Specular reflections or specularities carry valuable information about the geometry of reflective surfaces and can be used to recover their shape.
Background
Cues such as texture and shading are often inadequate for recovering the shape of shiny reflective objects. For such objects it is not possible to observe their surfaces directly, rather only what they reflect. Yet, specular reflections present an additional cue that potentially may be exploited for shape recovery. A curved mirror produces “distorted” images of the surrounding world. For example, the image of a straight line reflected by a curved mirror is, in general, a curve (Fig. 2). It is clear that such distortions are systematically related to the shape of the surface. Is it possible to invert this map and recover the shape of the mirror from its reflected images? The general “inverse mirror” problem is under-constrained: by opportunely manipulating the surrounding world,...
