Face Detection and Verification using Local Binary Patterns

Yann Rodriguez

This thesis proposes a robust Automatic Face Verification (AFV) system using Local Binary Patterns (LBP). AFV is mainly composed of two modules: Face Detection (FD) and Face Verification (FV). The purpose of FD is to determine whether there are any face in ...

Local Binary Patterns as an Image Preprocessing for Face Authentication

Sébastien Marcel, Guillaume Heusch, Yann Rodriguez

One of the major problem in face authentication systems is to deal with variations in illumination. In a \mbox{realistic} scenario, it is very likely that the lighting conditions of the probe image does not correspond to those of the gallery image, hence t ...

Active Shape Models Using Local Binary Patterns

Sébastien Marcel, Jean Keomany

This report addresses the problem of locating facial features in images of frontal faces taken under different lighting conditions. The well-known Active Shape Model method proposed by Cootes {\it et al.} is extended in order to improve its robustness to i ...

Robust-to-Illumination Face Localisation using Active Shape Models and Local Binary Patterns

Sébastien Marcel, Yann Rodriguez, Jean Keomany

This paper addresses the problem of locating facial features in images of frontal faces taken under different lighting conditions. The well-known Active Shape Model method proposed by Cootes {\it et al.} is extended to improve its robustness to illuminatio ...

Face Authentication Using Adapted Local Binary Pattern Histograms

Sébastien Marcel, Yann Rodriguez

In this paper, we propose a novel generative approach for face authentication, based on a Local Binary Pattern (LBP) description of the face. A generic face model is considered as a collection of LBP-histograms. Then, a client-specific model is obtained by ...

Multimedia event modelling and recognition

Mark Barnard

The recognition of events in multimedia data is a challenging area of research. The growth in the amount of multimedia data being produced and stored increases the need for systems capable of automatically analysing this data. This analysis can aid in effi ...

Lighting Normalization Algorithms for Face Verification

Sébastien Marcel, Guillaume Heusch

In this report, we address the problem of face verification across illumination, since it has been identified as one of the major factor degrading the performance of face recognition systems. First, a brief overview of face recognition together with its ma ...
