Face recognition using two-dimensional nonnegative principal component analysis
- Abstract: Peng Ma, Dan Yang, Yongxin Ge et al. Although two-dimensional principal component analysis (2DPCA) extracts image features directly from 2D image matrices rather than one dimensional vectors, 2DPCA is only based on the whole images to preserve total variances by maximizing the trace of feature covariance matrix. Thus, 2DPCA cannot extr ... [J. Electron. Imaging 21, 033011 (2012)] published Tue Aug 14, 2012.
