Sentence examples for luminance colour from inspiring English sources

The role of the contrasting pre-treatment in the retina is to rapidly enhance the characteristics (luminance, colour and texture) on the boundaries of the homogeneous zones in a scene in order to improve their perception and extract the features associated to the vital functions like the nutrition, the survival and the reproduction.

First we found that feature congestion (a combination of differentials of luminance, colour and edge orientation) was significantly more predictive of face location in TotTV than ATV.

However, 'second-order' static features such as feature congestion (defined as a combination of differentials of luminance, colour and edge orientation) are thought to play a larger role in influencing gaze allocation during dynamic scene viewing (Rosenholtz, Li & Nakano, 2007).

We then calculated low-level features frame by frame: we calculated two first-order static features (luminance, colour intensity), a second-order static feature (feature congestion) and a first-order dynamic feature (flicker, which approximates motion) (Mital et al., 2010).

First we analysed the mean values of each feature parameter (luminance, colour intensity, feature congestion and flicker) across the entire segment, irrespective of whether that content is located around the face of the speaking character or elsewhere in the frame.

The inversion of an object's canonical orientation is especially used in subtractive neurometabolic paradigms to deprive familiar configurations (such as houses or faces) of their functional properties as visual entities, the overall luminance, colour and spatial frequency features being equal [ 13- 15].

On one hand, they can be considered as lighting techniques and deserve to be characterised through the same type of parameters: illuminances, uniformity, luminances, colour temperature, colour rendering indices, etc.

We separated luminance and colour using the 1976 CIE L*a*b* (CIELAB) colour-space convention (see Figure 2 and Supplementary Methods (SM)).

Perception requires a luminance or colour contrast between target and its background.

This study explored and identified the effects of luminance contrast, colour combinations, font, and search time on brand icon legibility.

The visual stimulus was a checkerboard pattern of black and white squares (15 mm side, 80% contrast, mean luminance 250 colour colour temperature 9500 K) alternating at a frequency of 3.1 Hz.
