Monocular Video-Based Trailer Coupler Detection Using Multiplexer Convolutional Neural Network

no code implementations ICCV 2017 Yousef Atoum, Joseph Roth, Michael Bliss, Wende Zhang, Xiaoming Liu

This paper presents an automated monocular-camera-based computer vision system for autonomous self-backing-up a vehicle towards a trailer, by continuously estimating the 3D trailer coupler position and feeding it to the vehicle control system, until the alignment of the tow hitch with the trailers coupler.

Adaptive 3D Face Reconstruction From Unconstrained Photo Collections

no code implementations CVPR 2016 Joseph Roth, Yiying Tong, Xiaoming Liu

Given a collection of "in-the-wild" face images captured under a variety of unknown pose, expression, and illumination conditions, this paper presents a method for reconstructing a 3D face surface model of an individual along with albedo information.

Unconstrained 3D Face Reconstruction

no code implementations CVPR 2015 Joseph Roth, Yiying Tong, Xiaoming Liu

Second, by leveraging emerging face alignment techniques and our novel normal field-based Laplace editing, a combination of landmark constraints and photometric stereo-based normals drives our surface reconstruction.
