  • Publication number: 20110096169
    Abstract: Provided are a camera tracking system and method and a live video compositing system using the same, which track a main camera with a sub-camera attached to the main camera and thus stably calculate the motion of the main camera even in a dynamic case where most of a static background is occluded by a moving foreground object. The camera tracking system and the live video compositing system can connect feature point tracks that are cut by a foreground object which dynamically moves in an image. Accordingly, the camera tracking system and the live video compositing system can perform the more accurate and quick tracking of a camera even in a case where a foreground object occludes background by dynamically moving.

  • Publication number: 20100158353
    Abstract: A method for restoration of building structure using infinity homographies calculated based on parallelograms includes: calculating, using two or more parallelograms, an infinity homography between those cameras which refer to an arbitrary camera; restoring cameras and the building structure on an affine space using the computed infinity homography and homologous points between images; and transforming the restored result onto the metric space using constraints on orthogonality of vectors joining the restored three-dimensional points, the ratio of lengths of the vectors and intrinsic camera parameters. As a result, intrinsic camera parameters, camera positions on the metric space and the structure of the building are restored. All the restoration is possible even when intrinsic camera parameters corresponding to all the images are not constant.

  • Publication number: 20070281477
    Abstract: A method of plasma etching tungsten silicide over polysilicon particularly useful in fabricating flash memory having both a densely packed area and an open (iso) area requiring a long over etch due to microloading. Wafer biasing is decreased in the over etch. The principal etchant include NF3 and Cl2. Argon is added to prevent undercutting at the dense/iso interface. Oxygen and nitrogen oxidize any exposed silicon to increase etch selectivity and straightens the etch profile. SiCl4 may be added for additional selectivity.
