  • Systems and methods for anatomy-constrained gaze estimation
    Patent number: 11829523
    Abstract: Anatomically-constrained gaze estimation providing a point of reference (PoR) in a 3D field and/or 2D plane, based on 6 DOF head pose constrained by the eyeball center being fixed in a common 3D coordinate system.
    Type: Grant
    Filed: October 23, 2022
    Date of Patent: November 28, 2023
    Inventors: Gilad Drozdov, Oren Haimovitch-Yogev, Uri Wollner
  • Systems and methods of processing magnetic resonance images using phase-sensitive structural similarity index measure
    Patent number: 11756197
    Abstract: A computer-implemented method of processing complex magnetic resonance (MR) images is provided. The method includes receiving a pair of corrupted complex data and pristine complex images. The method also includes training a neural network model using the pair by inputting the corrupted complex data to the neural network model, setting the pristine complex images as target outputs, and processing the corrupted complex data using the neural network model to derive output complex images of the corrupted complex data. Training a neural network model also includes comparing the output complex images with the target outputs by computing a phase-sensitive structural similarity index measure (PS-SSIM) between each of the output complex images and its corresponding target complex image, wherein the PS-SSIM is real-valued and varies with phases of the output complex image and phases of the target complex image, and adjusting the neural network model based on the comparison.
