Just as optical flow is the two-dimensional motion of points in an image, scene flow is the three-dimensional motion of points in the world. The fundamental difficulty with optical flow is that only the normal flow can be computed directly from the image measurements, without some form of smoothing or regularization.

Proceedings of the Seventh IEEE International Conference on Computer Vision, 1999
Scene flow is the three-dimensional motion field of points in the world, just as optical flow is the two-dimensional motion field of points in an image. Any optical flow is simply the projection of the scene flow onto the image plane of a camera. We present a framework for the computation of dense, non-rigid scene flow from optical flow.

Three-dimensional flow separation
Sadhana, 1993Separation of three-dimensional flow, although much more common than its two-dimensional counterpart, has defied precise description and definition in spite of numerous attempts. Here, we briefly review the grammar that is used to describe various facets of the phenomenon, and use some recent numerical and experimental results to illustrate the ...

Three‐dimensional flow‐independent peripheral angiography
Magnetic Resonance in Medicine, 1997AbstractA magnetization‐prepared sequence, T2‐Prep‐IR, exploits T1, T2, and chemical shift differences to suppress background tissues relative to arterial blood. The resulting flow‐independent angiograms depict vessels with any orientation and flow velocity. No extrinsic contrast agent is required. Muscle is the dciminant source of background signal in

Modeling Three-Dimensional Flow
1987The basic laws governing the flow of water were presented in the previous chapter. However, one cannot solve flow problems by using only these laws. Equation (2.1.19) is a single equation in two dependent variables: q(x, y, z, t) and o(x, y, z, t). It can also be regarded as three equations in four unknowns o, q x , q y ,q z .

Computing three‐dimensional free surface flows
International Journal for Numerical Methods in Engineering, 1976AbstractFinite element techniques are developed for the analysis of high‐speed three‐dimensional free surface flows within the context of potential flow theory. The primary dependent variable is the velocity potential, which is approximated as a quadratic within each isoparametric element.
