Welcome to the Watertight Models Track of SHape REtrieval Contest 2007

Why SHREC?

The aim of SHREC '07 is to provide a common benchmark for the evaluation of the effectiveness of 3D-shape retrieval algorithms. This year the competition is organized into different tracks. This page addresses the Watertight Models track.

Description of the track: Watertight Models

The collection to search in is made of 400 watertight models, i. e. object models represented by seamless surfaces (without defective holes or gaps). Each model will be used in turn as a query against the remaining part of the database. For a given query, the goal of the track is to retrieve the most similar objects. The relevance, marginal relevance or non-relevance of the models for a given query, i.e. the ground truth, will be established a priori. The performance of the algorithms will be evaluated using the measures and tools developed in SHREC '06.

What you need to do to participate

Each participant is requested to:

• register to the track by sending an email to daniela.giorgiATge.imati.cnr.it with the topic "Registration for SHREC07: watertight models track" as Object; you will receive an answer with the instructions to...
• ...download the model collection (.off files), which will be available from the 11^th to the 13^th of April 2007;
• provide by the 13^th of April 2007 a plain ASCII file with the 400*400 dissimilarity matrix, where each entry (i,j) is the distance between models i and j (notice that the lower the value of the entry (i,j), the more you trust the similarity between i and j). Up to 3 dissimilarity matrices may be submitted, resulting from different runs. Each run may be a different algorithm, or a different parameter setting;
• provide the program (binary code) that generated the results submitted;
• submit a summary (up to 4 pages) of the method proposed.
