Continuous Maps on Digital Simple Closed Curves
We give digital analogues of classical theorems of topology for continuous functions defined on spheres, for digital simple closed curves. In particular, we show the following: 1) A digital simple closed curve S of more than 4 points is not contractible, i.e., its identity map is not nullhomotopic in S ; 2) Let X and Y be digital simple closed curves, each symmetric with respect to the origin, ...
متن کاملPseudo-anosov Maps and Simple Closed Curves on Surfaces
Suppose C and C are two sets of simple closed curves on a hyperbolic surface F . We will give necessary and sufficient conditions for the existence of a pseudo-Anosov map g such that g(C) ∼= C. Pseudo-Anosov maps are the most important class among surface homeomorphisms [Th3], and they play important roles in 3-manifold theory [Th2]. This note is to address the following question: Suppose F is ...
متن کاملOn the Unfolding of Simple Closed Curves
We show that every rectifiable simple closed curve in the plane can be continuously deformed into a convex curve in a motion which preserves arc length and does not decrease the Euclidean distance between any pair of points on the curve. This result is obtained by approximating the curve with polygons and invoking the result of Connelly, Demaine, and Rote that such a motion exists for polygons....
متن کاملConcerning Simple Continuous Curves
Various definitions of simple continuous arcs and closed curves have been given, f The definitions of arcs usually contain the requirement that the point-set in question should be bounded. In attempting to prove that every interval t of an open curve as defined in a recent paper \ is a simple continuous arc, while I found it easy to prove that t satisfies all the other requirements of Janiszews...
متن کاملParticle Filtering for Continuous Closed Curves
We propose a particle filtering algorithm for tracking continuous closed curves which form the boundary of objects in images. This can be used for tracking moving and deforming objects from a sequence of images. Particle filtering for continuous curves is difficult since they form an infinite dimensional state space and generating Monte Carlo samples from a very large dimensional (theoretically...
