1 results about "Food classification" patented technology

This application relates to the field of smart home appliance technology, and discloses a method and apparatus for cross-domain small-sample object image classification for smart terminals. The method includes: acquiring an image of food to be identified; processing the image to extract basic feature vectors; mapping the basic feature vectors using a dual Riemannian manifold processing module to obtain Euclidean space features and hyperbolic space features respectively; fusing the Euclidean space features and hyperbolic space features to obtain a comprehensive feature representation for food classification; and determining the food classification result based on the comprehensive feature representation. The dual Riemannian manifold processing module includes Euclidean space branches and hyperbolic space branches. This method achieves multi-space feature fusion by collaboratively extracting Euclidean space features and hyperbolic space features using dual Riemannian manifolds, thereby improving the feature representation capability and classification accuracy of food images.
