SHREC2023 - 3D Shape Retrieval Challenge 2023
http://www.shrec.net/

At Eurographics 2023 Symposium on 3D Object Retrieval, 31 August, 1 September 2023

Nota bene: Full paper submissions will follow a two-stage review process and will be published in the international journal Computes & Graphics upon acceptance.

We strongly encourage to consider the graphics replicability stamp initiative, http://www.replicabilitystamp.org/, and to apply for this additional sign of recognition.

Introduction

The general objective of the 3D Shape Retrieval Challenge is to evaluate the effectiveness of 3D-shape retrieval algorithms. SHREC2023 is the eithteenth edition of the challenge. Like previous years, it is organized in conjunction with the Eurographics Symposium on 3D Object Retrieval, where the results will be reviewed and presented at the symposium.

Thanks to the efforts of previous track organizers, SHREC already provides many resources to compare and evaluate 3D retrieval methods. For this year's contest, we aim to explore new and updated tracks. Therefore, the participants are invited to have an active role in the organization of the event. This includes proposing track themes, building or acquiring a training and test collection, and deciding upon the queries, relevance assessment, and performance measures.

The participants of each track will collectively write a paper, which will be peer reviewed, and published in Computers & Graphics upon acceptance. At least one author per track must register for the symposium, and present the results. The registration must be unique for the paper, multiple papers on one registration does not count. We also cordially invite all other participants of a track to register and attend the workshop.

Tracks

The following tracks are organized. For description of tasks, the collections, queries, the evaluation procedure, and time schedule, follow the links or contact the track organizer.

Procedure

The following list is a step-by-step description of the activities:

• Track organizers have sent their proposal describing the envisioned task, collection, queries, ground truth, evaluation method, and expected number of participants.
• The tracks are selected, and are listed at the SHREC web page. The track organizers start up their track.
• Participants register for the tracks they want to participate in.
• Each track is performed according to its own schedule, compliant with the worskop submission and reviewing schedule.
• The track organizers collect the results.
• The track results are combined into a joint paper. Papers are subject to peer review, accepted journal papers are published in Computers & Graphics.
• The description of the tracks and their results are presented at the Eurographics Symposium on 3D Object Retrieval, 31 August, 1 September 2023.
