For increasing the contrast of such images, the transformation curve needs to be spread out the dark intensities to the higher intensities.
Any original image (e.g., Figure 1) is preprocessed for increasing the contrast of pulp fibroblasts relative to the extracellular matrix.
For low-contrast bright images (μ≥0.5), the major concern is to increase the contrast for better distinguishability of the image details that are made up of high intensities.
Only the 420 nm pigment is used for sun compass orientation, which may be an adaptation for increasing the contrast between the sun and background scattered skylight or for detecting the radiance distribution of skylight.
For increasing the contrast in this type of images, the transformation curve should spread out the bright intensities over a wider range of darker intensities.
The basic need for preprocessing in mammographic images is to increase the contrast, especially for dense breasts.
(Specifically, the app increases the contrast optimizing for white point, sharpens the image and increases the color saturation, if you must know).
In order to visualize the roots, we had to increase the contrast above that needed for optimal visualization of the stem.
In our recent study on deception, increased neuronal activity was observed mainly in the dorsolateral prefrontal cortex during lie-telling compared to truth-telling, and as the capacity for deception increased, the contrast between brain activities (lie vs. truth) decreased [ 7].
As for the development temperature, it is well known that generally cold development improves the positive resist contrast and resolution [18, 20], whereas hot development increases the contrast for negative resists like HSQ [21].
