• Abstract summary: HOLD -- the first category-agnostic method that reconstructs an articulated hand and object jointly from a monocular interaction video. We develop a compositional articulated implicit model that can disentangled 3D hand and object from 2D images. Our method does not rely on 3D hand-object annotations while outperforming fully-supervised baselines in both in-the-lab and challenging in-the-wild settings.

• Abstract: Since humans interact with diverse objects every day, the holistic 3D capture of these interactions is important to understand and model human behaviour. However, most existing methods for hand-object reconstruction from RGB either assume pre-scanned object templates or heavily rely on limited 3D hand-object data, restricting their ability to scale and generalize to more unconstrained interaction settings. To this end, we introduce HOLD -- the first category-agnostic method that reconstructs an articulated hand and object jointly from a monocular interaction video. We develop a compositional articulated implicit model that can reconstruct disentangled 3D hand and object from 2D images. We also further incorporate hand-object constraints to improve hand-object poses and consequently the reconstruction quality. Our method does not rely on 3D hand-object annotations while outperforming fully-supervised baselines in both in-the-lab and challenging in-the-wild settings. Moreover, we qualitatively show its robustness in reconstructing from in-the-wild videos. Code: https://github.com/zc-alexfan/hold

  Our work aims to reconstruct hand-object interactions from a single-view image. We first design a novel pipeline to estimate the underlying hand pose and object shape. With the initial reconstruction, we employ a prior-guided optimization scheme.

  Given a monocular RGB video, we aim to reconstruct hand-held object geometry in 3D, over time. We present MCC-Hand-Object (MCC-HO), which jointly reconstructs hand and object geometry given a single RGB image. We then prompt a text-to-3D generative model using GPT-4(V) to retrieve a 3D object model that matches the object in the image.

  We introduce the SHOWMe dataset which consists of 96 videos, annotated with real and detailed hand-object 3D textured meshes. We consider a rigid hand-object scenario, in which the pose of the hand with respect to the object remains constant during the whole video sequence. This assumption allows us to register sub-millimetre-precise groundtruth 3D scans to the image sequences in SHOWMe.

  This paper presents a method to learn hand-object interaction prior for reconstructing a 3D hand-object scene from a single RGB image. We use the hand shape to constrain the possible relative configuration of the hand and object geometry. We show that HandNeRF is able to reconstruct hand-object scenes of novel grasp configurations more accurately than comparable methods.

  We introduce D3D-HOI: a dataset of monocular videos with ground truth annotations of 3D object pose, shape and part motion during human-object interactions. Our dataset consists of several common articulated objects captured from diverse real-world scenes and camera viewpoints. We leverage the estimated 3D human pose for more accurate inference of the object spatial layout and dynamics.
