    • Object tracking systems and methods are described. In one aspect, a three-dimensional point cloud is generated from a time series of video frames and partitioned into a set of vertically-oriented bins. The point cloud is mapped into one or more plan-view images each containing for each vertically-oriented bin a corresponding pixel having one or more values computed based upon one or more attributes of the point cloud members occupying the corresponding vertically-oriented bin. The object is tracked based at least in part upon one or more of the plan-view images. In another aspect, one or more original object templates are extracted from at least one of the one or more plan-view images, and the object is tracked based at least in part upon a comparison of at least one of the object templates with regions of the corresponding plan-view images. In another aspect, the point cloud may be discretized along the vertical axis into two or more horizontal partitions.
    • 描述对象跟踪系统和方法。 在一个方面,从视频帧的时间序列生成三维点云,并将其划分成一组垂直取向的仓。 点云被映射到一个或多个平面图像中,每个图像包含用于每个垂直取向的仓的相应的像素,该对应的像素具有基于占据相应垂直取向仓的点云构件的一个或多个属性计算的一个或多个值。 至少部分地基于一个或多个平面图图像跟踪对象。 在另一方面,从一个或多个平面图像中的至少一个提取一个或多个原始对象模板,并且至少部分地基于至少一个对象模板与 相应的平面图图像。 在另一方面,点云可以沿垂直轴离散成两个或更多个水平分隔。

    • The APPARATUSES, METHODS AND SYSTEMS FOR A VISUAL QUERY BUILDER (“VQB”) take user gesture inputs on displayed objects, and transform them via VQB components into search results display objects arranged by search relevance in proximity to the displayed objects. In one embodiment, the VQB obtains an object-manipulating gesture input, and correlates the object-manipulating gesture input to a display object. The VQB then classifies the object-manipulating gesture input as a specified type of search request. The VQB generates a search query according to the specified type of search request using metadata associated with the display object, and provides the search query to search engine(s) and/or database(s). The VQB obtains, in response to providing the search query, search result display objects and associated search result display object relevance values. The VQB displays the search result display objects arranged in proximity to the display object such that search result display objects are arranged according to their associated search result display object relevance values.
    • 视觉查询建筑物(“VQB”)的设备,方法和系统在显示对象上进行用户手势输入,并通过VQB组件将其转换成搜索结果显示对象,通过搜索相关性排列在显示对象附近。 在一个实施例中,VQB获得对象操纵手势输入,并且将对象操纵手势输入与显示对象相关联。 然后,VQB将对象操纵手势输入分类为指定类型的搜索请求。 VQB使用与显示对象相关联的元数据根据指定类型的搜索请求生成搜索查询,并将搜索查询提供给搜索引擎和/或数据库。 响应于提供搜索查询,VQB获得搜索结果显示对象和相关联的搜索结果显示对象相关性值。 VQB显示布置在显示对象附近的搜索结果显示对象,使得搜索结果显示对象根据其相关联的搜索结果显示对象相关性值被排列。
