  • Publication number: 20220092334
    Abstract: Feature descriptor matching is reformulated into a graph-matching problem. Keypoints from a query image and a reference image are initially matched and filtered based on the match. For a given keypoint, a feature graph is constructed based on neighboring keypoints surrounding the given keypoint. The feature graph is compared to a corresponding feature graph of a reference image for the matched keypoint. Relocalization data is obtained based on the comparison.

  • Patent number: 11281993
    Abstract: Systems and processes for metric learning distillation are disclosed herein. In accordance with one example, a method includes, at an electronic device, at an electronic device having one or more processors and memory, receiving a first plurality of vectors from a first model, receiving a second plurality of vectors from a second model, determining a first plurality of vector distances based on the first plurality of vectors, generating a first matrix based on the first plurality of vector distances, determining a second plurality of vector distances based on the second plurality of vectors, generating a second matrix based on the second plurality of vector distances, comparing the first matrix with the second matrix, and adjusting the second model based on the comparison of the first matrix and the second matrix.

  • Patent number: 11163981
    Abstract: A facial recognition authentication process operating on a device may capture an image of a user using a camera on the device. The facial recognition authentication process may include operating a full face facial recognition authentication process on the captured image or operating a partial face facial recognition authentication process on the captured image. The process may determine which process to operate (either full face or partial face) based on an assessment of an amount of occlusion in the captured image. The partial face facial recognition authentication process may be operated when there is at least some occlusion of selected features (e.g., nose and/or mouth) on the user's face in the captured image.

  • Patent number: 9538982
    Abstract: An ultrasound scanning system includes a graphical user interface that provides visually intuitive feedback to a user to assist the user in properly aligning an ultrasound scanner to a desired acquisition state. In addition to providing pose information, the feedback may direct the user as to a target contact force applied by the ultrasound scanner to a surface undergoing a scan.

  • Publication number: 20120172710
    Abstract: A contact force sensor is used to detect an instantaneous contact force for an ultrasound probe while an ultrasound image is obtained. The contact force can be used to evaluate tissue deformation in response to the applied force, which permits enhanced imaging such as estimation of undeformed tissue shapes and a determination of tissue elasticity.
