Vector Field Tomography
Computerized tomography usually deals with the determination of scalar quantities from integral information along lines. During the 90's tomographic methods have been developed that enable (at least partial) recovery also of vector elds from integral information. Depending on which component of the vector eld is considered, e.g. the ones parallel or transversal to the line, diierent characteris...
متن کاملExponential Vector Field Tomography
Department of Mathematics, Lund Institute of Technology P.O. Box 118, S-221 00 LUND, Sweden email:[email protected] Abstract. In the exponential Radon transform in R2 , the integrals of a scalar function f over lines, with exponential weight functions, are determined. In this paper we demonstrate how to define two different kinds of exponential Radon transforms for vector fields in R2 in a natu...
متن کاملUncertain 2D Vector Field Topology
We introduce an approach to visualize stationary 2D vector fields with global uncertainty obtained by considering the transport of local uncertainty in the flow. For this, we extend the concept of vector field topology to uncertain vector fields by considering the vector field as a density distribution function. By generalizing the concepts of stream lines and critical points we obtain a number...
متن کاملCombinatorial 2D Vector Field Topology Extraction and Simplification
This paper investigates a combinatorial approach to vector field topology. The theoretical basis is given by Robin Forman’s work on a combinatorial Morse theory for dynamical systems defined on general simplicial complexes. We formulate Forman’s theory in a graph theoretic setting and provide a simple algorithm for the construction and topological simplification of combinatorial vector fields o...
متن کاملDirect algebraic reconstruction and optimal sampling in vector field tomography
2 Sets S (bold line) and translations (dashed line) on the reciprocal lattice of the sampling scheme, i.e., S+2W ?t S k (left, W S is the standard sampling matrix) and S + 2W ?t I k (right, W I is the interlaced sampling matrix). Sampling the Radon transform with a rectangular scheme leads to a lattice in the Fourier space generated by ~ u 1 ; ~ u 2 (see left) for satisfying the non-overlapping...
