What is 2D motion field?

In 2D, we will be looking at the projections of those 3D vectors in the image. There will be a 2D flow vector at each point in the image. This is the 2D motion flow field.

What is 2D motion estimation?

Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another; usually from adjacent frames in a video sequence.

Is optical flow same as motion field?

Generally, optical flow corresponds to the motion field, but not always. For example, the motion field and optical flow of a rotating barber's pole are different, as illustrated in figure 3. In general, such cases are unusual, and for this lecture we will assume that optical flow corresponds to the motion field.

What is motion field in computer vision?

Motion in computer vision is a sub-field within computer vision dealing with estimation and analysis of information related to motion in image sequences or in the scene depicted by a camera. Common problems in this field relate to. Estimating the motion field in an image sequence.
