In flow visualization, vortex extraction is a long-standing and unsolved problem. For decades, scientists developed numerous definitions that characterize vortex regions and their corelines in different ways, but none emerged as ultimate solution. One reason is that almost all techniques have a fundamental weakness: they are not invariant under changes of the reference frame, i.e., they are not objective. This has two severe implications: First, the result depends on the movement of the… Expand
The State of the Art in Vortex Extraction
TLDR
An overview over the advances that have been made in the analysis of vortices in the last 40 years is provided, providing sufficient background on differential vector field calculus, extraction techniques like critical point search and the parallel vectors operator, and the notion of reference frame invariance is introduced.

Objective Vortex Corelines of Finite-sized Objects in Fluid Flows
TLDR
It is demonstrated in this paper that the objective detection of an inertial vortex coreline can be reduced in 2D to a critical point search in2D and in a number of 2D and 3D vector fields. Expand
Vector Field Topology of Time-Dependent Flows in a Steady Reference Frame
TLDR
This work builds up on recent work on vortex extraction to define a time-dependent vector field topology for 2D and 3D flows and compares and discusses the relationships with existing local and integration-based topology extraction methods, showing for instance that separatrices seeded from saddles in the optimal frame align with the Integration-based streakline vector fieldTopology.

Objective Observer-Relative Flow Visualization in Curved Spaces for Unsteady 2D Geophysical Flows
TLDR
This work develops a general mathematical framework for the objective computation of observer fields for curved spaces, relative to which other computed measures become objective, and develops the case of unsteady 2D geophysical flows given on spheres, such as the Earth. Expand
Time-Dependent Flow seen through Approximate Observer Killing Fields
TLDR
This work compute a time-dependent observer velocity field that describes the motion of a continuous field of observers adapted to the input flow, corresponding to almost-rigid motion, and proves that theinput flow perceived by the observer field is objective, which makes derived flow features, such as vortices, objective as well.

TLDR
Finite-sized particles are introduced as new application area for flow visualization, covering geometry-based methods, particle separation, topology, vortex corelines, and the determination of the origin of finite- sized particles. Expand
Vortex criteria can be objectivized by unsteadiness minimization
Reference frame optimization is a generic framework to calculate a spatially-varying observer field that views an unsteady fluid flow in a reference frame that is as-steady-as-possible. In thisExpand
Vectorizing Quantum Turbulence Vortex-Core Lines for Real-Time Visualization
TLDR
A novel graph-based data structure is proposed, with iterative graph reduction and density-guided local optimization, to locate sub-grid-scale vortex-core line samples more precisely, which are then vectorized by continuous curves, enabling real-time visualization of high-resolution quantum turbulence structure.

Abstract Several procedures have been proposed to modify non-objective (observer-dependent) local vortex criteria so that they become objective. These modifications are only justifiable if they areExpand
