Action Classification with Locality-constrained Linear Coding
Hossein Rahmani, Arif Mahmood, Du Huynh +1
We propose an action classification algorithm which uses Locality-constrained Linear Coding (LLC) to capture discriminative information of human body variations in each spatiotempo…
HOPC: Histogram of Oriented Principal Components of 3D Pointclouds for Action Recognition
Hossein Rahmani, Arif Mahmood, Du Q. Huynh +1
Existing techniques for 3D action recognition are sensitive to viewpoint variations because they extract features from depth images which change significantly with viewpoint. In co…
Histogram of Oriented Principal Components for Cross-View Action Recognition
Hossein Rahmani, Arif Mahmood, Du Huynh +1
Existing techniques for 3D action recognition are sensitive to viewpoint variations because they extract features from depth images which are viewpoint dependent. In contrast, we d…
Optimizing Auto-correlation for Fast Target Search in Large Search Space
Arif Mahmood, Ajmal Mian, Robyn Owens
In remote sensing image-blurring is induced by many sources such as atmospheric scatter, optical aberration, spatial and temporal sensor integration. The natural blurring can be ex…
Semi-supervised Spectral Clustering for Classification
Arif Mahmood, Ajmal S. Mian
We propose a Classification Via Clustering (CVC) algorithm which enables existing clustering methods to be efficiently employed in classification problems. In CVC, training and tes…
