Abstract
Face verification systems reach good performance on ideal environmental conditions. Conversely, they are very sensitive to non-controlled environments. This work proposes the class-Modular Image Principal Component Analysis (cMIMPCA) algorithm for face verification. It extracts local and global information of the user faces aiming to reduce the effects caused by illumination, facial expression and head pose changes. Experimental results performed over three well-known face databases showed that cMIMPCA obtains promising results for the face verification task.

A novel partition selection method for modular face recognition approaches on occlusion problem

TL;DR: In this paper, the authors proposed a new method to detect and to use the non-occluded parts of face image for modular face recognition approaches, where the occlusion of a partition is decided using the combination of three coefficients which can be easily derived: (i) image entropy, (ii) image correlation, (iii) root-mean-square error.

Two-dimensional PCA: a new approach to appearance-based face representation and recognition

TL;DR: A new technique coined two-dimensional principal component analysis (2DPCA) is developed for image representation that is based on 2D image matrices rather than 1D vectors so the image matrix does not need to be transformed into a vector prior to feature extraction.
