Daniela Lopez de Luise We invite you to participate in the SHREC 2025 track on “Retrieval and Segmentation of Multiple Relief Patterns”.
Relief patterns (or geometric textures) can be defined as a repeated pattern of local surface corrugation, independent of the global shape of the object or the photometric properties of the surface.
The analysis of relief patterns has applications in various fields requiring the characterization of regular (or quasi-regular) structures, such as fabric inspection, medical imaging, and the restoration of historic artifacts.
The study of relief patterns remains an underexplored problem within 3D shape analysis, which has traditionally focused on tasks such as shape correspondence, classification, and segmentation of parts or instances.
Nonetheless, with the release of increasingly large and complex datasets (e.g, Objaverse-XL), there is a growing need for powerful tools capable of analyzing objects across multiple scales, taking into account both global and local geometric properties.
This track focuses on the local characteristics of an object, which can convey critical information about material properties or semantic attributes that may be difficult to extract when considering only the shape of the object.
The track is structured into a main task and an optional challenge.
Participants are required to solve two problems:
- Pattern retrieval: Given a query mesh, participants are required to identify whether and where the relief patterns present in the query are located on the surface of a 3D model from a retrieval dataset.
- Optional challenge – Pattern segmentation: Participants are required to segment the different relief patterns present on the surface of 3D models in the query dataset.
For more detailed information on the track, registration, and important dates, please visit the official track webpage.
Participants are invited to submit their results along with a description of their methods, which will be included in a joint paper.
All participants will be co-authors of the track paper, which will be submitted to and published upon acceptance in the international journal Computer & Graphics.
If you have any questions, please do not hesitate to contact Gabriele Paolini (email: gabriele.paolini1@unifi.it).
Feel free to share this invitation email with colleagues, students, and anyone who may be interested.
We look forward to your participation in SHREC 2025.
