  • Publication number: 20250131468
    Abstract: The technology disclosed herein relates to utilizing a performance anomaly detection model to identify performance metrics (e.g., cost-per-click data) that are above an anomaly threshold. For example, communication sessions can be established with one or more servers hosted by one or more third-parties for receiving performance metrics for a first entity. The performance metrics received for the first entity can be used by the performance anomaly detection model, which can be trained using historical performance metrics (e.g., of the first entity, of the first entity during particular time periods, of the first entity for particular geographical locations), for anomaly detection. Based on one or more anomaly detections, one or more notifications or particular displays can be provided to a user device.

  • Patent number: 8605093
    Abstract: A method, system, apparatus, article of manufacture, and computer readable storage medium provide the ability to reconstruct a pipe from point cloud data. Point cloud data is obtained. Primitive geometric shapes are detected in the point cloud data. A pipeline is determined by determining predecessor and successor primitive geometric shapes for each of the shapes. Diameters, coplanarity, and angles between the shapes are corrected. The shapes are connected and output.

  • Publication number: 20110304619
    Abstract: A method, apparatus, system, article of manufacture, and data structure provide the ability to extract a primitive quadric surface from point cloud data. Point cloud data is obtained in 3D space. The point cloud data is segmented to create a disjoined surface and a smooth surface segment based on spatial connectivity and surface smoothness. One or more shapes are extracted from the point cloud data using geometric fitting. The geometric fitting searches for one or more quadric surface parameters of a given type of model that provides a best agreement between selected points from the point cloud data and a resultant model.
