PEM-PCA: A Parallel Expectation-Maximization PCA Face Recognition Architecture

Principal component analysis or PCA has been traditionally used as one of the feature extraction techniques in face recognition systems yielding high accuracy when requiring a small number of features. However, the covariance matrix and eigenvalue decomposition stages cause high computational comple...
