Vision Recognition using Discriminant Sparse Optimization Learning
Qingxiang Feng, Yicong Zhou
To better select the correct training sample and obtain the robust representation of the query sample, this paper proposes a discriminant-based sparse optimization learning model.…
Discriminant Projection Representation-based Classification for Vision Recognition
Qingxiang Feng, Yicong Zhou
Representation-based classification methods such as sparse representation-based classification (SRC) and linear regression classification (LRC) have attracted a lot of attentions.…
Color Face Recognition using High-Dimension Quaternion-based Adaptive Representation
Qingxiang Feng, Yicong Zhou
Recently, quaternion collaborative representation-based classification (QCRC) and quaternion sparse representation-based classification (QSRC) have been proposed for color face rec…
Polyhedron Volume-Ratio-based Classification for Image Recognition
Qingxiang Feng, Jeng-Shyang Pan, Jar-Ferr Yang +1
In this paper, a novel method, called polyhedron volume ratio classification (PVRC) is proposed for image recognition
