Despite the global and local daylight changes naturally occurring in natural scenes, the
human visual system usually adapts quite well to those changes, developing a stable color …

Image contrast, such as luminance and color contrast, represent important information in
object recognition. But the object colors depend also on both the spectral reflectance of the …

Essential to sensory processing in the human visual system is natural illumination, which
can vary considerably not only across space but also along the day depending on the …

An appropriate exposure to the light-dark cycle, with high irradiances during the day and
darkness during the night is essential to keep our physiology on time. However, considering …

The correlated colour temperature (CCT) is defined by the closest point on the Planckian
locus from a light source on the CIE 1960 (u, v) diagram (now obsolete), while the current …

Temporal changes in illumination are ubiquitous; natural light, for example, varies in color
temperature and irradiance throughout the day. Yet little is known about human sensitivity to …

The distribution of colors in natural images can vary widely across different environments or
within the same environment over time. We have examined how color distributions at a …

In vision science, it is presumed that daylight priors affect color, shape, and light perception.
Earth-Sun geometry, weather, climate, and optical effects such as Rayleigh scattering cause …

Color signal changes with change in illuminant information. This study focuses on estimating
color signals at different Correlated Color Temperature (CCT) of daylight. We selected a set …
