There are individual differences in color vision. It is difficult for a person with defective cones in the retina to recognize the difference of specific colors. We propose a presentation method of color information by using a projector camera system. The system projects border lines or color names on real object surfaces when they have specific color combinations. Effectiveness of the proposed...

Mapping the distribution of more than one macromolecule in a tissue is now a relatively routine technique that uses multiple-label fluorescence (2,7) and one of several different digital imaging methods (9,10), including wide-field, confocal, deconvolution, or multiple-photon microscopy. Methods of specimen preparation continue to be refined, especially as new fluorescent probes are developed a...

People associate basic tastes (e.g., sweet, sour, bitter, and salty) with specific colors (e.g., pink or red, green or yellow, black or purple, and white or blue). In the present study, we investigated whether a color bordered by another color (either the same or different) would give rise to stronger taste associations relative to a single patch of color. We replicate previous findings, highli...

Representations of target-defining features (attentional templates) guide the selection of target objects in visual search. We used behavioral and electrophysiological measures to investigate how such search templates control the allocation of attention in search tasks where targets are defined by the combination of 2 colors or by a specific spatial configuration of these colors. Target display...

We investigated the low-level motion mechanisms for color and luminance and their integration process using 2D and 3D motion aftereffects (MAEs). The 2D and 3D MAEs obtained in equiluminant color gratings showed that the visual system has the low-level motion mechanism for color motion as well as for luminance motion. The 3D MAE is an MAE for motion in depth after monocular motion adaptation. A...

Studying aesthetic preference is notoriously difficult because it targets individual experience. Eye movements provide a rich source of behavioral measures that directly reflect subjective choice. To determine individual preferences for simple composition rules we here use fixation duration as the fitness measure in a Gaze Driven Evolutionary Algorithm (GDEA), which has been demonstrated as a t...

We developed a very low bit rate watercolor-like video form, which is constructed with a bi-level Y luminance component and a number of UV chrominance combinations. The bi-level Ycomponent outlines the features of an image and the UVcombinations describe the basic color information of the image. The UV combinations are dynamically chosen during encoding. The resultant video looks better than bi...
