Array of Multilayer Perceptrons with No-class Resampling Training for Face Recognition

D. Capello, C. Martínez, D. Milone, G. Stegmayer
2010 Inteligencia Artificial  
Once a face is located in an image, it has to be represented through a feature extraction process, for later performing a proper face classification task.  ...  In the classification phase, an input face is projected to the obtained eigenspace and classified by an appropriate classifier.  ...  In this way, if we deal with aproximately similar images of faces, they will be located in a small region of the space.  ...

Face recognition using the nearest feature line method

S.Z. Li, Juwei Lu
1999 IEEE Transactions on Neural Networks  
In this paper, we propose a novel classification method, called the nearest feature line (NFL), for face recognition.  ...  With a combined face database, the NFL error rate is about 43.7-65.4% of that of the standard eigenface method.  ...  In a feature space, which is an eigenface space in this study, the NFL method uses a linear model to interpolate and extrapolate each pair of prototype feature points belonging to the same class.  ...

Eigenfaces vs. Fisherfaces: recognition using class specific linear projection

P.N. Belhumeur, J.P. Hespanha, D.J. Kriegman
1997 IEEE Transactions on Pattern Analysis and Machine Intelligence  
Rather than explicitly modeling this deviation, we linearly project the image into a subspace in a manner which discounts those regions of the face with large deviation.  ...  We take advantage of the observation that the images of a particular face, under varying illumination but fixed pose, lie in a 3D linear subspace of the high dimensional image space-if the face is a Lambertian  ...  First, due to selfshadowing, specularities, and facial expressions, some regions in images of the face have variability that does not agree with the linear subspace model.  ...
