In this paper, we propose an efficient algorithm for the measure of contrast in digital images.
It applies locally, at various sub-sampled levels, a simplified computation of local contrast …

The integration of visual information is a critical task that is performed by neurons in the
extrastriate cortex of the primate brain. For motion signals, integration is complicated by the …

We have measured the relationship between image contrast, perceived contrast, and BOLD
fMRI activity in human early visual areas, for natural, whitened, pink noise, and white noise …

We characterised the impact of spatial frequency and contrast on saccade latencies to single
Gabor patches. Saccade latencies decreased as a function of contrast, and increased with …

Asymmetric lightness matching was employed to measure how the visual system assigns
lightness to surface patches seen through partially-transmissive surfaces. Observers …

The paper addresses the issue of perceptual image quality assessment. By using Bayesian
networks, we propose a Bayesian composed quality measure (B-CQM). This metric can …
