Luminance and Contrast for Sign Legibility and Color Recognition
A laboratory study of sign legibility has shown that a contrast of between 30 and 50 percent is required to maintain 75th percentile legibility. Legibility distance increased gradually with greater contrast to about 80 percent; above a luminance ratio of 5 to 1, legibility did not increase greatly. As ambient levels increased, legibility distance increased linearly with the logarithm of either ...
متن کاملFactors affecting visibility of a target tissue in histologic sections.
The objective of histologic techniques is to stain the subject with high specificity and high visibility. Visibility depends on the microscope's resolution and contrast and on the microscopist's skill at optimizing the microscope's image. It also depends on histotechnological factors, which include specificity and differentiation of the stain, density of background staining (particularly in sil...

15 صفحه اولFactors Affecting Detectability of River Otters During Sign Surveys
Sign surveys are commonly used to study and monitor wildlife species but may be flawed when surveys are conducted only once and cover short distances, which can lead to a lack of accountability for false absences. Multiple observers surveyed for river otter (Lontra canadensis) scat and tracks along stream and reservoir shorelines at 110 randomly selected sites in eastern Kansas from January to ...
متن کاملFourier Techniques for Optimizing Symbol Highway Sign Legibility
Symbol (i.e.,"pictorial") highway signs yield legibility distances which are on average twice as great as those achieved for their text sign counterparts. Howevcr. the relative superiority of symbl signs is neither uniform nor universal. Some symbol signs are legible from 3-times as far away while other p r l y designed symbol signs can be recognized at only half the distance of their textual e...
