Identity-Aware Hand Mesh Estimation and Personalization from RGB Images
This addresses the problem of more accurate hand tracking for AR/VR applications, though it is incremental by adding identity awareness to existing methods.
The paper tackles 3D hand mesh reconstruction from monocular RGB images by incorporating identity information, showing improved accuracy over anonymous methods, with state-of-the-art performance validated on two large-scale datasets.
Reconstructing 3D hand meshes from monocular RGB images has attracted increasing amount of attention due to its enormous potential applications in the field of AR/VR. Most state-of-the-art methods attempt to tackle this task in an anonymous manner. Specifically, the identity of the subject is ignored even though it is practically available in real applications where the user is unchanged in a continuous recording session. In this paper, we propose an identity-aware hand mesh estimation model, which can incorporate the identity information represented by the intrinsic shape parameters of the subject. We demonstrate the importance of the identity information by comparing the proposed identity-aware model to a baseline which treats subject anonymously. Furthermore, to handle the use case where the test subject is unseen, we propose a novel personalization pipeline to calibrate the intrinsic shape parameters using only a few unlabeled RGB images of the subject. Experiments on two large scale public datasets validate the state-of-the-art performance of our proposed method.
