Summary
4D Humans refers to the reconstruction of temporally consistent 3D human models, the 4th dimension being time. Starting from monocular or multi-view image sequences, the objective is to recover human shape, pose, motion, and appearance in a coherent representation.
Despite significant progress, current approaches follow different modeling paradigms, each with clear limitations. Parametric models such as SMPL provide structured and controllable representations but lack geometric detail, while neural methods such as NeRF and 3D Gaussian Splatting improve visual fidelity but struggle with controllability and canonical representations. High-quality digital humans achieve strong realism, but rely on complex acquisition setups or manual effort.
The 4D Human Workshop (4DH) focuses on image- and video-based approaches to 4D human reconstruction, addressing open challenges and emerging solutions toward realistic, controllable, and scalable human representations.

Call for Papers
The 4D Human Workshop (4DH) invites submissions on methods and applications for reconstructing temporally consistent 3D human models from image and video data.
We welcome contributions addressing a broad range of topics related to 4D human reconstruction, including:
- 4D human reconstruction from monocular or multi-view video
- Parametric human models (e.g., SMPL and related extensions)
- Neural representations (NeRF, 3D Gaussian Splatting, implicit models)
- Modeling of human motion and temporal consistency
- Human appearance, rendering, and relighting
- Multi-person and interaction modeling
- Datasets and benchmarks for dynamic human capture
- Applications in AR/VR, robotics, healthcare, and sports
The workshop will be a half-day event and accepts two types of submissions: original contributions and previously published papers.
Original Contributions
Original papers will be included in the ICIP 2026 proceedings and will undergo a double-blind peer review process.
- Papers must not exceed 5 pages of technical content, including all figures and references
- An optional 6th page may be used for references only
- Submissions must follow the ICIP 2026 format
- Authors are encouraged to review the ICIP submission guidelines: Author Kit
Previously Published Papers
Previously published work can be presented as posters during the workshop and will not be included in the proceedings.
- Submissions will be selected based on relevance and available presentation capacity
- Contributors are asked to submit a 2-page abstract to the organizers at:
Submission Instructions
