Profile HMMs for skeleton-based human action recognition

作者：

Highlights：

• Profile HMMs are introduced to human action recognition using 3D positions of joints.

• The structure information of action sequences can be found through profile analysis.

• The algorithm applied on profile HMMs is superior to ones applied on classical HMMs.
