Abstract

Reflected illumination from a surface provides a variety of information about material perception. A precisely designed illumination projection with a video projector changes the reflected illumination, and it manipulates our material perception, apart from the apparent texture and color. In this paper, several works on perceptual material appearance manipulation that employ projector-camera systems are presented. Psychophysics-based image processing algorithms that utilize co-axial optical configuration facilitate successive manipulation. In our latest work, viewing-direction-dependent appearance manipulation using light-field projection on an anisotropic reflection surface is proposed for advanced material perception manipulation.
