AvatarPoser: Articulated Full-Body Pose Tracking from Sparse Motion Sensing

1 code implementation27 Jul 2022 Jiaxi Jiang, Paul Streli, Huajian Qiu, Andreas Fender, Larissa Laich, Patrick Snape, Christian Holz

In this paper, we present AvatarPoser, the first learning-based method that predicts full-body poses in world coordinates using only motion input from the user's head and hands.

DenseReg: Fully Convolutional Dense Shape Regression In-the-Wild

no code implementations CVPR 2017 Riza Alp Guler, Yuxiang Zhou, George Trigeorgis, Epameinondas Antonakos, Patrick Snape, Stefanos Zafeiriou, Iasonas Kokkinos

We define the regression task in terms of the intrinsic, U-V coordinates of a 3D deformable model that is brought into correspondence with image instances at training time.

Learning the Multilinear Structure of Visual Data

no code implementations CVPR 2017 Mengjiao Wang, Yannis Panagakis, Patrick Snape, Stefanos Zafeiriou

To extract these modes of variations from visual data, several supervised methods, such as the TensorFaces, that rely on multilinear (tensor) decomposition (e. g., Higher Order SVD) have been developed.

Face Normals "In-The-Wild" Using Fully Convolutional Networks

no code implementations CVPR 2017 George Trigeorgis, Patrick Snape, Iasonas Kokkinos, Stefanos Zafeiriou

In this work we pursue a data-driven approach to the problem of estimating surface normals from a single intensity image, focusing in particular on human faces.

DenseReg: Fully Convolutional Dense Shape Regression In-the-Wild

no code implementations CVPR 2017 Riza Alp Güler, George Trigeorgis, Epameinondas Antonakos, Patrick Snape, Stefanos Zafeiriou, Iasonas Kokkinos

As such our network can provide useful correspondence information as a stand-alone system, while when used as an initialization for Statistical Deformable Models we obtain landmark localization results that largely outperform the current state-of-the-art on the challenging 300W benchmark.

A Comprehensive Performance Evaluation of Deformable Face Tracking "In-the-Wild"

1 code implementation18 Mar 2016 Grigorios G. Chrysos, Epameinondas Antonakos, Patrick Snape, Akshay Asthana, Stefanos Zafeiriou

Recently, technologies such as face detection, facial landmark localisation and face recognition and verification have matured enough to provide effective and efficient solutions for imagery captured under arbitrary conditions (referred to as "in-the-wild").

Face Flow

no code implementations ICCV 2015 Patrick Snape, Anastasios Roussos, Yannis Panagakis, Stefanos Zafeiriou

In this paper, we propose a method for the robust and efficient computation of multi-frame optical flow in an expressive sequence of facial images.

Automatic Construction Of Robust Spherical Harmonic Subspaces

no code implementations CVPR 2015 Patrick Snape, Yannis Panagakis, Stefanos Zafeiriou

In this paper we propose a method to automatically recover a class specific low dimensional spherical harmonic basis from a set of in-the-wild facial images.

Kernel-PCA Analysis of Surface Normals for Shape-from-Shading

no code implementations CVPR 2014 Patrick Snape, Stefanos Zafeiriou

We propose a kernel-based framework for computing components from a set of surface normals.
