Latest Patents

Darui Li holds a patent titled "Robust large-scale visual codebook construction." This patent describes techniques for constructing a visual codebook by extracting feature points from a large number of images. In one example, images providing N feature points are utilized to create a codebook of K words. The process involves initializing the centers of K clusters of feature points and iteratively assigning each feature point to a cluster. The assignment is based on the lesser distance to a center of a previously assigned cluster or a center derived from an approximate nearest neighbor algorithm. The loop continues until the feature points converge to their respective clusters, with the centers representing visual words used to construct the visual codebook.
