  • Patent number: 10755397
    Abstract: Systems, computer-implemented methods, and computer program products to focus a microscope. A system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise an analyzer component that can analyze sub-images of respective sample images to identify one or more sub-images having a maximized variance of a gradient derivative corresponding to the one or more sub-images. The respective sample images can be acquired at one or more focal positions along an optical axis of a microscope. The computer executable components can further comprise a selection component that can select an image, from the respective sample images, that comprises the one or more sub-images identified. The computer executable components can also comprise a focus component that, based on a focal position corresponding to the image selected, can focus the microscope to the focal position.

  • Patent number: 10755404
    Abstract: Techniques that facilitate integrated circuit defect detection using pattern images are provided. In one example, a system generates an equalized pattern image of a pattern image associated with a module under test based on an adaptive contrast equalization technique. The system also identifies a first set of features of the equalized pattern image based on a feature point detection technique and aligns the equalized pattern image with a reference pattern image based on the first set of features and a second set of features of the reference pattern image. Furthermore, the system compares a first set of light intensities of the equalized pattern image to a second set of light intensities of the reference pattern image to identify one or more regions of the module under test that satisfy a defined criterion associated with a defect for the module under test.

  • Publication number: 20190191182
    Abstract: A computer-implemented method for finding objects in a collection of images or video, the method comprising: assessing a similarity between two subgraphs; detecting the objects in the collection; assessing a relationship between the objects; finding attributes of the objects; constructing a collection graph for the collection where each of the objects is the vertices and nodes of the collection graph and their relationships with other objects and attributes are edges of the collection graphs; recursively identifying coherent subgraphs and turning the coherent subgraphs into new meta-nodes of the collection graph; identification of the stable graph reducing the collection graph into zero or more distinct stories; assigning a similarity score for each pair of the stories based on a similarity between the corresponding stories; linking the stories into inlier stories based on the similarity score being greater than a first pre-determined threshold level.
