In Renaissance poetry, and particularly in sonnets, the contrast was similarly used as a poetic argument. In such verse, the entire poem argues that two seemingly alike or ...
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.
A contrast is defined as the sum of each group mean multiplied by a coefficient for each group (i.e., a signed number, c j). [10] In equation form, = ¯ + ¯ + + ¯ ¯, where L is the weighted sum of group means, the c j coefficients represent the assigned weights of the means (these must sum to 0 for orthogonal contrasts), and ¯ j represents the group means.

The "luminance contrast" is the ratio between the higher luminance, L H, and the lower luminance, L L, that define the feature to be detected.This ratio, often called contrast ratio, CR, (actually being a luminance ratio), is often used for high luminances and for specification of the contrast of electronic visual display devices.
MRI contrast agents may be administered by injection into the blood stream or orally, depending on the subject of interest. Oral administration is well suited to gastrointestinal tract scans, while intravascular administration proves more useful for most other scans. MRI contrast agents can be classified [2] by their: Chemical composition
Contrast is often overtly marked by markers such as but or however, such as in the following examples: ... contrast is a major discourse relation, ...
Behavioral contrast refers to a change in the strength of one response that occurs when the rate of reward of a second response, or of the first response under different conditions, is changed. For example, suppose that a pigeon in an operant chamber pecks a key for food reward.
In music and musical form, contrast is the difference between parts or different instrument sounds. The three types of contrast are rhythmic contrast, melodic contrast, and harmonic contrast. [1] Procedures of contrast include stratification, juxtaposition, and interpolation. Procedures of connection include gradation, amalgamation, and ...
