We describe a monocular 'eye in hand' approach to acquire 3-D information of a scene in a robotic environment. Networked 3D virtual environments allow multiple users to interact over the Internet by means of avatars and to get some feeling of a virtual telepresence.

However, avatar control may be tedious. 3D sensors for motion capture systems based on 3D sensors have reached the consumer market, but webcams remain more widespread and cheaper.

The proposed demonstration aims at animating a user’s avatar from real time 3D motion capture by monoscopic computer vision, thus allowing virtual telepresence to anyone using a personal computer with a webcam or a camera-phone.

Estimation of depth and motion from pairs of images goes back to Longuet-Higgins [25]. The underlying 3D ge-ometry is a consolidated field, which is well covered in text-books [17,10]. State-of-the-art systems [14,42] allow for reconstructions of large scenes including whole cities.

This can be formulated either as an incremental or as a batch problem. In incremental methods, images are available one at a time. A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text.

the complexity of road scenes and the need for real-time solutions pose key challenges. This paper proposes a novel framework for monocular traffic scene recognition, relying on a decomposition into high-order and atomic scenes to meet those challenges.

High-order scenes carry semantic meaning useful for AWS applications, while atomic scenes. However, despite significant progress over the last years, there are still unsolved challenges that limit applicability of depth-based monocular full body motion capture.

Algorithms are challenged by very noisy sensor data, (self) occlusions, or other ambiguities implied by the limited information that a depth sensor can extract of the by: 7.

This paper addresses scene understanding in the context of a moving camera, integrating semantic reasoning ideas from monocular vision with 3D information available through structure-from-motion.

Monocular Omnidirectional Head Motion Capture in the Visible Light Spectrum Conventional marker-based optical motion capture methods rely on scene attenuation (e.g.

The network estimates not only depth and motion, but additionally surface normals, optical flow between the images and confidence of the matching.

A crucial component of the approach is a training loss based on spatial relative differences.

This paper presents a facial performance capture system that automatically captures high-fidelity facial performances using uncontrolled monocular videos (e.g., Internet videos).
