More About Covariance Descriptors for Image Set Coding: Log-Euclidean Framework based Kernel Matrix Representation

2 code implementations16 Sep 2019 Kai-Xuan Chen, Xiao-Jun Wu, Jie-Yi Ren, Rui Wang, Josef Kittler

We consider a family of structural descriptors for visual data, namely covariance descriptors (CovDs) that lie on a non-linear symmetric positive definite (SPD) manifold, a special type of Riemannian manifolds.

Component SPD Matrices: A lower-dimensional discriminative data descriptor for image set classification

no code implementations16 Jun 2018 Kai-Xuan Chen, Xiao-Jun Wu

In the domain of pattern recognition, using the SPD (Symmetric Positive Definite) matrices to represent data and taking the metrics of resulting Riemannian manifold into account have been widely used for the task of image set classification.

Riemannian kernel based Nyström method for approximate infinite-dimensional covariance descriptors with application to image set classification

no code implementations16 Jun 2018 Kai-Xuan Chen, Xiao-Jun Wu, Rui Wang, Josef Kittler

We propose a novel framework for representing image sets by approximating infinite-dimensional CovDs in the paradigm of the Nystr\"om method based on a Riemannian kernel.

Multiple Manifolds Metric Learning with Application to Image Set Classification

no code implementations30 May 2018 Rui Wang, Xiao-Jun Wu, Kai-Xuan Chen, Josef Kittler

In image set classification, a considerable advance has been made by modeling the original image sets by second order statistics or linear subspace, which typically lie on the Riemannian manifold.
