HOPC: Histogram of Oriented Principal Components of 3D Pointclouds for Action Recognition

17 Aug 2014 Hossein Rahmani Arif Mahmood Du. Q. Huynh Ajmal Mian

Existing techniques for 3D action recognition are sensitive to viewpoint variations because they extract features from depth images which change significantly with viewpoint. In contrast, we directly process the pointclouds and propose a new technique for action recognition which is more robust to noise, action speed and viewpoint variations... (read more)
