Robust action recognition using local motion and group sparsity

作者:

Highlights:

• Dense sampling based approaches dilute the information about motions of interest.

• The proposed algorithm identifies local motions of interest using group sparsity.

• We emphasize the local motion using multiple kernel method.

• It alleviates the effect of the contaminated descriptors.

• We demonstrate that the proposed method is robust for realistic video sequences.
