    • Various embodiments provide a set of algorithms and scripts, e.g., SQL scripts, to perform automatic horizontal table and index partitioning that allows overlapping of data records, used in full-text search queries. In at least some embodiments, table creation and populating script is utilized to create a set of smaller tables partitioned by one column. In at least some embodiments, SELECT query modification script is provided to generate a query that works on the partitioned tables to achieve better performance. In at least some other embodiments, other query creation script is provided to modify the INSERT/UPDATE/DELETE queries for the original large table to automatically keep these queries synchronized with partitioned tables.
    • 各种实施例提供一组算法和脚本,例如SQL脚本,以执行允许在全文搜索查询中使用的数据记录的重叠的自动水平表和索引分割。 在至少一些实施例中,使用表创建和填充脚本来创建由一列分割的一组较小的表。 在至少一些实施例中,提供了SELECT查询修改脚本以生成在分区表上工作的查询以实现更好的性能。 在至少一些其他实施例中,提供了其他查询创建脚本来修改原始大表的INSERT / UPDATE / DELETE查询以自动保持这些查询与分区表同步。

    • Apparatus and methods for detecting multiple images in digital image data are described. In one aspect, an edge map is generated from image data. The edge map is analyzed to determine a set of boundaries of the one or more objects by. This analysis is accomplished by: (a) determining a set of transitions between the set of boundaries and a background color; (b) identifying a set of characteristics from the set of transitions, wherein the set of characteristics are used to indicate whether the image data comprises a single object or whether the image data comprises a plurality of objects; and (c) if the image data corresponds to a plurality of objects, assigning particular ones of the set of boundaries to particular ones of the plurality of objects based on a set of rules. The one or more objects are segmented based on the set of boundaries.
    • 描述了用于检测数字图像数据中的多个图像的装置和方法。 在一个方面,从图像数据生成边缘图。 分析边缘图以确定一个或多个对象的一组边界。 该分析是通过以下方式实现的:(a)确定一组边界与背景颜色之间的一组过渡; (b)从所述一组转换中识别一组特征,其中所述特征集用于指示所述图像数据是包括单个对象还是所述图像数据是否包括多个对象; 以及(c)如果所述图像数据对应于多个对象,则基于一组规则将所述一组边界的特定特征分配给所述多个对象中的特定对象。 一个或多个对象基于边界集分割。

    • A technique, specifically apparatus and accompanying methods, which utilizes a trie-indexed hierarchy forest ("rhizome") that accommodates wildcards for retrieving, given a specific input key, a pattern stored in the forest that is identical to or subsumes the key. The rhizome contains a binary search trie and a hierarchy forest. The search trie provides an indexed path to each unique, most specific, pattern stored in a lowest level of the hierarchy forest and also possibly to increasingly general patterns at higher levels in the pattern hierarchy. The hierarchy forest organizes the patterns into nodal hierarchies of strictly increasing generality. For use as a packet classifier, the rhizome stores wildcard-based packet classification patterns at separate corresponding pattern nodes, along with, corresponding "reference" fields associated therewith. Operationally, as each different queue is established or removed, a corresponding classification pattern is either inserted into or removed from the rhizome. A search key is formed for each packet, typically by concatenating classification fields, e.g. source and destination addresses and source and destination port designations, appearing in a header of the packet. The search key is then applied to the rhizome to determine whether that key exists therein, by virtue of either matching an identical classification pattern or being completely subsumed within a more general pattern stored therein. When such a classification is found, the classifier returns the contents of the associated reference field, which for scheduling, is a designation of a transmission queue to which the packet is to be directed.
    • 一种技术,具体是装置和伴随的方法,其利用特定索引层级林(“根茎”),其适应通配符,以在给定特定输入密钥的情况下检索与森林中存储的模式相同或包含密钥。 根茎含有二分搜索特技和层级森林。 搜索特技提供了存储在层次结构林的最低级别中的每个独特的,最具体的模式的索引路径,并且还可能在模式层次结构中的较高级别的日益普遍的模式。 层次结构林将模式组织成具有严格增加的普遍性的节点等级。 为了用作分组分类器,根茎在单独的相应模式节点上存储基于通配符的分组分类模式,以及与其相关联的相应“参考”字段。 在操作上,随着每个不同的队列被建立或删除,相应的分类模式被插入或从根茎去除。 通常通过连接分类字段来为每个分组形成搜索关键字,例如, 源和目标地址以及出现在数据包标题中的源和目标端口名称。 然后将搜索关键字应用于根茎,以通过匹配相同的分类模式或完全包含在其中存储的更一般的模式中来确定该密钥是否存在于其中。 当发现这样的分类时,分类器返回相关联的参考字段的内容,其用于调度,是分组要被引导到的传输队列的指定。
