An Analysis of Visual Faces Datasets

2016
This paper presents an analysis of datasets of images of human faces with annotated facial keypoints, which are important in human-machine interaction, and their comparison. Datasets are divided according to external conditions of the subject into two groups: datasets in laboratory conditions and in the wild data.

Face liveness detection through face structure analysis

International Journal of Applied Pattern Recognition, 2014
Liveness detection is a way to detect whether the person is live or not during submission of his/her biometric trait. It is mandatory in order to prevent face spoofing attacks. Therefore, in this paper, we proposed a robust face structure analysis mechanism to detect the liveness by exploiting face shape information.

Face-to-Face and Computer-Mediated Communities, A Comparative Analysis

The Information Society, 1999
In this article we combine the perspectives of sociology and computer science to compare face-to-face (f2f) and computer-mediated communications (CMC) from the viewpoint of their respective abilities to form and sustain communities. We also identify a third type of community-a hybrid-that is based on a combination of faceto-face (f2f) and CMC, or off ...

Neurologic analysis of face pain

Postgraduate Medicine, 1984
Analysis of face pain is predicated on knowledge of the structures of the face, head, and neck that may generate this sensation. Of particular importance in this process are historical data; characteristics of the pain, as elicited in history taking, should lead to the definition of recognized syndromes that may threaten a patient's survival or ...

Analysis of 3D Face Reconstruction

2009
This thesis investigates the long standing problem of 3D reconstruction from a single 2D face image. Face reconstruction from a single 2D face image is an ill posed problem involving estimation of the intrinsic and the extrinsic camera parameters, light parameters, shape parameters and the texture parameters.

Harmonic Analysis of the Human Face

Biometrics, 1965
Three-cycled Fourier equations are used in representing the frontal and lateral views of the human face. Fourier equations representing the general pattern of a group of individuals can also be obtained. The group pattern then represents the pattern characteristics common to all individuals.

Multilinear Discriminant Analysis for Face Recognition

IEEE Transactions on Image Processing, 2007
There is a growing interest in subspace learning techniques for face recognition; however, the excessive dimension of the data space often brings the algorithms into the curse of dimensionality dilemma. In this paper, we present a novel approach to solve the supervised dimensionality reduction problem by encoding an image object as a general tensor of ...

Face Recognition by Regularized Discriminant Analysis

IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2007
When the feature dimension is larger than the number of samples the small sample-size problem occurs. There is great concern about it within the face recognition community. We point out that optimizing the Fisher index in linear discriminant analysis does not necessarily give the best performance for a face recognition system.

Entropy in Biometric Face Template Analysis

2012
We will consider systems whose galleries contain more templates for each subject, and will explore the concept of representativeness of a biometric sample. This parameter varies from subject to subject, and is not a feature of the whole gallery. The gallery samples of certain subject might be too much similar, just because they are all of excellent ...
