This video demonstrated our online patch learning & detection algorithm on the iPhone 3GS.
Our algorithm learns the appearance of planar targets in situ and the target is detected in real-time on mobile phones. Although the fronto-parallel view of the target is unavailable, our method can generate the frontal view automatically.
The algorithm is detailed in our ISMAR 2010 paper: W. Lee, Y. Park, V. Lepetit, W.Woo, "Point-and-Shoot for Ubiquitous Tagging on Mobile Phones," International Symposium on Mixed and Augmented Reality (ISMAR), 2010.
