Joint Conditional Random Field of multiple views with online learning for image-based rendering
Found in: Computer Vision and Pattern Recognition, IEEE Computer Society Conference on
By Wenfeng Li, Baoxin Li
Issue Date:June 2008
pp. 1-8
There are many applications, such as image-based rendering, where multiple views of a scene are considered simultaneously for improved analysis through employing strong correlation among the set of pixels corresponding to the same physical scene point. Whi...
Probabilistic Image-Based Rendering with Gaussian Mixture Model
Found in: Pattern Recognition, International Conference on
By Wenfeng Li, Baoxin Li
Issue Date:August 2006
pp. 179-182
One major challenge in traditional image-based rendering is 3D scene reconstruction by estimating accurate dense depth map, which suffers from the ambiguities in textureless or periodically textured regions. Alternatively, statistical methods may be used t...
Virtual View Specification and Synthesis in Free Viewpoint Television Application
Found in: 3D Data Processing Visualization and Transmission, International Symposium on
By Wenfeng Li, Jin Zhou, Baoxin Li, M. Ibrahim Sezan
Issue Date:June 2006
pp. 464-471
In conventional TV, users can get only a single view of a real 3D world. The view is determined not by a user but by the camera position during acquisition. Free viewpoint television (FTV) is a new concept which aims at giving viewers the flexibility to se...
Empowering the Invulnerability of Wireless Sensor Networks through Super Wires and Super Nodes
