  • Hierarchical constraint (HC)-based method and system for classifying fine-grained graptolite images
    Patent number: 11804029
    Abstract: The present disclosure relates to a hierarchical constraint (HC) based method and system for classifying fine-grained graptolite images. The method includes: constructing a graptolite fossil dataset; extracting features in graptolite images; calculating the similarity between graptolite images, and performing weighting according to a genetic relationship among species to obtain a weighted HC loss function (HC-Loss) of all graptolite images; calculating cross-entropy loss; taking a weighted sum of HC-Loss and CE-Loss as a total loss function in a training stage; and performing model training. The system of the present disclosure includes a processor and a memory.
    Type: Grant

    Date of Patent: October 31, 2023
    Assignees: Nanjing Institute of Geology and Palaeontology, CAS, Tianjin University
    Inventors: Honghe Xu, Yaohua Pan, Zhibin Niu
