Effect of luminance on suprathreshold contrast perception.
Perceived contrast was measured under natural viewing conditions with the use of contrast-matching and magnitude-estimation paradigms and found to be independent of luminance over a range of luminances from 37.5 down to 8 cd/m2. However, this contrast constancy broke down when the dimmer target was below 8 cd/m2. The perceived contrast of the dimmer target then fell below that expected from con...
متن کاملEffect of Contrast on the Quality of 3D Visual Perception
There are several different factors that affect the perceived quality of 3D content. Our objective in this paper is to study how the change of contrast between the objects of interest and the background in a scene will affect the overall 3D visual perception. For this study, we captured outdoor and indoor scenes in 3D format. For each scene, the brightness of the background was consistent and t...
متن کاملEfficient Contrast Effect Compensation with Personalized Perception Models
Color is one of the most effective visual variables and is frequently used to encode metric quantities. Contrast effects are considered harmful in data visualizations since they significantly bias our perception of colors. For instance, a gray patch appears brighter on a black background than on a white background. Accordingly, the perception of color-encoded data items depends on the surround ...
متن کاملAnswers to the Perception of Thematic Contrast and Questions regarding the Perception of Thematic “Non-Contrast”
In a previous production study [1] we explored the prosodic marking of thematic material in contrastive and non-contrastive contexts in German. While both conditions resulted in a prenuclear rise, we found that themes in contrastive context exhibited a significantly longer stressed vowel, together with a higher and later peak. Interestingly, speakers varied as to whether they used peak alignmen...
متن کاملProduction and Perception of Contrast in German
In German intonational phonology two different approaches to model nuclear falling accents exist (cf. [6, 8] vs. GToBI [11]). While [6] and [8] assume only left-headed pitch accents, the GToBI system allows for leftand right headedness. Consequently, in the former approach one simple falling accent (H*L) is represented in the tonal grammar while GToBI distinguishes between two falling accents, ...
