It is still unclear how well anomalous trichromats discriminate natural colors and whether
commercial spectral filters improve performance in these conditions. We show that …

Vivid warning signals (aposematism) have evolved repeatedly throughout the animal
kingdom. However, relatively few studies consider what makes an effective signal, in terms …

This review of color processing in natural image viewing–rather than artificial laboratory
images–addresses the role of color edges. Much of the color variation in nature is a result of …

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 …

Cuando mis circunstancias laborales, el destino o como quieran llamarlo me volvieron a
poner en contacto con el profesor Juan Luis Nieves Gómez, tras casi 20 años de nuestra …

We introduce a theoretical framework for measuring the information content in the edges
extracted from a color image. The main difficulty in estimating the amount of information …

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 …

La influencia de la distribución de potencia espectral (SPD) de la iluminación en la
apariencia del color de escenas, tanto naturales como artificiales, ha sido puesta de …
