FG3DFormer: Fine-Grained 3D Shape Classification Based on Vision Transformer
ICASSP 2025accepted
Fine-grained 3D shape classification (FGSC) remains challenging due to the difficulty of adaptively capturing global structure differences and subtle inter-class distinctions. This paper directly extends Vision Transformer (ViT) to FGSC, proposing a pure Transformer network FG3DFormer that fully lev…
