Latest Patents
Among his notable patents, one involves a "Method and system for estimating global motion in video sequences." This invention provides a solution for estimating global motion between frames of motion-compensated, inter-frame encoded video sequences. By decoding motion vectors and selecting sets of vectors, Xu applies geometrical transforms to generate accurate motion estimations, ultimately identifying the most representative global motion through the least median squared error approach. Furthermore, this technique supports the generation of panoramic images using the derived global motion estimations.
Another recent patent focuses on "Video segmentation," a method for segmenting sequences of video images according to scene activity. This approach defines a series of nodes in a multi-dimensional space, applying transformation functions and data clustering algorithms to identify clusters of nodes. By determining representative images from each cluster, the method plots these against elapsed time, revealing scene change activities and allowing for effective segmentation based on the resulting scene density curves.
