Latest Patents

Yongmin Li's latest patents include a method and system for estimating global motion in video sequences. This invention focuses on estimating the global motion between frames of a motion-compensated inter-frame encoded video sequence directly from the motion vectors encoded within the frames. For any particular frame, the motion vectors are first decoded, and a finite number of sets of vectors are selected. An affine or other geometrical transform is then used to generate a motion estimation for each set, and the least median squared error present in each motion estimation is calculated. The motion estimation with the smallest least median squared error is then selected as being representative of the global motion in the image of the frame. Additionally, a panoramic image generating method and system utilizes the global motion estimations obtained from this process.

Another patent by Yongmin Li also relates to estimating global motion between frames of a motion-compensated inter-frame encoded video sequence. This invention determines a motion estimation from motion vectors direct from the frame's anchor frame to the frame in question. The motion estimation is checked against pre-determined criteria, and if the criteria are not met, re-estimation along a different route is performed using the bi-directional motion vectors contained within B-frames. This method also describes a panoramic image generating system that makes use of the global motion estimations obtained.
