The human color and luminance-driven systems appear to be mediated by mechanisms with
distinct spatio-temporal tuning properties, with the iso-luminant color-driven system …

We have investigated the spatial transfer characteristics of the mechanisms sensitive to color
in the human visual system using a method of simultaneous spatial masking with …

The spatial and temporal properties of human colour vision are examined using isoluminant,
red–green and blue–yellow tritanopic gratings. Chromatic sensitivity is found to be low-pass …

Purpose: Cross-orientation masking (XOM) is defined psychophysically as the phenomenon
whereby detection of a test grating is masked by the presence of a superimposed stimulus at …

Color vision in humans starts with three types of cones (short [S], medium [M], and long [L]
wavelengths) in the retina and three retinal and subcortical cardinal mechanisms, which …

Detection of a Gabor pattern is impaired in the presence of a similar pattern of orthogonal
orientation, a phenomenon known as cross-orientation masking (XOM). Here we investigate …

In natural viewing, an object's background often changes over time. Temporally varying
backgrounds were investigated here with a steady test field within a time-varying …

The color appearance of a physically steady central region can appear to vary over time if a
surrounding chromatic light varies in time. The induced temporal variation, however, is …

In many elementary textbooks of science, color is defined as a physical property of matter.
Although that notion is misleading, it does have some truth in it because color is a visual …

Human vision is able to discriminate chromatic from achromatic changes under a wide
variety of spatiotemporal conditions. Objectively, we distinguish physically between a light …
