Abstract: Methods and systems for human gesture recognition and activity detection using augmented data. A computer-implemented method includes receiving motion capture data of a target from a camera, generating a first set of motion trajectories from the motion capture data, generating a first set of augmented motion trajectories using a set of data augmentation functions on the first set of motion trajectories, generating a radar cross-section of the target using the motion capture data to perform at least one of gesture recognition or activity detection, generating one or more synthetic electromagnetic (EM) signatures of one or more activities of the target using the first set of augmented motion trajectories and the radar cross-section, and training a machine learning model configured for EM signature-based gesture recognition or activity detection with a domain adaptation process using the one or more synthetic EM signatures.
