  • Patent number: 12277674
    Abstract: A semantics-based high resolution reconstruction method of a nighttime light remote sensing image includes: constructing a sample data set; the sample data set includes a plurality of data groups, and each data group includes a LR NTL image, and a HR NTL image and light semantics information consistent in spatial position with the LR NTL image; constructing a reconstruction model; performing training and validation on the reconstruction model by using the sample data set to obtain an optimized reconstruction model; and taking a to-be-reconstructed LR NTL image and light semantic information corresponding to the to-be-reconstructed LR NTL image as an input of the optimized reconstruction model, and outputting, by the optimized reconstructed model, a HR NTL image obtained through resolution reconstruction.

  • Patent number: 11674007
    Abstract: A modified collagen fiber preparation method and application are provided. The modified collagen fiber is prepared by modifying a collagen fiber with a plant tannin; and a method of the preparation includes: mixing the plant tannin with the collagen fiber in a liquid environment with a pH of 5 to 8 to allow a reaction, and washing and drying a product. In the present disclosure, a plant tannin rich in phenolic hydroxyl can be combined with a collagen fiber in various ways such as multi-point hydrogen bonding and hydrophobic bonding, such that the plant tannin structure is introduced into a natural multi-layer micro/nano-structure of the collagen fiber; and due to a large number of phenolic hydroxyl structures in the plant tannin, the collagen fiber introduced with the plant tannin structure shows improved compatibility with a waterborne resin, and can produce strong hydrogen bonding with polar groups in the waterborne resin.
