  • Publication number: 20250054205
    Abstract: The present disclosure relates to a method and system for reconstructing an image of a midpalatal suture based on a Sobel operator and belongs to the technical field of image processing. Firstly, data preprocessing is performed on a cone beam computed tomography (CBCT) file of a midpalatal suture of a maxilla to obtain a plurality of local images of the midpalatal suture. Merging fusion is then performed on the plurality of local images of the midpalatal suture to obtain a reconstructed image of the midpalatal suture, and a Sobel operator is utilized for optimization during the merging fusion. Thus, an overall profile of a region shape of the midpalatal suture can be reconstructed in a same image from midpalatal suture regions distributed in multiple layers of CBCT images, facilitating intuitive and accurate judgment on the midpalatal suture region by a doctor.

  • Patent number: 11250044
    Abstract: Given a skeleton knowledge graph including first terms in respective nodes, wherein first terms in connected nodes have a predetermined relationship, an augmented knowledge graph is formed by a first computing device by extracting a second term from a domain corpus to form a term cluster linked with a respective node of the knowledge graph. The second term is associated with the first term of a respective node in the domain corpus while not meeting the predetermined relationship. A semantic feature between the second term and the associated first term is identified in the domain corpus and linked to the pair of the second term and the first term in the augmented knowledge graph. The augmented knowledge graph is useable by a second computing device, which may or may not be the same as the first computing device, to drive a conversation between a chatbot and user.
