  • Publication number: 20240118772
    Abstract: This document describes systems and techniques directed at mitigating display diffraction flares for under-display sensing. In aspects, an equation may be derived that models the effects of a display in producing a diffraction phenomenon at an image plane of a sensing region for an under-display light-sensing device. The equation may be used to determine an arrangement (e.g., an optimized arrangement) of components (e.g., sub-pixels) within the display that minimizes a diffraction efficiency for at least one diffraction order and, thereby, mitigates an intensity and/or a prevalence of optical artifacts in light-sensing data. In implementations, an image intensity point-spread-function is utilized to calculate diffraction efficiencies for respective diffraction orders (e.g., the lowest diffraction orders, the diffraction orders with the greatest brightness).

    Abstract: Presented herein are systems and methods for an end-to-end solution for object removal from a video using adaptive learning. In one or more embodiments, using a pre-trained image inpainting model, in-scene training data may be generated using optical-flow guided sampling. In one or more embodiments, the sampled patches are used to generate a training dataset, which is used to further train the image inpainting model until reaching a stop condition. The adaptively trained inpainting model may be used to generate a modified video in which the desired object or objects have been removed and the corresponding removed portion(s) have been filled (or inpainted) to preserve the integrity of the image.

  • Publication number: 20240088963
    Abstract: Embodiments of this application provide a method and an apparatus for determining radio channel multipath information and a related device. A server obtains reference signal received powers of a plurality of downlink beams, and determines a path angle and path strength of a propagation path from an antenna in a power angular spectrum cell indicated by each power angular spectrum cell identity to a grid indicated by each grid identity, based on an association relationship between the reference signal received powers of the plurality of downlink beams and the following: a grid identity, a serving cell identity, and a power angular spectrum cell. The server can determine the radio channel multipath information based on the reference signal received powers of the plurality of downlink beams, instead of depending on map and engineering parameter information. This helps improve accuracy of the radio channel multipath information.
