arXiv:2605.00242v2 Announce Type: replace-cross Abstract: Millimetre-wave (mmWave) radar offers a more privacy-preserving alternative to RGB-based human pose estimation. However, existing methods typically rely on pre-extracted intermediate representations such as sparse point clouds or spectrogram images, where the rich spatiotemporal information naturally present in radar video streams is discarded for model learning, while such signal processing adds system complexity. In addition, existing solutions are mainly conducted in an end-to-end supervised manner without leveraging unlabelled raw v
The proliferation of AI in computer vision naturally pushes towards developing more privacy-preserving sensing technologies. Advances in mmWave radar processing, combined with self-supervised learning, enable new solutions now.
This development addresses a critical tension between AI-driven monitoring capabilities and privacy concerns, potentially expanding the deployability of human pose estimation in sensitive environments. It suggests a move away from reliance on visual data for certain AI applications.
Human pose estimation can now be achieved with greater privacy and potentially reduced computational complexity by directly processing raw mmWave video streams using self-supervised learning, rather than relying on intermediate representations.
