GaMi: Geometry-Agnostic Material Identification via Cross-Modal Subtractive Disentanglement
GaMi is a multimodal material identification system that combines mmWave and acoustic sensing to accurately identify materials regardless of geometric variations like shape, orientation, and distance. Using cross-modal subtractive disentanglement and contrastive learning, the system achieves 95.2% accuracy on 20 materials and demonstrates few-shot generalization across different devices.
