Flow vector
WebThis gives the vector (avg_u, avg_v) needed to translate. Regarding your comments , it seems you want to move every pixel (x,y) to the location specified by its flow vector (u(x,y), v(x,y)) . First, generate a Cartesian grid: WebSep 26, 2024 · Optical flow field of two images. Optical flow is a vector field between two images, showing how the pixels of an object in the first image can be moved to form the same object in the second image. It is a kind of correspondence learning, because if the corresponding pixels of an object are known, the optical flow field can be calculated.

In continuum mechanics the flow velocity in fluid dynamics, also macroscopic velocity in statistical mechanics, or drift velocity in electromagnetism, is a vector field used to mathematically describe the motion of a continuum. The length of the flow velocity vector is the flow speed and is a scalar. It is also called velocity field; when evaluated along a line, it is called a velocity profile (as in, e.g., law of the wall). WebNow think about a vector quantity, for example the flow vector that determines the direction of water flow at a certain point in a river. We can assign such a vector to any point in the river at any moment of time. Thus we arrive at a vector field that can be graphically represented by field lines that are tangential to the direction of the ...
