Then, the speed difference and the same
sensitivity function are determined.
Objectives: To assess and compare contrast
sensitivity function in the previously amblyopic and non-amblyopic "normal" eyes of patients with microtropia and anisometropia who achieved 20/20 visual acuity after occlusion therapy.
It is through this contrast
sensitivity function that the visual system obtains the information from the input image of the stimulus in the frequency domain.
The overall design of the controller is concerned with shaping the loop gain, C(s)P(s), for the controller, C(s), and the plant, P(s) to make the
sensitivity function, S(s), control
sensitivity function, R(s), and complementary
sensitivity function, T(s), as small as possible for the system.
The prediction was improved when the residuals were weighted to take account of the greater sensitivity to mid-range spatial frequencies, as in a published estimate of the contrast
sensitivity function.
The lowest sinusoidal spatial frequency works best due to the contrast sensitivity characteristics per the Contrast
Sensitivity Function (CSF) of the human eye; however the tradeoff is the amount of intrusion into the active area of the display.
Thus, the contrast
sensitivity function (CSF) represents the CS for a set of spatial frequency bands low, medium and high (De Valois & De Valois, 1988).
Mesopic radial frequency contrast
sensitivity function for young and older adults.
Thus, the Barten SQRI is calculated based on measurable properties of the visual displays and the contrast
sensitivity function (CSF) of the person.
Contrast
sensitivity function (CSF) is one of the most important measures of visual system performance [13] which is determined according to a person's ability to discriminate luminance [14], (luminance or achromatic contrast sensitivity) or color differences [15] (chromatic contrast sensitivity), resulting from the interaction of black-white, blue-yellow, and red-green opponent channels.
They provide a spectral
sensitivity function for lipofuscin that also peaks at blue wavelengths, but extends to longer wavelengths than the older blue hazard spectral
sensitivity function mentioned above.
International Commission on Illumination (CIE) in 1931 has introduced human eye
sensitivity function V([lambda]), which was modified in 1978 (Fig.
