Sentence examples for perception of brightness from inspiring English sources

Intriguingly, this subjective perception of brightness significantly predicted their increased occipital SWA throughout the sleep episode.

However, for the two stimulus sets in which the harmonic part is most prevalent, that is, sets A1 and B, the perception of brightness seems to depend on the harmonic proportion.

The perception of brightness depends on spatial context: the same stimulus can appear light or dark depending on what surrounds it.

The HK effect, like its close relations – simultaneous brightness contrast, the Hunt effect and the Abney effect – is an example of how the human perception of brightness is not a direct mapping of a light stimulus.

Photometry, a perception of brightness as seen by the human eye, is performed with a lux meter in units called lux.

The paradox is that if the intensity in one eye is 10%15%15% or less of the intensity in the other, lowering that intensity further results in increased perception of brightness (Fechner, 1861; Levelt, 1965).

The 6500 K lamp was effective at increasing perceptions of brightness in offices with the lower ambient light level.

The data suggest that perceptions of brightness represent a robust visual response to the likely sources of stimuli, as determined, in this instance, by the known statistical relationship between scenes and their retinal responses.

When this evidence is combined with the success of an empirical framework in predicting other puzzling aspects of motion perception [2], [3], as well as perceptions of brightness, color, and geometric form [9] [11], a different concept of visual experience and its underlying mechanism emerges.

At lower levels, the human perception of reduced brightness as a percentage is provided by the following formula: \text{perceived reduction}\% = 100 \times \sqrt{\text{actual reduction}\% \over 100} When the actual reduction is 1.00 / 1.30, or about 0.770, the perceived reduction is about 0.877, or 1.00 / 1.14.

In the experiments described below, we first build a simple model of natural scenes, retinal responses ('images') and predicted reflectances ('perception'), and show that it corresponds to human perception of the brightness of colours.
