding to a distinct section of the image, and uses them to redistribute the lightness values of the image.

    Edges can include obvious perceptions such as the edge of a house, and can include other perceptions that the brain needs to process deeper, such as the edges of a person's facial features. When finding edges, the brain's visual system detects a point on the image with a sharp contrast of lighting.

    In contrast, organic shapes are free-form, unpredictable, and flowing in appearance. These shapes and organic forms visually suggest the natural world of animals, plants, sky, sea, etc... The addition of organic shapes to a composition dominated by geometric structures can add unpredictable energy.
