From manifold to manifold: Geometry-aware dimensionality reduction for SPD matrices

Harandi, Mehrtash; Salzmann, Mathieu; Hartley, Richard

Description

Representing images and videos with Symmetric Positive Definite (SPD) matrices and considering the Riemannian geometry of the resulting space has proven beneficial for many recognition tasks. Unfortunately, computation on the Riemannian manifold of SPD matrices -especially of high-dimensional ones- comes at a high cost that limits the applicability of existing techniques. In this paper we introduce an approach that lets us handle high-dimensional SPD matrices by constructing a...[Show more]
