The environments in which we live and the tasks we must perform to survive and reproduce
have shaped the design of our perceptual systems through evolution and experience …

Color has been scientifically investigated by linking color appearance to colorimetric
measurements of the light that enters the eye. However, the main purpose of color …

Hyperspectral images provide higher spectral resolution than typical RGB images by
including per-pixel irradiance measurements in a number of narrow bands of wavelength in …

Throughout their lives animals must complete many tasks, including finding food, avoiding
predators, attracting mates, and navigating through a complex and dynamic environment …

In understanding how visual signals function, quantifying the components of those patterns
is vital. With the ever-increasing power and availability of digital photography, many studies …

Effective camouflage renders a target indistinguishable from irrelevant background objects.
Two interrelated but logically distinct mechanisms for this are background pattern matching …

Colour vision allows animals to reliably distinguish differences in the distributions of spectral
energies reaching the eye. Although not universal, a capacity for colour vision is sufficiently …

Visual coding is a highly dynamic process and continuously adapting to the current viewing
context. The perceptual changes that result from adaptation to recently viewed stimuli …

We present an algorithm for separating the shading and reflectance images of
photographed natural scenes. The algorithm exploits the constraint that in natural scenes …

Evading detection by predators is crucial for survival. Camouflage is therefore a widespread
adaptation, but despite substantial research effort our understanding of different camouflage …
