Self-attention outperforms graph convolution for 3D hand pose lifting

By PulseAugur Editorial · [1 sources] ·

Researchers have re-evaluated the use of graph convolutional networks (GCNs) for 2D-to-3D hand pose estimation, finding that standard multi-head self-attention models perform better. Through controlled experiments on the FPHA benchmark, self-attention reduced the mean per-joint position error (MPJPE) from 12.36 mm to 10.09 mm compared to GCNs. The study suggests that adaptive spatial attention is a more effective approach than fixed graph convolution for this task, with hand topology being most beneficial when incorporated as a soft structural prior.

    Rethinking Graph Convolution for 2D-to-3D Hand Pose Lifting

    Graph convolutional networks (GCNs) are widely used for 3D hand pose estimation, where the hand skeleton is encoded as a fixed adjacency graph. We revisit whether this is the most effective way to incorporate hand topology in 2D-to-3D lifting. In this paper, we perform controlled…
