Abstract

I will present our recent approach to the problem of establishing semantic correspondences between images depicting different instances of the same object or scene category. Previous approaches focus on either combining a spatial regularizer with hand-crafted features, or learning a correspondence model for appearance only. We propose instead a convolutional neural network architecture, called SCNet, for learning a geometrically plausible model for semantic correspondence. SCNet uses region proposals as matching primitives, and explicitly incorporates geometric consistency in its loss function. It is trained on image pairs obtained from the PASCAL VOC 2007 keypoint dataset, and a comparative evaluation on several standard benchmarks demonstrates that the proposed approach substantially outperforms both recent deep learning architectures and previous methods based on hand-crafted features.

 

Biography

Minsu Cho is an assistant professor in the department of Computer Science and Engineering at POSTECH. He obtained his PhD in 2012 from Seoul National University, Korea, and worked as a researcher (starting research position) in the Inria WILLOW team at the Department of Computer Science, École Normale Supérieure (ENS), Paris, France, until 2016. His research has focused on the interplay between computer vision and machine learning, especially in the problems of graph-based object matching and learning. His recent research investigates unsupervised or minimally-supervised object discovery, localization, matching, and tracking in images and videos.
