Spatio-temporal video error concealment using priority-ranked region-matching (2008)
Yan Chen, Xiaoyan Sun, Feng Wu, Zhengkai Liu, Shipeng Li
Abstract — W hen transmitted over error-prone networks, compressed video sequences may be received with errors. In this paper we propose a priority-ranked region-matching algorithm to recover the...
A Novel Gabor-LDA Based Face Recognition Method (2008)
Yanwei Pang, Lei Zhang, Mingjing Li, Zhengkai Liu, Weiying Ma
Abstract. In this paper, a novel face recognition method based on Gabor-wavelet and linear discriminant analysis (LDA) is proposed. Given training face images, discriminant vectors are computed using...
Neighborhood Preserving Projections (NPP): A Novel Linear Dimension Reduction Method (2008)
Yanwei Pang, Lei Zhang, Zhengkai Liu
Abstract. Dimension reduction is a crucial step for pattern recognition and information retrieval tasks to overcome the curse of dimensionality. In this paper a novel unsupervised linear dimension...
Parallel Image Matrix Compression for Face Recognition (2008)
Dong Xu, Shuicheng Yan, Lei Zhang, Mingjing Li, Weiying Ma, Zhengkai Liu, ...
The canonical face recognition algorithm Eigenface and Fisherface are both based on one dimensional vector representation. However, with the high feature dimensions and the small training data, face...
