How are motion vectors calculated
Did you know?
WebThe net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out. At this point, the rules for summing vectors (such as force vectors ... Web21 de fev. de 2024 · The motion vector representation is finally learning by using a two-stream CNN. As discussed in above sections, the motion vectors have already been calculated and saved in video stream, which will introduce no extra computation. The proposed method can achieve extremely fast processing speed.
