gDT-IV 2025

About
In this workshop, we define Digital Twins as 3D models enriched with processes and semantic connections, similar to those in computer game environments. These models can range in fidelity from simplified 3D representations (Digital Cousins) to highly accurate reconstructions of real-world counterparts (Digital Twins). Our focus will be on methodologies and understanding required to improve the accuracy of these reconstructions and their associated processes using visual data, advancing from digital approximations to true Digital Twins. 3D Gaussian Splatting (3DGS) and diffusion models, have demonstrated impressive success in generating 3D representations from images and video. The next frontier in 3D representation is enriching models by integrating both physical and semantic object properties through generative AI and retrieval-based approaches.

TBA		Keynote 1: Matthias Nießner Technical University of Munich Title: Photo-realistic AI Avatars Abstract In this lecture, I will talk about our latest research on creating photo-realistic AI Avatars. Here, the main goal is to create virtual characters that can are visually indistinguishable from photos and videos of real people. Further, we aim to control such avatars with multi-modal control signals such as animation rigs, text, or voice in order to replicate real-world conversations and leverage our avatars for 3D content creation. Ultimately, the goal is to witness the evolution of photos and videos into interactive, holographic 3D content that is indistinguishable from the physical reality. To this end, we focus on the possibility of capturing and sharing 3D photos with friends, family, or through social media platforms. Imagine the ability to comprehensively document historical events along with the participating people for future generations, or to generate content for upcoming applications in augmented and virtual reality.

Call for Papers

Targeted Topics

The gDT-IV Workshop at ICCV 2025 welcomes submissions on all aspects of generating digital twins from images and videos, especially (but not limited to):

Applications of digital twins in robotics, media content creation, AI-driven video synthesis, interior design, construction monitoring, and gaming.
Streaming and compression techniques for sharing large 3D scenes over the web.
Synchronization of the Digital Twin model with the video stream.
3D Gaussian Splatting (3DGS) and its extensions for dynamic scenes.
Lighting variations, shadows, material properties, and reflections in 3DGS reconstruction.
Modeling articulated object parts and their motion constraints from video (e.g., cabinets).
Inpainting and completion techniques for occluded regions in complex indoor scenes.
Retrieval-based and generative hybrid pipelines for 3D object and scene creation.
Learning object properties (mass, softness, friction) from videos.
Physics-informed 3D generation, blending physical simulation with visual generation.
Semantic 3D segmentation for scene understanding (object-level vs. fine-grained).

Submission Tracks

We will have two submission tracks:

Archival Track

Papers should present original, unpublished work and follow a strict double-blind review. Manuscripts must be prepared with the ICCV 2025 Author Kit and be 4–8 pages (references and appendices may extend beyond 8 pages). Accepted papers will appear in the official ICCV 2025 Workshop Proceedings, and authors will present in person.

We follow the same policy as the main ICCV conference for this track. By submitting to this track, the authors acknowledge that it has not been previously published or accepted for publication in substantially similar form in any peer-reviewed venue including journal, conference or workshop, or archival forum. Furthermore, no publication substantially similar in content (defined as having 20 percent or more overlap) has been or will be registered or submitted to this or another conference, workshop, or journal during the review period. Violation of any of these conditions will lead to rejection, and will be reported to the other venue to which the submission was sent. For more details policy, please check the official policy at ICCV 2025.

Submit to the Archival Track via: OpenReview

Non-Archival Track

This flexible track welcomes a wider range of contributions:
- Extended abstracts & short papers — up to 4 pages, suitable for work in progress, negative results, or position papers. References and appendices may extend beyond 4 pages.
- Previously published work — including papers accepted at ICCV 2025 or other venues in the last year.
All submissions should be formated with the ICCV 2025 Author Kit. Submissions remain double-blind for review but will not appear in proceedings. Thus, papers that have already been published at major conferences are also welcome. Authors may also submit their work to future conferences or journals after acceptance to this workshop.
