With an impressive portfolio containing 12 patents, Morrison has focused primarily on advancements in motion estimation within video sequences, bringing innovative solutions to the industry.
Latest Patents
Among his latest patents is a groundbreaking method and system for estimating global motion in video sequences. This invention provides a way to estimate global motion between frames of a motion-compensated inter-frame encoded video sequence directly from the motion vectors encoded within the frames. The process involves decoding the motion vectors for any given frame, selecting a finite number of sets of vectors, and applying an affine or other geometrical transform to generate motion estimations. By calculating the least median squared error for each estimation, the motion estimation with the smallest error is identified as representative of the global motion in the frame's image. Additionally, his innovative approach contributes to a method and system for generating panoramic images using the global motion estimations obtained.
Another similar patent complements the first by focusing on estimating global motion between frames through thorough checks against predetermined criteria and re-estimations when necessary. This dual approach enhances the reliability and accuracy of motion estimation in video technology.
