| - |   abstract = {In Augmented Reality applications, the human | + |  | 
| - | perception is enhanced with computer-generated | + |  | 
| - | graphics. These graphics must be exactly registered | + |  | 
| - | to real objects in the scene and this requires | + |  | 
| - | an effective Augmented Reality system to track the | + |  | 
| - | user’s viewpoint. In this paper, a robust tracking algorithm | + |  | 
| - | based coded fiducials is presented. Square | + |  | 
| - | targets are identified and pose parameters are computed | + |  | 
| - | using a hybrid approach based on a direct | + |  | 
| - | method combined with the Kalman filter. An important | + |  | 
| - | factor for providing a robust Augmented Reality | + |  | 
| - | system is the correct handling of targets occlusions | + |  | 
| - | by real scene elements. To overcome tracking | + |  | 
| - | failure due to occlusions, we extend our method using | + |  | 
| - | an optical flow approach to track visible points | + |  | 
| - | and maintain virtual graphics overlaying when targets | + |  | 
| - | are not identified. Our proposed real time algorithm | + |  | 
| - | is tested with different camera viewpoints | + |  | 
| - | under various image conditions and shows to be accurate | + |  | 
| - | and robust.} | + |  |
