Geometry of Isophote Curves

Download www.liv.ac.uk

We consider the intensity surface of a 2D image, we study the evolution of the symmetry sets (and medial axes) of 1-parameter families of iso-intensity curves. This extends the investigation done on 1-parameter families of smooth plane curves (Bruce and Giblin, Giblin and Kimia, etc.) to the general case when the family of curves includes a singular member, as will happen if the curves are obtained by taking plane sections of a smooth surface, at the moment when the plane becomes tangent to the surface. Keywords and Phrases: Isophote curve, symmetry set, medial axis, skeleton, vertex, inﬂexion, shape analysis.
