Query: Semantic Correspondence via 2D-3D-2D Cycle   Visual semantic correspondence is an important topic in computer vision and
could help machine understand objects in our daily life. However, most previous
methods directly train on correspondences in 2D images, which is end-to-end but
loses plenty of information in 3D spaces. In this paper, we propose a new
method on predicting semantic correspondences by leveraging it to 3D domain and
then project corresponding 3D models back to 2D domain, with their semantic
labels. Our method leverages the advantages in 3D vision and can explicitly
reason about objects self-occlusion and visibility. We show that our method
gives comparative and even superior results on standard semantic benchmarks. We
also conduct thorough and detailed experiments to analyze our network
components. The code and experiments are publicly available at
