  • Publication number: 20240412457
    Abstract: A model establishment method and a related apparatus are provided. The method includes: obtaining projected coordinates of N vertices that are in an original model and that are projected on a target plane; determining M vertices from the N vertices, wherein m is a positive integer greater than or equal to 3 and less than or equal to N; and establishing, based on projected coordinates of the M vertices and height information of the original model, a proxy model corresponding to the original model. According to the application, the proxy model of the original model may be established. The proxy model retains details of the original model, but includes fewer vertices, which simplifies a structure.

  • Publication number: 20220076074
    Abstract: In embodiments of the present disclosure, a method, device and computer-readable medium for multi-source domain adaptation are provided. The method comprises generating a first representation of a target image through a first trained classifier, generating a second representation of the target image through a second trained classifier, and generating a third representation of the target image through a third trained classifier. A mutual learning is conducted among the first, second and third classifiers during the training. The method further comprises determining a classification label of the target image based on the first, second and third representations. The present disclosure proposes a mutual learning network for multi-source domain adaptation, which can improve the accuracy of label generation for images.
