Applications of Face Analysis and Modeling in Media Production
Found in: IEEE MultiMedia
By Darren Cosker,Peter Eisert,Oliver Grau,Peter J.B. Hancock,Jonathan McKinnell,Eng-Jon Ong
Issue Date:October 2013
pp. 18-27
Facial expressions play an important role in day-by-day communication as well as media production. This article surveys automatic facial analysis and modeling methods using computer vision techniques and their applications for media production. The authors...
Semantic Kernels Binarized - A Feature Descriptor for Fast and Robust Matching
Found in: Visual Media Production, Conference for
By Frederik Zilly,Christian Riechert,Peter Eisert,Peter Kauff
Issue Date:November 2011
pp. 39-48
This paper presents a new approach for feature description used in image processing and robust image recognition algorithms such as 3D camera tracking, view reconstruction or 3D scene analysis. State of the art feature detectors distinguish interest point ...
Creation of High-Resolution Video Panoramas of Sport Events
Found in: Multimedia, International Symposium on
By Christoph Fehn, Christian Weissig, Ingo Feldmann, Markus Muller, Peter Eisert, Peter Kauff, Hans BloB
Issue Date:December 2006
pp. 291-298
This paper describes an approach for creating high-resolution video panoramas of large-scale sport events. In an exemplary football scenario, we used two ARRIFLEX D-20
3D Video and Free Viewpoint Video - Technologies, Applications and MPEG Standards
Found in: Multimedia and Expo, IEEE International Conference on
By Aljoscha Smolic, Karsten Mueller, Philipp Merkle, Christoph Fehn, Peter Kauff, Peter Eisert, Thomas Wiegand
Issue Date:July 2006
pp. 2161-2164
An overview of 3D and free viewpoint video is given in this paper with special focus on related standardization activities in MPEG. Free viewpoint video allows the user to freely navigate within real world visual scenes, as known from virtual worlds in com...
Towards Robust Intuitive Vision-Based User Interfaces
Found in: Multimedia and Expo, IEEE International Conference on
By Oliver Schreer, Peter Eisert, Peter Kauff, Ralf Tanger, Roman Englert
Issue Date:July 2006
pp. 69-72
In future videocommunication services, the user's communication device, such as PC, laptop, PDA or mobile phone is equipped with new interaction modalities. These can be cameras and microphones on the capturing side and speech synthesis and video/3D graphi...
Automatic Acquisition of Time-Slice Image Sequences
Found in: Visual Media Production, Conference for
By Markus Kettern, David C. Schneider, Benjamin Prestele, Frederik Zilly, Peter Eisert
Issue Date:November 2010
pp. 40-48
Acquisition of consistent multi-camera image data such as for time-slice sequences (widely known by their use as cinematic effects, e.g. in “The Matrix”) is a challenging task, especially when using low-cost image sensors. Many different steps such as came...
Adaptive color classification for structured light systems
Found in: Computer Vision and Pattern Recognition Workshop
By Philipp Fechteler, Peter Eisert
Issue Date:June 2008
pp. 1-7
We present a system to capture high accuracy 3D models of faces by taking just one photo without the need of specialized hardware, just a consumer grade digital camera and beamer. The proposed 3D face scanner utilizes structured light techniques: A colored...
Tracking deformable surfaces with optical flow in the presence of self occlusion in monocular image sequences
Found in: Computer Vision and Pattern Recognition Workshop
By Anna Hilsmann, Peter Eisert
Issue Date:June 2008
pp. 1-6
In this paper, we present a direct method for deformable surface tracking in monocular image sequences. We use the optical flow constraint instead of working with distinct features. The optical flow field is regularized with a 2-dimensional mesh-based defo...
3-D Object Reconstruction Using Spatially Extended Voxels and Multi-Hypothesis Voxel Coloring
Found in: Pattern Recognition, International Conference on
By Eckehard Steinbach, Bernd Girod, Peter Eisert, Arnulf Betz
Issue Date:September 2000
pp. 1774
In this paper, we describe a voxel-based 3-D reconstruction technique from multiple calibrated camera views that makes explicit use of the finite size footprint of a voxel when projected into the image plane. We derive a class of computationally efficient ...
Analyzing Facial Expressions for Virtual Conferencing
Found in: IEEE Computer Graphics and Applications
By Peter Eisert, Bernd Girod
Issue Date:September 1998
pp. 70-78
We present a method for estimating 3D motion from 2D image sequences showing head and shoulder scenes typical of video telephone and teleconferencing applications. Our 3D model specifies the color and shape of the person in the video. Additionally, the mod...
