    • Systems and methods for characterizing a spatial frequency of interface regions within a subterranean formation. A first method may include drilling a wellbore with a drilling assembly and measuring a downhole parameter during the drilling. The downhole parameter may be indicative of a lithology of a portion of the subterranean formation that is proximal to the drilling assembly. The first method also may include calculating an information entropy of the downhole parameter and characterizing the spatial frequency of the interface regions based upon the information entropy. A second method may include calculating the information entropy as a function of distance within a first wellbore and characterizing the spatial frequency of the interface regions. The second method also may include drilling a second wellbore within the subterranean formation and regulating the drilling based upon the spatial frequency of the interface regions. The systems include systems that perform the methods.
    • 用于表征地层内界面区域的空间频率的系统和方法。 第一种方法可以包括用钻井组件钻井井并在钻井期间测量井下参数。 井下参数可以指示靠近钻井组件的地下地层的一部分的岩性。 第一种方法还可以包括基于信息熵计算井下参数的信息熵和表征接口区域的空间频率。 第二种方法可以包括计算作为第一井筒内的距离的函数的信息熵并表征界面区域的空间频率。 第二种方法还可以包括在地层内钻第二井眼,并且基于界面区域的空间频率来调节钻井。 系统包括执行方法的系统。

    • Embodiments of the disclosure provide for systems and methods for creating metadata associated with a video data. The metadata can include data about objects viewed within a video scene and/or events that occur within the video scene. Some embodiments allow users to search for specific objects and/or events by searching the recorded metadata. In some embodiments, metadata is created by receiving a video frame and developing a background model for the video frame. Foreground object(s) can then be identified in the video frame using the background model. Once these objects are identified they can be classified and/or an event associated with the foreground object may be detected. The event and the classification of the foreground object can then be recorded as metadata.
    • 本公开的实施例提供了用于创建与视频数据相关联的元数据的系统和方法。 元数据可以包括关于在视频场景内观看的对象的数据和/或在视频场景内发生的事件。 一些实施例允许用户通过搜索记录的元数据来搜索特定对象和/或事件。 在一些实施例中,通过接收视频帧并开发视频帧的背景模型来创建元数据。 然后可以使用背景模型在视频帧中识别前景对象。 一旦识别出这些对象,就可以对它们进行分类和/或可以检测与前景对象相关联的事件。 然后可以将事件和前景对象的分类记录为元数据。
