Hence, the iris controls the amount of light entering the eye by adjusting the size of pupil. Example If light is bright, it reduces the size of Pupil,so that less light can enter the eyes If light is dim, it increases the size of the pupil so that more light can enter our eyes...
Pairs of brightness functions were generated by magnitude estimation, one pair for each of three flash durations (0.5,1.0, and 3.0 sec). Each pair comprised a function obtained with an artificial pupil and a function obtained with the uncontrolled natural pupil. The pupil turned out to have ...

Indenotes the intensity measurement of n-th low-resolution image. F†denotes the inverse Fourier transfrom. Pdenotes the pupil function of the image system. Mndenotes the selection mask for n-th LED illumination. Whenγ=1the fidelity term uses intensity measurement, while forγ=0.5the fidelity...
Modulation transfer function (MTF) and the phase transfer function (PTF) were measured in water at room temperature with white light and for a wide range of pupil diameters (2, 3, 4, and 5 mm). The IOLs were measured in a custom made physical model eye [8] that follows the a ISO ...
Carrying inward to a central organ or section, as nerves that conduct impulses from the periphery of the body to the brain or spinal cord. [Latinafferēns, afferent-, present participle ofafferre,to bring toward:ad-,ad-+ferre,to bring; seebher-inIndo-European roots.] ...
The magnitude of student self-disclosure scores was a direct function of the positiveness of teacher verbal behavior. Nonverbal behavior also influenced self-disclosure, interacting with student sex. This effect varied across individual teachers, however, and no consistent pattern was evident. 展开 ...
The function of these incisions is thought to be manifold: they serve the aesthetic purpose of marking children as “Hadza,” and they allow for the application of medicines when treating injuries and ailments42,43,44. Intentional scarification for purposes of beautification and rites of practice ...
