An Improved EMD-Based Dissimilarity Metric for Unsupervised Linear Subspace Learning
We investigate a novel way of robust face image feature extraction by adopting the methods based on Unsupervised Linear Subspace Learning to extract a small number of good features. Firstly, the face image is divided into blocks with the specified size, and then we propose and extract pooled Histogr...
