Hallucinating optimal high-dimensional subspaces

作者：

Highlights：

• Matching appearance subspaces of different scales not addressed in the literature.

• Naïve basis re-projection inadequate.

• Proposed refinement using constrained rotation.

• Closed-form solution for optimal subspace reconstruction.

• Class separation increased up to an order of magnitude.
