Boundary temperature reconstruction in an inverse heat conduction problem using boundary integral equation method
In this paper, we consider an inverse boundary value problem for two-dimensional heat equation in an annular domain. This problem consists of determining the temperature on the interior boundary curve from the Cauchy data (boundary temperature and heat flux) on the exterior boundary curve. To this end, the boundary integral equation method is used. Since the resulting system of linea...

Curve reconstruction algorithms are supposed to reconstruct curves from point samples. Recent papers present algorithms that come with a guarantee: Given a sufficiently dense sample of a closed smooth curve, the algorithms construct the correct polygonal reconstruction. Nothing is claimed about the output of the algorithms, if the input is not a dense sample of a closed smooth curve, e.g., a sa...
متن کاملCurve Reconstruction in Riemannian Manifolds: Ordering Motion Frames
In this article we extend the computational geometric curve reconstruction approach to curves in Riemannian manifolds. We prove that the minimal spanning tree, given a sufficiently dense sample set of a curve, correctly reconstructs the smooth arcs and further closed and simple curves in Riemannian manifolds. The proof is based on the behaviour of the curve segment inside the tubular neighbourh...
متن کاملCurve Reconstruction in Arbitrary Dimension and the Traveling Salesman Problem
Abstract. Given a nite set of points sampled from a curve, we want to reconstruct the ordering of the points along the curve. Every ordering of the sample points can be de ned by a polygon through these points. We show that for simple, regular curves Traveling Salesman Paths give the correct polygonal reconstruction, provided the points are sampled densely enough. In this case the polygonal rec...
متن کاملCraniofacial Reconstruction Using Rational Cubic Ball Curves
This paper proposes the reconstruction of craniofacial fracture using rational cubic Ball curve. The idea of choosing Ball curve is based on its robustness of computing efficiency over Bezier curve. The main steps are conversion of Digital Imaging and Communications in Medicine (Dicom) images to binary images, boundary extraction and corner point detection, Ball curve fitting with genetic algor...
متن کاملOptimized stereo reconstruction of free-form space curves based on a nonuniform rational B-spline model.
Analytical reconstruction of 3D curves from their stereo images is an important issue in computer vision. We present an optimization framework for such a problem based on a nonuniform rational B-spline (NURBS) curve model that converts reconstruction of a 3D curve into reconstruction of control points and weights of a NURBS representation of the curve, accordingly bypassing the error-prone poin...
