  • Publication number: 20250061547
    Abstract: The present disclosure provides a method and a device for image quality enhancement based on a super-resolution neural network. The present disclosure in at least one embodiment provides an image quality enhancement method optimized for distortion characteristics of a target image, including generating one or more training datasets with one or more distortions, obtaining training distortion characteristic values respectively by inputting the one or more training datasets into a degradation encoder neural network (DEN), obtaining a service distortion characteristic value by inputting a service dataset comprising image patches of the target image into the degradation encoder neural network, computing a similarity between each of the training distortion characteristic values and the service distortion characteristic value, and selecting the training dataset having the highest similarity to the service distortion characteristic value.

  • Patent number: 12096037
    Abstract: Disclosed herein is a method for decoding a video including determining a coding unit to be decoded by block partitioning, decoding prediction syntaxes for the coding unit, the prediction syntaxes including a skip flag indicating whether the coding unit is encoded in a skip mode, after the decoding of the prediction syntaxes, decoding transform syntaxes including a transformation/quantization skip flag and a coding unit cbf, wherein the transformation/quantization skip flag indicates whether inverse transformation, inverse quantization, and at least part of in-loop filterings are skipped, and the coding unit cbf indicates whether all coefficients in a luma block and two chroma blocks constituting the coding unit are zero, and reconstructing the coding unit based on the prediction syntaxes and the transform syntaxes.
