  • Patent number: 11983853
    Abstract: Systems and methods for generating training data using synthesized input images for training a machine learning model for image enhancement in accordance with embodiments of the invention are described. The system may access a target image (e.g., captured by an imaging device), and generate an input image that corresponds to the target image. The input image and target image may then be used (e.g., as part of a training data set) to train the machine learning model. For example, a generated input image corresponding to a target image may represent a version of the target image as if it were captured in low light. The target image may be a target illuminated output to be generated by enhancing the input image. The input image and target image may be used to train a machine learning model to enhance images such as those captured in low light.

  • Publication number: 20240144537
    Abstract: Embodiments of this application provide a data processing method and system, and an electronic device. The method includes: Before an encoder encodes an image rendered by a graphics processing unit, the graphics processing unit obtains rendering information related to rendered image, compresses the rendering information, and transmits compressed rendering information. Then the encoder may perform encoding optimization based on the compressed rendering information in a process of encoding the rendered image. In this way, a data amount of the rendering information can be reduced, and a transmission delay of the rendering information can be reduced. In addition, the encoder performs encoding after receiving the rendering information. Therefore, in this embodiment of this application, duration of waiting for encoding by the encoder can be reduced, thereby reducing a transmission delay in an entire cloud rendering process.
