Fast Object Tracking
for Direct Manipulation Video Navigation


What is DRAGONEye?

DRAGONEye is a new version of DRAGON, our direct-manipulation interaction technique for frame-accurate navigation in video scenes. Through the use of a novel object tracking algorithm, we could get rid of the substantial pre-processing time that DRAGON required. At the same time, DRAGONEye is more robust to object occlusions.

The People Behind DRAGONEye

DRAGONEye is a research project by Moritz Wittenhagen, Thorsten Karrer, Malte Weiss, Jan Borchers and others at the Media Computing Group. It is funded in part through the German B-IT Foundation, the UMIC DFG Excellence Initiative, and the HumTec Human Technology Center.
