What is motion vector in image processing?

motion vector: a two-dimensional vector used for inter prediction that provides an offset from the coordinates in the decoded picture to the coordinates in a reference picture.

How do you find the motion vector?

A “motion vector” is calculated by finding a correspondence between rectangles at time t, and rectangles at time t − 1, where t is the frame index in a video signal. Motion vectors were originally invented for video coding.

What are motion vectors used for?

Motion vectors are typically used to compress video by storing the changes to an image from one frame to the next. We use these vectors creatively to detect and track motion and to find an alternative to traditional video decoding using phase shifting.
