These algorithms estimate the amount of motion on a block by block basis, ie for each block in the current frame, a block from the previous frame is found.
2D motion vector field: the 2D motion vector field is defined as the projection of the 3D objects motion onto the 2D image plane.
We show that rotation is uniquely determined if and only if it is around the optical axis. In Section IV, we reexamine Huang and Lee's three-view algorithm and ...
