SHREC2022 - 3D Shape Retrieval Challenge 2022
http://www.shrec.net/

At Eurographics 2022 Symposium on 3D Object Retrieval, 1-2 September 2022

New since 2020: 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. SHREC2022 is the sixteenth 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 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. We also cordially invite all participants of a track to register and attend the workshop.

Procedure

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

1. Track organizers have sent their proposal describing the envisioned task, collection, queries, ground truth, evaluation method, and expected number of participants.
2. The tracks are selected, and are listed at the SHREC web page. The track organizers start up their track.
3. Participants register for the tracks they want to participate in.
4. Each track is performed according to its own time schedule.
5. The track organizers collect the results.
6. The track results are combined into a joint paper, to be submitted for review to Computers & Graphics.
7. The description of the tracks and their results are presented at the Eurographics Symposium on 3D Object Retrieval, 1-2 September 2022.
