A method for comparing three-dimensional vector fields constructed from simple critical points is described. This method is a natural extension of previous work (Y. Lavin et al., 1998), which defined a distance metric for comparing two-dimensional fields. The extension to three-dimensions follows the path of our previous work, rethinking the representation of a critical point signature and the distance measure between the points. Since the method relies on topologically based information…

Using Feature Flow Fields for Topological Comparison of Vector Fields
TLDR
A new topology based metric for 2D vector fields based on the concept of feature flow fields is proposed that incorporates both the characteristics and the local distribution of the critical points while keeping the computing time reasonably small even for topologically complex vector fields.
Image Matching Using Dimensionally Reduced Embedded Earth Mover's Distance
TLDR
This work aimed to reduce the execution time of embedded EMD and increase its performance using three dimension reduction methods: sampling, sketching, and Dimension Reduction in Embedding by Adjustment in Tail (DREAT).
Topology-based methods for quantitative comparisons of vector fields
TLDR
This paper provides comparison methods that are based on the topology of the vector field that can be used for both 2D and 3D fields, and depending upon the complexity of the field, different levels of comparisons can be utilized to reduce search times.
Topology preserving compression of 2D vector fields

An advanced and complete classification of all first order critical points of 2D vector fields is given, which forms the foundation of the definition of vector field metrics.
Feature-based Vector Field Representation and Comparison
TLDR
This thesis replaces the visual processing of data in the traditional workflow with an automated, statistical method that enables a quantitative analysis and describes the input data and demonstrates the advantages of the developed representation and its use for the analysis of vector fields using flow graphs.
Topology Preserving Top-Down Compression of 2D Vector Fields Using Bintree and Triangular Quadtrees
TLDR
