چکیده

In this paper, we present an approach that unifies sub-space feature extraction and support vector classification for face recognition. Linear discriminant, independent component and principal component analyses are used for dimensionality reduction prior to introducing feature vectors to a support vector machine. The performance of the developed methods in reducing classification error and providing better generalization for high dimensional face recognition application is demonstrated.

Automatic Face Recognition via Local Directional Patterns

Automatic facial recognition has many potential applications in different areas of humancomputer interaction. However, they are not yet fully realized due to the lack of an effectivefacial feature descriptor. In this paper, we present a new appearance based feature descriptor,the local directional pattern (LDP), to represent facial geometry and analyze its performance inrecognition. An LDP feat...

Euclidean & Geodesic Distance between a Facial Feature Points in Two-Dimensional Face Recognition System

In this paper, we present two feature extraction methods for two-dimensional face recognition. Our approaches are based on facial feature points detection then compute the Euclidean Distance between all pairs of this points for a first method (ED-FFP) and Geodesic Distance in the second approach (GD-FFP). These measures are employed as inputs to a commonly used classification techniques such as...

Discriminant Gaborfaces and Support Vector Machines Classifier for Face Recognition

Feature extraction, discriminant analysis, and classification rule are three crucial issues for face recognition. This paper presents one method, named GaborfaceSVM, to handle three issues together. For feature extraction, we utilize the Gabor wavelet transform on grey face image to extract Gaborfaces. A Modified Enhanced Fisher Discriminant model is used to reinforce discriminant power of Gabo...

A Comparison of Face Detection Algorithms in Visible and Thermal Spectrums

Face Detection is the first step of facial recognition algorithms and has been widely researched in the visible spectrum. Current research has shown that thermal facial recognition is as accurate as the visible spectrum recognition algorithms. This paper presents three face detection algorithms in both long-wavelength infrared (LWIR) images and visible spectrum images. The paper compares the Vi...

Multi-view Gender Classification Using Local Binary Patterns and Support Vector Machines

In this paper, we present a novel approach to multi-view gender classification considering both shape and texture information to represent facial image. The face area is divided into small regions, from which local binary pattern(LBP) histograms are extracted and concatenated into a single vector efficiently representing the facial image. The classification is performed by using support vector ...
