Latest Patents

One of Chunhui Cui's latest patents is titled "Scale changing detection and scaling ratio determination by using motion information." This invention discloses a method for object tracking, which includes determining an area scaling ratio of an object in a video image sequence. In one embodiment, a centroid of the object is determined. One or more directed straight lines are selected, each passing through the centroid and extending from an end of the object's boundary to the opposite end, with an upward direction. A length scaling ratio for each directed straight line is determined by calculating a motion vector for each selected pixel on the line and estimating a change in the line's length based on these vectors.

Another significant patent is "Boundary-based high resolution depth mapping." This invention provides systems and methods for generating high-resolution depth maps from low-resolution depth information using boundary-based processing techniques. The boundary detection algorithms implemented in this invention detect object boundaries, where low-resolution depth samples are typically inaccurate. Boundary-based interpolation algorithms refine intermediate upsampled depth information, resulting in high-resolution depth information.
