What is motion vector?

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 is index and motion vector?

Motion vectors are created by objects moving in the field, someone walking by, cars driving, anything that moves. graphic vectors (GV), weakest. Graphic vectors are created by stationary elements—for instance horizon lines in the background, placement of furniture, etc. index vectors (IV), widest weak-strong range.

What is motion vector difference?

MMVD provides a compromised solution for the tradeoff between motion vector accuracy and its overhead. MMVD can improve motion vector accuracy by introducing a simplified motion vector representation. The results show that the proposed method improves coding efficiency ofV VC with an average of 0.51% in BD-rate saving.
