Face recognition via compact second order image gradient orientations
He-Feng Yin, Xiao-Jun Wu, Xiaoning Song
Conventional subspace learning approaches based on image gradient orientations only employ the first-order gradient information. However, recent researches on human vision system (…
MOON: Multi-Hash Codes Joint Learning for Cross-Media Retrieval
Donglin Zhang, Xiao-Jun Wu, He-Feng Yin +1
In recent years, cross-media hashing technique has attracted increasing attention for its high computation efficiency and low storage cost. However, the existing approaches still h…
Affine Non-negative Collaborative Representation Based Pattern Classification
He-Feng Yin, Xiao-Jun Wu, Zhen-Hua Feng +1
During the past decade, representation-based classification methods have received considerable attention in pattern recognition. In particular, the recently proposed non-negative r…
Learning efficient structured dictionary for image classification
Zi-Qi Li, Jun Sun, Xiao-Jun Wu +1
Recent years have witnessed the success of dictionary learning (DL) based approaches in the domain of pattern classification. In this paper, we present an efficient structured dict…
Face Verification via learning the kernel matrix
Ning Yuan, Xiao-Jun Wu, He-Feng Yin
The kernel function is introduced to solve the nonlinear pattern recognition problem. The advantage of a kernel method often depends critically on a proper choice of the kernel fun…
Multiplication fusion of sparse and collaborative-competitive representation for image classification
Zi-Qi Li, Jun Sun, Xiao-Jun Wu +1
Representation based classification methods have become a hot research topic during the past few years, and the two most prominent approaches are sparse representation based classi…
