December 8, 2012: we fixed several problems in the ground-truth of our
modeled irons, tele-aliens, and chairs.
</p>
<br />
<h2>Overview</h2>
<p>
The goal of this work is to provide data for quantitative analysis of
how people consistently segment a set of shapes and for evaluation of
our
<a href="http://www.yunhaiwang.net/public_html/ssl/ssl.htm" target="_blank">active co-analysis algorithm</a>. To
build the dataset, we have collected 11 sets of shapes which possess a
consistent ground-truth segmentation and labeling. Among them, seven
sets from the dataset of
<a
href="http://www.cs.sfu.ca/~ovankaic/personal/cosegmentation/"
target="_blank"
>Sidi et al. [2011]</a
>. Since we consider the labeling of large sets as one of the main
motivations of our work, we created three additional large sets:
<a href="http://www.yunhaiwang.net/public_html/ssl/data/Tele-aliens/image.jpg" target="_blank">tele-alines</a>,
<a href="http://www.yunhaiwang.net/public_html/ssl/data/Tele-aliens/image.jpg" target="_blank">vases</a> and
<a href="http://www.yunhaiwang.net/public_html/ssl/data/Tele-aliens/image.jpg" target="_blank">chairs</a>. These
three sets consists of 200, 300, 400 shapes, respetively. We also
created a small but challenging set of
<a href="http://www.yunhaiwang.net/public_html/ssl/data/Irons/image.jpg" target="_blank">irons</a>.
