Kernelized cross-view quadratic discriminant analysis for person re-identification

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

In person re-identification, Keep It Simple and Straightforward MEtric (KISSME) is known as a practical distance metric learning method. Typically, kernelization improves the performance of metric learning methods. Nevertheless, deriving KISSME on a reproducing kernel Hilbert space is a non-trivial problem. Nyström method approximates the Hilbert space in low-dimensional Euclidean space, and the application of KISSME is straightforward, yet it fails to preserve discriminative information. To utilize KISSME in a discriminative subspace of the Hilbert space, we propose a kernel extension of Cross-view Discriminant Analysis (XQDA) which learns a discriminative low-dimensional subspace, and simultaneously KISSME in the learned subspace. We show with the standard kernel trick, the kernelized XQDA results in the case when the empirical kernel vector is used as the input of XQDA. Experimental results on benchmark datasets show the kernelized XQDA outperforms XQDA and Nyström-KISSME.
