1. Introduction•Few of platforms are designed to

different tracking algorithms for AR system

•A novel tracking platform for AR environment, ARStudio, is proposed

•Augmented Reality, AR•Showing the virtual object in real

world

3. Platform design(2/3)

•Speeded Up Robust Features, SURF•Scale- and rotation-invariant

detector and descriptor•With distinctiveness, and

robustness•Can be computed and compared

much faster
