SHREC 15 Track

3D Object Retrieval with Multimodal Views

Download Dataset

In this track, we provide 311 objects as query objects and 505 objects as testing objects. For each object, we will provide two versions. One version includes 73 images. Other version includes 721 images For each version, we both provide RGB image, Depth image and Mask image. We build one ftp server for downloading this dataset. The IP of this ftp server is: When participants send email to or for registering, we will send username and password to participation for downloading this dataset.

Note: The participants also need to download and file Agreement and Disclaimer Form and send it back to us with your register email. We will then email you the instructions to download the dataset.

For our track, The 505 objects belong to 61 categories and the number of objects in each category ranges from 1 to 20. Here the categories containing no less than 10 objects are selected as the queries and there are 23 categories of objects are employed here. For these 23 categories, there are 311 objects.

In our track, two 3D object retrieval tasks are launched, which employ the complete version (721 images) and the concise version (73 images) of data respectively. In each task, these 318 objects are used as the query object once. For each object, we provide two kinds of image sets (73 images and 721 iamges) respectively. Thus, a success results should includes 2 files, which show the retrieval results base on different image sets. If the participants have more then one method and more than one result, they should provide different folders and each folder includes one results. The filename of folder should be named as the name of method. Meanwhile, participants should provide corresponding code according different results.

For example, the method used by user is name as CCFV. Author should build a folder, which is named as author-CCFV, where author should be replaced with the first author's surname. CCFV is the method's name. This folder should include two files. The names of files is 73.txt and 721.txt. In this track, we provide 311 objects as query dataset and 505 objects as test dataset. Thus, these two txt files should include 311 row and 505 column. Each row represents the retrieval result of one query. The first column represents query model and the rest of columns represents the retrieval results. Each result separated by Spaces.
