GaMi: Geometry-Agnostic Material Identification via Cross-Modal Subtractive Disentanglement
GaMi is a multimodal material identification system that uses mmWave and acoustic sensing with a cross-modal subtractive disentanglement framework to achieve high accuracy (95.2%) for material identification regardless of geometric variations.
