Development of a System for Automatic Facial Expression Analysis

Automatic Facial Expression Analysis

Facial expression analysis is an active area in human-computer interaction. Many techniques of facial expression analysis have been proposed that try to make the interaction tighter and more efficient. The essence of facial expression analysis is to recognize facial actions or to perceive human emotion through the changes of the face surface. Generally, there are three main steps in analyzing f...

Automatic facial expression analysis

Humans spend a large amount of their time interacting with computers of one type or another. However, computers are emotionally blind and indifferent to the affective states of their users. Human-computer interaction which does not consider emotions, ignores a whole channel of available information. Faces contain a large portion of our emotionally expressive behaviour. We use facial expressions...

Automatic 3D Facial Expression Analysis in Videos

We introduce a novel framework for automatic 3D facial expression analysis in videos. Preliminary results demonstrate editing facial expression with facial expression recognition. We first build a 3D expression database to learn the expression space of a human face. The real-time 3D video data were captured by a camera/projector scanning system. From this database, we extract the geometry defor...

Automatic Facial Expression Analysis and Emotional Classification

In this thesis, a system for automatic facial expression analysis was designed and implemented. This system includes a monocular 3d head pose tracker to handle rigid movements, feature extraction based on Gabor wavelets and gradient orientation histograms, and a SVM classifier. Further more, a database with video sequences of acted and natural facial expression was compiled and tests were done,...
