2. Blend modes - Wikipedia

   en.wikipedia.org/wiki/Blend_modes

   The Luminosity mode is commonly used for image sharpening, because human vision is much more sensitive to fine-scale lightness contrast than color contrast. (See Contrast (vision) ) Few editors other than Photoshop implement this same color space for their analogs of these blend modes. [ 3 ]

4. Astronomical filter - Wikipedia

   en.wikipedia.org/wiki/Astronomical_filter

   Filters can be used to increase contrast and enhance the details of the Moon and planets. All of the visible spectrum colors each have a filter, and every color filter is used to bring a certain lunar and planetary feature; for example, the #8 yellow filter is used to show Mars's maria and Jupiter's belts .

5. Histogram equalization - Wikipedia

   en.wikipedia.org/wiki/Histogram_equalization

   This method usually increases the global contrast of many images, especially when the image is represented by a narrow range of intensity values. Through this adjustment, the intensities can be better distributed on the histogram utilizing the full range of intensities evenly. This allows for areas of lower local contrast to gain a higher contrast.

6. 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.

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.

9. Edge enhancement - Wikipedia

   en.wikipedia.org/wiki/Edge_enhancement

   Edge enhancement is an image processing filter that enhances the edge contrast of an image or video in an attempt to improve its acutance (apparent sharpness).. The filter works by identifying sharp edge boundaries in the image, such as the edge between a subject and a background of a contrasting color, and increasing the image contrast in the area immediately around the edge.
