AR paper outline

Camera zoom has not been considered in most AR systems. Since our algorithm targets an AR system for broadcasting, the broadcast-level camera with a zoom lens must be considered.

The target is detected by SURF, ferns, or GPU-SIFT.

PatchTracker with linear motion model.
motion blur model (locate the last point of the motion blur).

Online camera calibration by Zhang → R, t, f estimated.

f is restricted to vary smoothly.
