Specular

Having the reflective properties of a mirror. This means that any incident light will be reflected in the mirror angle direction. Most surfaces are a mix between a specular and lambertian surface.

From the geometry of the specular reflection pattern it may be shown that the surface and dive angles may be computed from the positions of the two light intensity peaks [[phi].sub.1] and [[phi].sub.2] using (Matthews and Soest 1986):
If coating B is darker than A, and coating C looks intense greenish-yellow (Pictures 7 and 8) or reddish-gold, this correlates to 450 illumination and -15 or 150 away from specular viewing, which is closest to the geometry of commonly used multi-angle spectrophotometers.
[16], which selects an optimal exposure time as large as possible and meanwhile avoids image saturation in regions of specular reflection during the process of phase shifting.
The UK-DMC measurements were made when the specular reflection point passed within 50 km of an active National Data Buoy Center (NDBC) ocean buoy, which provides near-surface (10-m referenced) wind information (Gleason 2013).
The last one is a generalization to all the roughness parameters of the relation identified by Sandoz [18] between the specular gloss (G) and the roughness parameter [R.sub.q]:
Specular viewing of endothelium helps in better selection of corneas.
Specular reflection is generally more polarized than diffuse reflection.
In our previous study, (28) high correlations were attained between visually assessed specular gloss, DOI, and OP, and their instrumentally measured equivalents.
We use an Adaboost method for eye detection and analyze the relation between the pupil center and three specular reflections generated by three IR-LEDs for extracting facial features.
