We examine the information available from the motion of specularities (highlights) due to known movements by the viewer. In particular two new results are presented. Firstly, we show for local viewer movements the concave/convex surface ambiguity can be resolved without knowledge of the light source position. Secondly, we investigate what further geometrical information is obtained under extended viewer movements, from tracked motion of a specularity. We show the reflecting surface is… CONTINUE READING
