  • LOCALIZED VISUAL GRAPH FILTERS FOR COMPLEX GRAPH QUERIES
    Publication number: 20240126418
    Abstract: Embodiments of the present invention provide a system for querying a graph based on applying filters to a visual representation of the graph. The system allows complicated graph query operations to be performed with ease visually. During operation, the system obtains data indicating vertices and edges of a graph. The system displays a visual representation of the graph for a user. The system receives, from the user, a command defining a local graph filter comprising a region in the visual representation. The system then filters a representation of the graph, and stores the filtered representation.

  • Method and architecture for AI-assisted supervision for a controlled system
    Patent number: 11960273
    Abstract: Embodiments described herein provide a supervisor for fault management at a production system. During operation, the supervisor can obtain a set of sensor readings and a state of the production system. A respective sensor reading is an output of a sensor in the production system. The supervisor can then determine, using an artificial intelligence (AI) model, whether the set of sensor readings accommodates a fault associated with a corresponding sensor. Subsequently, the supervisor can determine an action that mitigates an effect of the fault and modify the set of sensor readings based on the action. Here, the modified set of sensor readings is used by a controller that controls the production system.

  • Altering pixels to scale images
    Patent number: 11954821
    Abstract: An image has pixels arranged in perpendicular rows/columns. The size of the image is changed to produce a changed-size image and the changed-size image is output. The process of changing the size of the image adds at least one row/column as at least one inserted row/column. The inserted row/column is made up of data from generating adjacent rows/columns of the perpendicular rows/columns. Embodiments that reduce the size of the image remove the generating adjacent rows/columns that were used to form the inserted row/column and, in such reduction processing the inserted row/column is added where the (now removed) generating adjacent rows/columns were previously positioned. In embodiments that increase the size of the image, instead of removing the generating adjacent rows/columns, the inserted row/column is merely inserted between the adjacent rows/columns.

    Abstract: The present disclosure discloses methods and systems for detecting tampering of an infrared (IR) security mark in a document. The method includes receiving the document including the IR security mark, wherein the IR security mark further includes one or more security texts and/or images. The document is scanned to generate scanned data. A portion of the scanned data including the IR security mark is segmented into a plurality of blocks such as blocks of size 32*32. Thereafter, a ratio of white to black pixels is calculated for each block. The calculated ratio is compared with a known threshold for each block. Upon comparison, the IR security mark is detected as a tampered security mark.
