Log-Euclidean Metric Learning on Symmetric Positive Definite Manifold with Application to Image Set Classification

The manifold of Symmetric Positive Definite (SPD) matrices has been successfully used for data representation in image set classification. By endowing the SPD manifold with Log-Euclidean Metric, existing methods typically work on vector-forms of SPD matrix logarithms. This however not only inevitabl…
