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

   Yousef Atoum, Joseph Roth, Michael Bliss, Wende Zhang, Xiaoming Liu

   This paper presents a monocular camera-based computer vision system for autonomous selfbacking-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. This system is made possible through ...

   Unconstrained 3D Face Reconstruction

   Joseph Roth, Yiying Tong, Xiaoming Liu

   We present an algorithm for "unconstrained" 3D face reconstruction from a 2D photo collection of face images of a subject captured under a diverse variation of poses, expressions, and illuminations, without meta data about the cameras, timing, or light conditions. The output of our algorithm is a true 3D face ...

   Typing Behavior based Continuous User Authentication

   Joseph Roth, Xiaoming Liu, Arun Ross, Dimitris Metaxas

   We hypothesize that an individual computer user has a unique and consistent habitual pattern of Typing Behavior, independent of the text, while typing on a keyboard. This habit manifests itself visually through the shapes and motions of the hands, as well as audibly through the sounds produced when pressing and ...
