2. Contrast (vision) - Wikipedia

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

   Contrast sensitivity is typically expressed as the reciprocal of the threshold contrast for detection of a given pattern (i.e., 1 ÷ contrast threshold). [15] Using the results of a contrast sensitivity exam, a contrast sensitivity curve can be plotted, with spatial frequency on the horizontal, and contrast threshold on the vertical axis.

3. Histogram equalization - Wikipedia

   en.wikipedia.org/wiki/Histogram_equalization

   The goal of these methods, especially MBOBHE, is to improve the contrast without producing brightness mean-shift and detail loss artifacts by modifying the HE algorithm. [ 1 ] A signal transform equivalent to histogram equalization also seems to happen in biological neural networks so as to maximize the output firing rate of the neuron as a ...

4. 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.

   If the contrast (not the luminance) increases, then both fast and slow channels will increase their firing rate, ideally by the same amount. [ 3 ] [ 11 ] In the model, however, non-linearity creeps in, and the advantages of fast channels increase with more contrast than slow channel acquisition.

6. Diffusion-weighted magnetic resonance imaging - Wikipedia

   en.wikipedia.org/wiki/Diffusion-weighted...

   When water is in an environment where it can freely tumble, relaxation tends to take longer. In certain clinical situations, this can generate contrast between an area of pathology and the surrounding healthy tissue. To sensitize MRI images to diffusion, the magnetic field strength (B1) is varied linearly by a pulsed field gradient.
