  • Methods and devices for joint sensor and pixel domain denoising
    Patent number: 11967047
    Abstract: A method, apparatus, and a non-transitory computer-readable storage medium for image denoising. The method may include obtaining a raw image captured by a camera. The method may also include obtaining a color modeled image based on the raw image. The method may further include obtaining a subsampled raw image based on the raw image. The method may also include obtaining a denoised image based on a neural network processing the color modeled image and the subsampled raw image.
    Type: Grant
    Filed: September 30, 2021
    Date of Patent: April 23, 2024
    Assignee: KWAI INC.
    Inventors: Paras Maharjan, Ning Xu, Xuan Xu, Yuyan Song

  • METHODS AND DEVICES FOR IMAGE RESTORATION USING SUB-BAND SPECIFIC TRANSFORM DOMAIN LEARNING
    Publication number: 20230099539
    Abstract: A method, apparatus, and a non-transitory computer-readable storage medium for sub-band image reconstruction. The method may include obtaining an image captured by a camera. The method may also obtain a transform image based on the image captured by the camera. The transform image may be in a transform domain. The method may further obtain decomposed image components of the transform image. The decomposed image components may include a low frequency component and at least one high frequency component.
