Sentence examples for contrast luminance from inspiring English sources

The model is a weighted sum of six features characterizing text: chromatic contrast, luminance contrast, font size, letter spacing, line height and word spacing.

We combine these measures (contrast, luminance) into a weight map using multiplication (AND) operation.

The values of contrast, luminance and saturation measures for the contrast-enhanced images are presented in Table 2.

The performance of the proposed method is evaluated using visual assessment and quantitative measures for contrast, luminance and saturation.

The present algorithm includes four kinds of parameters of,,, and, which control contrast, luminance, and edge preservation by the multiple bilateral filtering parameters, respectively.

Figure 15 (a) Original image (b-e) Comparison of fused images with contrast, saturation, luminance and contrast, luminance and saturation measures, respectively, to compute the weight map.

Contrast and luminance were chosen from a palette to yield approximately equal full dominance intervals for the two percepts and were relatively high (standard colours in Adobe Illustrator ©).

Here, we tested whether area V6 responded to high-contrast (100% luminance contrast) 5-Hz luminance flicker with square contrast modulation in time (code by G. Galati).

The lighting performance issues examined by detailed simulations were direct sunlight, horizontal illuminance levels and artifact exposure, diversity and uniformity of illuminance, and contrasting luminances in the field of view.

These studies suggest that the mammalian visual system reproduces the contrast-luminance independence of natural images with high precision.

The effect was mainly subtractive and subsided in approximately 400 ms. We suggest that the failure of contrast-luminance independence under simultaneous changes of both parameters reflects the fact that luminance adaptation in the retina cannot be instantaneous.
