SDFs seamlessly generalize to different shape resolutions and topologies but lack explicit modelling of the underlying 3D geometry. In this work, we exploit the hand structure and use it as guidance for SDF-based shape reconstruction. In particular, we address reconstruction of hands and manipulated objects from monocular RGB images. To this end, we estimate poses of hands and objects and use them to guide 3D reconstruction. More specifically, we predict kinematic chains of pose transformations and align SDFs with highly-articulated hand poses. We improve the visual features of 3D points with geometry alignment and further leverage temporal information to enhance the robustness to occlusion and motion blurs. We conduct extensive experiments on the challenging ObMan and DexYCB benchmarks and demonstrate significant improvements of the proposed method over the state of the art.","url_abs":"https://arxiv.org/abs/2304.11970v1","url_pdf":"https://arxiv.org/pdf/2304.11970v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"gsdf-geometry-driven-signed-distance","repo_url":"https://github.com/zerchen/gSDF","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"pytorch","reach":null}],"tasks":[{"task_slug":"3d-reconstruction","task_name":"3D Reconstruction"},{"task_slug":"3d-shape-reconstruction","task_name":"3D Shape Reconstruction"},{"task_slug":"3d-geometry","task_name":"3D geometry"},{"task_slug":"object-reconstruction","task_name":"Object Reconstruction"},{"task_slug":"hand-object-pose","task_name":"hand-object pose"}],"methods":[{"method_slug":"align","method_name":"ALIGN"}],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/hand-object-pose-on-dexycb","task":"hand-object pose","dataset":"DexYCB","model":"gSDF","rank_in_archive_order":5,"of":9,"metrics":{"ADD-S":"-","Average MPJPE (mm)":"14.4","MCE":"-","OCE":"19.1","Procrustes-Aligned MPJPE":"-"},"uses_additional_data":false}],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=2304.11970","mcp":{"get_harvested_code_for_paper":{"arxiv_id":"2304.11970"}},"developers":"https://syntology.ai/developers","read_at":"2026-09-24T18:15:14+00:00","read_at_is":"when the build read Syntology's graph, not when any sample ran","claim":"Per-sample execution status on synthesized fixtures; not a correctness claim about the paper.
