Abstract
In computer vision applications, analysis of shading information
requires a proper model of light reflection from object surfaces. To
overcome the shortcoming of the most often used model and to extend the
reflection model for computer color vision, an examination is made of
the light reflection problem using the bidirectional
spectral-reflectance distribution function (BSRDF) to specify both
incident- and reflected-beam geometries. It is shown that the product
form can still be retained for a polychromatic light source under two
lighting conditions: the light source is collimated; or the spectral
factor and the geometric factor can be separated for both the light
source and the BSRDF of the surface. The reflection model is then
applied to the formulation of a neutral-interface-reflection model,
which is tested experimentally. The results show the adequacy of this
type of model for surfaces of some material compositions, e.g. plastics,
plant leaves, painted surfaces, orange peels, and some glossy cloth, but
not for others, e.g. colored paper and some ceramics
