 Applications
Using Photometric Stereo (PS)
Resolve and suppress albedo
One useful property of photometric stereo is that it implicitly separates
the component of the image due to surface topography from the
component due to surface colouring, i.e it can break camouflage
(see below). This
property makes photometric stereo extremely useful in several applications.
  
Classical texture analysis makes no
distiction between the visual texture of a surface that is due
to surface markings
(albedo) and that due to the roughness of the surface (topographical).
The example below illustrates the difference between these phenomena
and their interaction.
An image texture may be due to a combinnation of surface albedo (right)
and surface shape (left).
