The complex flow field of curved channels implies the use of a 3D numerical model. For this purpose SSIIM-3D was applied. The collected measured data of the velocity field was used to verify the results of the numerical simulation. To investigate the areas, which are not reliably covered by...
In this paper, we propose a novel unified approach which reasons jointly about 3D scene flow as well as the pose, shape and motion of vehicles in the scene. Towards this goal, we incorporate a deformable CAD model into a slanted-plane conditional random field for scene flow estimation and ...

(or more) time steps, and delivers depth and 3D motion densely for every pixel. Hence, it can be seen as a generalization of optical flow to 3D, or alternatively as stereo for dynamic scenes. Like these two classical problems, scene flow estimation is ill-posed due to the 3D equivalent ...
Flow visualization technologies such as particle tracking velocimetry are broadly used for studying three-dimensional turbulent flow in natural and industrial processes. Despite the advances in three-dimensional acquisition techniques, it is challenging to develop motion estimation algorithms in particle trackin...
Explicit expressions of the 3D velocity field in terms of the conserved quantities of ideal fluid thermocline theory, namely the Bernoulli function, density, and potential vorticity, are generalised in this paper to a compressible ocean with a realistic nonlinear equation of state. The most general ...
