RTcams: A New Perspective on Nonphotorealistic Rendering from Photographs
Found in: IEEE Transactions on Visualization and Computer Graphics
By Peter M. Hall, John P. Collomosse, Yi-Zhe Song, Peiyi Shen, Chuan Li
Issue Date:September 2007
pp. 966-979
<p><b>Abstract</b>—We introduce a simple but versatile camera model that we call the Rational Tensor Camera (RTcam). RTcams are well principled mathematically and provably subsume several important contemporary camera models in both compu...
 
Mobile augmented reality based 3D snapshots
Found in: Mixed and Augmented Reality, IEEE / ACM International Symposium on
By Peter Keitler, Frieder Pankratz, Bjorn Schwerdtfeger, Daniel Pustka, Wolf Rodiger, Gudrun Klinker, Christian Rauch, Anup Chathoth, John Collomosse, Yi-Zhe Song
Issue Date:October 2009
pp. 199-200
We describe a mobile augmented reality application that is based on 3D snapshotting using multiple photographs. Optical square markers provide the anchor for reconstructed virtual objects in the scene. A novel approach based on pixel flow highly improves t...
 
Abstract Art by Shape Classification
Found in: IEEE Transactions on Visualization and Computer Graphics
By Yi-Zhe Song,D. Pickup, Chuan Li,P. Rosin,P. Hall
Issue Date:August 2013
pp. 1252-1263
This paper shows that classifying shapes is a tool useful in nonphotorealistic rendering (NPR) from photographs. Our classifier inputs regions from an image segmentation hierarchy and outputs the
 
Modeling and generating moving trees from video
Found in: ACM Transactions on Graphics (TOG)
By Chuan Li, Oliver Deussen, Peter Hall, Phil Willis, Yi-Zhe Song, Chuan Li
Issue Date:December 2011
pp. 1-15
We present a probabilistic approach for the automatic production of tree models with convincing 3D appearance and motion. The only input is a video of a moving tree that provides us an initial dynamic tree model, which is used to generate new individual tr...
