Texture Classification by Audio- Tactile Crossmodal Congruence

This work presents a large-scale texture classification method using a novel texture feature Projected Spectral Mapping (PSM) based on audio-tactile crossmodal congruence in unconstrained tool-surface interactions. We describe a quick-computable extraction process for PSM from the proposed crossmodal inter-band spectral mapping (IBSM) that relates the frequency components in different bands betwee...
