3D hand-mesh reconstruction from RGB images facilitates many applications, including augmented reality (AR).

However, this requires not only real-time speed and accurate hand pose and shape but also plausible mesh-image alignment.

... decoupling the hand-mesh reconstruction task into three stages:

a joint stage to predict hand joints and segmentation;

a mesh stage to predict a rough hand mesh; and

a refine stage to fine-tune it with an offset mesh for mesh-image alignment.

... can promote high-quality finger-level mesh-image alignment and drive the models together to deliver real-time predictions.

... outperforms the state-of-the-art methods on hand-mesh/pose precision and hand-image alignment. ...
