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,...
Face recognition plays an important vision task having many practical applications such as biometrics, video surveillance, image retrieval, and human computer interaction. Most recently facial expression recognition has been focused for biometric facial recognition system in various confidential and high secured operational areas. Information for biometric representation and recognition are ava...
Emotional expressions are the behaviors that communicate our emotional state or attitude to others. They expressed through verbal and non-verbal communication. Complex human behavior can be understood by studying physical features from multiple modalities; mainly facial, vocal gestures. Recently, spontaneous multi-modal emotion recognition has been extensively studied for analysis. In this pape...
Facial Expression is a key component in evaluating a person's feelings, intentions and characteristics. Facial Expression is an important part of human-computer interaction and has the potential to play an equal important role in humancomputer interaction. The aim of this paper is bring together two areas in which are Artificial Neural Network (ANN) and KNearest Neighbor (K-NN) applying for fac...
Facial motions convey personal characteristics and subtle emotional states. This paper presents a new framework to model facial motions of different people with multiple expression types from high resolution facial expression tracking data. We also provide a mechanism to animate subtle facial expressions based on video sequences. A conceptual motion manifold is used for a unified representation...
In this paper, we present an embedded system in which face recognition and facial expression recognition for Human-Robot Interaction are implemented. To detect face with a fast and reliable way, AdaBoost algorithm is used. Then, Principal Component Analysis is applied for recognizing the face. Gabor wavelets are combined with Enhanced Fisher Model for facial expression recognition. Performance ...
This article introduces recent advances in the machine analysis of facial expressions. It describes the problem space, surveys the problem domain and examines the state of the art. Two recent research topics are discussed with particular attention: analysis of facial dynamics and analysis of naturalistic (spontaneously displayed) facial behaviour. Scientific and engineering challenges in the fi...
Facial expression is one of the primary communication means of the human. However, realistic facial expression images are not used in popular communication tools on portable devices because of the difficulties in: 1) Acquisition; 2) Transference; 3) Display. In this paper, we propose a system tackling these problems to synthesize facial expression images from photographs for the devices with li...
This paper presents the methodology and performance of a statistical shape representation for automatic facial expression analysis in 3-D. The core of the method uses the statistical shape modelling technique with the deformable model-based surface matching process, which is capable of simulation and interpretation of 3-D human facial expressions. Using the proposed method, a 3-D face is repres...
Facial expression plays significant role for human beings to communicate their emotions. Automatic facial expression analysis is a flourishing area of research in computer science, and it is also still a challenge. This paper discusses the application of a natural network based facial expression recognition using fisherface. Back propagation neural network is used as a classifier for classifyin...
