The lightness of a test stimulus depends in a complex manner on the context in which it is
viewed. To predict lightness, it is necessary to leverage measurements of a feasible number …

The class of all natural images is an extremely small fraction of all possible images. Some of
the structure of natural images can be modeled statistically, revealing striking regularities …

Gratings that contain luminance and chromatic components of different spatial frequencies
were used to study the segregation of signals in luminance and chromatic pathways …

The first step in the evolution of primate trichromatic color vision was the expression of a
third cone class not present in ancestral mammals. This observation motivates a …

The statistics of natural images have attracted the attention of researchers in a variety of
fields and have been used as a means to better understand the human visual system and its …

We have developed a protocol for testing experimentally the hypothesis that the human
visual system is optimised for making visual discriminations amongst natural scenes. Visual …

Object recognition by natural and artificial visual systems benefits from the identification of
object boundaries. A useful cue for the detection of object boundaries is the superposition of …

Multi-spectral images are becoming more common in industrial inspection tasks where the
colour is used as a quality measure. In this paper we propose a spectral cooccurrence …

La connaissance des principes et des mécanismes de la perception humaine de la couleur
permet de mettre en œuvre des techniques de reproduction et de traitement industriels de la …

The optimal spectral profiles of lighting for naturalness, individual preference, and chromatic
diversity were estimated with psychophysical experiments in which observers selected …
