    An image processing method includes: determining a current orientation of a target object; judging whether the current orientation satisfies a set condition; if satisfied, controlling a display screen of the device to display a prompt message to prompt the object to adjust the current orientation to not satisfy the condition; if not satisfied, adjusting a display parameter of a viewing frame to indicate that photographing is allowed; loading the target virtual image to a region where the viewing frame is located, in response to a photographing button being triggered, to acquire a target image after a portion of the object in the viewing frame has been replaced by a target virtual image. A photographer can therefore be guided by the current orientation to photograph correctly, thereby improving photographing quality and experience.
    US11250263B2 Gaze-driven augmented reality
    Augmented reality (AR) systems, methods, and instrumentalities are disclosed. A user's gaze point may be estimated and may be used to search for and present information, e.g., information relating to areas on which the user is focusing. The user's gaze point may be used to facilitate or enable modes of interactivity and/or user interfaces that may be controlled by the direction of view of the user. Biometric techniques may be used to estimate an emotional state of the user. This estimated emotional state may be used to be the information that is presented to the user.
    US11250260B2 Automated process for dynamic material classification in remotely sensed imagery
    An automated system is provided for classifying materials in remotely-sensed imagery based on automated construction of a dynamic classifier—namely, a classifier that is automatically trained on the same image to which it is then subsequently applied. A first automated process identifies high confidence exemplars of each class using tailored classification techniques. This data is then used to train a supervised classification model (e.g., discriminant analysis), and the resultant classifier is applied to other pixels in the image that are unclassified or uncertain. Dynamic classification is automatically customized to the current image and can yield a more accurate and efficient material classification versus a static (image-independent) or manually trained classifier. It can overcome various confounding factors including inconsistencies in radiometric calibration, atmospheric conditions, and atmospheric distortions of ground spectra; different viewing and illumination geometries; and regional variations in the composition of certain materials like asphalt and concrete.
