Prototype learning and collaborative representation using Grassmann manifolds for image set classification

作者:

Highlights:

• Principle component and variation subspaces are constructed for an over-complete dictionary.

• A novel prototype and variation model (P+V) based collaborative representation for Grassmann manifolds is proposed to deal with image set classification naturally.

• Previous special matrices are generalized to common sparse matrices.

• Experimental results show the superiorities of our methods.
