Recovering 3D full-body human pose is a challenging problem with many applications.

Sparseness Meets Deepness: 3D Human Pose Estimation from Monocular Video

1 code implementation • CVPR 2016 • Xiaowei Zhou, Menglong Zhu, Spyridon Leonardos, Kosta Derpanis, Kostas Daniilidis

Here, two cases are considered: (i) the image locations of the human joints are provided and (ii) the image locations of joints are unknown.

Sparse Representation for 3D Shape Estimation: A Convex Relaxation Approach

no code implementations • 14 Sep 2015 • Xiaowei Zhou, Menglong Zhu, Spyridon Leonardos, Kostas Daniilidis

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 Metric Parametrization for Trifocal Tensors With Non-Colinear Pinholes

no code implementations • CVPR 2015 • Spyridon Leonardos, Roberto Tron, Kostas Daniilidis

In this work, we investigate a new parametrization of the trifocal tensor for calibrated cameras with non-colinear pinholes obtained from a quotient Riemannian manifold.
