Continuous Matching via Vector Field Flow

Continuous force field analysis for generalized gradient vector flow field

We propose a modification of the generalized gradient vector flow field techniques based on a continuous force field analysis. At every iteration the generalized gradient vector flow method obtains a new, improved vector field. However, the numerical procedure always employs the original image to calculate the gradients used in the source term. The basic idea developed in this paper is to use t...

Flow Surface Probes for Vector Field Visualization

We present a technique called ow surface probes for interactive visualization of 3D steady vector elds. The user places in the ow eld an arbitrarily-shaped seed surface, which is then deformed over time by the local or global 3D vector eld, producing an animation sequence. This sequence and individual frames are used to probe the behavior of the ow eld.

Flow-Induced Inertial Steady Vector Field Topology

Traditionally, vector field visualization is concerned with 2D and 3D flows. Yet, many concepts can be extended to general dynamical systems, including the higher-dimensional problem of modeling the motion of finite-sized objects in fluids. In the steady case, the trajectories of these so-called inertial particles appear as tangent curves of a 4D or 6D vector field. These higher-dimensional flo...
