2. Histogram equalization - Wikipedia

   en.wikipedia.org/wiki/Histogram_equalization

   This allows for areas of lower local contrast to gain a higher contrast. Histogram equalization accomplishes this by effectively spreading out the highly populated intensity values which are used to degrade image contrast. The method is useful in images with backgrounds and foregrounds that are both bright or both dark. In particular, the ...

3. Luminance HDR - Wikipedia

   en.wikipedia.org/wiki/Luminance_HDR

   Prerequisite of HDR photography are several narrow-range digital images with different exposures. Luminance HDR combines these images and calculates a high-contrast image. In order to view this image on a regular computer monitor, Luminance HDR can convert it into a displayable LDR image format using a variety of methods, such as tone mappin

4. Tone mapping - Wikipedia

   en.wikipedia.org/wiki/Tone_mapping

   Tone mapped high-dynamic-range (HDR) image of St. Kentigerns Roman Catholic Church in Blackpool, Lancashire, England, UK. Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images in a medium that has a more limited dynamic range.

5. Reverse-contrast typefaces - Wikipedia

   en.wikipedia.org/wiki/Reverse-contrast_typefaces

   The contrast has been increased and the axis of the contrast made more purely vertical. A conventional slab-serif typeface, Rockwell. [c] The serifs have been thickened and the contrast is minimal. Starting in the seventeenth century, typefounders developed what are now called transitional and then "modern" or Didone types. These typefaces had ...

6. Contrast (vision) - Wikipedia

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

   Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) visible against a background of different luminance or color. [1] The human visual system is more sensitive to contrast than to absolute luminance; thus, we can perceive the world similarly despite significant changes in ...

7. Normalization (image processing) - Wikipedia

   en.wikipedia.org/wiki/Normalization_(image...

   The basic intent of the contrast enhancement technique is to adjust the local contrast in the image so as to bring out the clear regions or objects in the image . Low-contrast images often result from poor or non-uniform lighting conditions, a limited dynamic range of the imaging sensor , or improper settings of the lens aperture.
