  • Publication number: 20240378860
    Abstract: A feature extraction unit extracts a low-resolution general feature vector of an input image and a high-resolution detailed feature vector of the input image. A general feature distance measurement unit maintains a general weight vector of each class and calculates a general distance vector from the general feature vector and the general weight vector. A detailed feature distance measurement unit maintains a detailed weight vector of each class and calculates a detailed distance vector from the detailed feature vector and the detailed weight vector. A feature distance synthesis unit calculates a synthesized distance vector by synthesizing the general distance vector and the detailed distance vector. A global classification unit determines a class of the input image based on the synthesized distance vector.
