Contrast Sensitivity of the Human Eye and Its Effects on by Peter G. J. Barten

By Peter G. J. Barten

Examines distinction sensitivity of the human visible system--concerning the eye's skill to differentiate items from one another or from the background--and its results at the image-forming technique. The textual content offers equations for picking a number of elements of distinction sensitivity, as well as versions (mathematical expressions) that may simply be tailored for functional applications.
