Two new research papers introduce novel approaches to cross-modal gait recognition, aiming to improve the identification of individuals across different sensing modalities like 2D cameras and 3D LiDAR. DiffCrossGait utilizes latent diffusion models to align gait trajectories at a fundamental level, rather than just final embeddings, promoting modality-invariant features. TCFDNet employs text-guided feature disentanglement, using large language models to generate semantic descriptions of gait patterns and align visual and textual features for more robust recognition.
