    • The present invention is directed to the use of linkcells in retrieving site data pertaining to one or more sites from a site data repository. The linkcells facilitate the resolution of several types of queries, including queries to determine a specified number of closest sites to a user's location and queries to determine sites located with a specified distance of the user's location. In one aspect, the present invention relates to a linkcell having a cell perimeter that comprises one or more cell boundary sections, a cell identifier, and a link to a data table, where one or more sites are associated with the linkcell, and where site data pertaining to those sites is stored in the data table. The cell identifier may be a name derived from the coordinates of sites associated with the linkcell. Advantageously, it is not typically necessary to examine data on all sites in the site data repository to resolve queries if linkcells are used.
    • 本发明涉及链接单元在从站点数据存储库检索与一个或多个站点有关的站点数据时的用途。 链路单元有助于解决几种类型的查询,包括确定到用户位置的指定数量的最近站点的查询,并查询以确定位于用户位置的指定距离的站点。 一方面,本发明涉及一种具有小区周边的链路蜂窝小区,该小区周边包括一个或多个小区边界部分,小区标识符和到数据表的链路,其中一个或多个站点与链路蜂窝小区相关联,并且其中站点 与这些站点相关的数据存储在数据表中。 小区标识符可以是从与链路蜂窝小区相关联的站点的坐标得到的名称。 有利的是,通常不需要检查站点数据存储库中的所有站点上的数据,以便在使用链路单元时解析查询。

    • A system and method implemented as a software tool for generating alpha matte sequences in real-time for the purposes of background or foreground substitution in digital images and video. The system and method is based on a set of modified Poisson equations that are derived for handling multichannel color vectors. Greater robustness is achieved by computing an initial alpha matte in color space. Real-time processing speed is achieved through optimizing the algorithm for parallel processing on the GPUs. For online video matting, a modified background cut algorithm is implemented to separate foreground and background, which guides the automatic trimap generation. Quantitative evaluation on still images shows that the alpha mattes extracted using the present invention has improved accuracy over existing state-of-the-art offline image matting techniques.
    • 实现为用于在数字图像和视频中为背景或前景替换的目的实时生成阿尔法无序序列的软件工具的系统和方法。 该系统和方法基于为处理多通道颜色矢量导出的一组修正泊松方程。 通过计算颜色空间中的初始alpha遮罩来实现更强的鲁棒性。 通过优化GPU上的并行处理算法实现实时处理速度。 对于在线视频消隐,实现了一种改进的背景剪切算法来分离前景和背景,从而引导自动生成细分。 静止图像的定量评估表明,使用本发明提取的阿尔法无光泽比现有的最先进的离线图像消光技术提高了精度。
