Visual tracking of non-rigid objects with partial occlusion through elastic structure of local patches and hierarchical diffusion

作者：

Highlights：

• We propose a tracking method to solve both the problem of partial occlusions and non-rigid deformations in real-time.

• The target object is modeled through an elastic structure of local patches for robust performance.

• Hierarchical diffusion method is proposed to obtain an acceptable solution in real time.

• Extensive evaluation shows that the proposed method outperforms state-of-the-art.
