Lightness, brightness, and brightness contrast: 1. Illuminance variation.
Changes of annulus luminance in traditional disk-and-annulus patterns are perceptually ambiguous; they could be either reflectance or illuminance changes. In more complicated patterns, apparent reflectances are less ambiguous, letting us place test and standard patches on surrounds perceived to be different grays. Our subjects matched the apparent amounts of light coming from the patches (brigh...
متن کاملVisual acuity during direct laryngoscopy at different illuminance levels.
BACKGROUND Adequate light is essential for vision during direct laryngoscopy. The ISO 7376:2009 standard specifies the minimal illuminance for laryngoscopes. No studies have objectively examined the relationship between laryngoscope illumination and visual acuity during laryngoscopy. METHODS We measured the near visual performance of 50 anesthesiologists during direct laryngoscopy using near ...

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
Levels of Brightness Perception
Most vision scientists are comfortable with the idea that perception is a multi-level process. For example we take it for granted that the two best understood properties of human colour vision, trichromacy and colour-opponency, are underpinned by physiological mechanisms operating at different stages in the visual pathway. The observation that any colour can be matched by a suitable mixture of ...
متن کاملSummarizing Texts at Various Levels of Detail
Summarizing document texts at various levels of detail is required for many information selection tasks. For instance, when loading and visualizing documents on small screens of handheld devices, it is important to be able to dynamically compress texts. In this article we discuss a technique of generating hierarchical topic trees of a text and to use them in various ways to build summaries of a...
