This book examines contrast sensitivity of the human visual system--concerning the eye's ability to distinguish objects from each other or from the background--and its effects on the image-forming process. The text provides equations for determining various aspects of contrast sensitivity, in addition to models (mathematical expressions) that can easily be adapted for practical applications.With an exponential relation between the input and the output luminance, the output modulation depends on the luminance in the concerning part of the image. If gamma is higher than one, local luminance differences increase in light parts of anbsp;...
