Sparseness Meets Deepness: 3D Human Pose Estimation from Monocular Video
Xiaowei Zhou, Menglong Zhu, Spyridon Leonardos +2
This paper addresses the challenge of 3D full-body human pose estimation from a monocular image sequence. Here, two cases are considered: (i) the image locations of the human joint…
Sparse Representation for 3D Shape Estimation: A Convex Relaxation Approach
Xiaowei Zhou, Menglong Zhu, Spyridon Leonardos +1
We investigate the problem of estimating the 3D shape of an object defined by a set of 3D landmarks, given their 2D correspondences in a single image. A successful approach to alle…
Multi-Image Matching via Fast Alternating Minimization
Xiaowei Zhou, Menglong Zhu, Kostas Daniilidis
In this paper we propose a global optimization-based approach to jointly matching a set of images. The estimated correspondences simultaneously maximize pairwise feature affinities…
Pose and Shape Estimation with Discriminatively Learned Parts
Menglong Zhu, Xiaowei Zhou, Kostas Daniilidis
We introduce a new approach for estimating the 3D pose and the 3D shape of an object from a single image. Given a training set of view exemplars, we learn and select appearance-bas…
