Latest Patents

Zhujiang Cao holds a patent titled "Colon characteristic path registration." This patent discusses systems and methods for efficiently calculating a registration of multiple characteristic paths of a virtual three-dimensional object. Each path of discrete points is transformed into a piecewise linear parameterization as a function of path length. The paths are smoothed and normalized, and the shorter path is partitioned into a number of discrete subintervals. These subintervals are then mapped to the longer path using a minimization function that minimizes a cost function, resulting in a locally optimal registration. The shorter path is incrementally positioned along the longer path, and the minimization is attempted at each position. When the shorter path cannot be shifted any farther, the globally optimal registration is returned. This innovative approach has the potential to significantly improve the accuracy and efficiency of virtual object registration.
