Learning The Structure Of Objects From Web Supervision

While recent research in image understanding has often focused on recognizing more types of objects, understanding more about the objects is just as important. Learning about object parts and their geometric relationships has been extensively studied before, yet learning large space of such concepts remains elusive due to the high cost of collecting detailed object annotations for supervision. The key contribution of this paper is an algorithm to learn geometric and semantic structure of objects and their semantic parts automatically, from images obtained by querying the Web. We propose a novel embedding space where geometric relationships are induced in a soft manner by a rich set of non-semantic mid-level anchors, bridging the gap between semantic and non-semantic parts. We also show that the resulting embedding provides a visually-intuitive mechanism to navigate the learned concepts and their corresponding images.
