The aim of research• The research aims to design automatic system

to distinguish and read facial expressions ( i.e., happy, surprise, anger, sadness, fear, and disgust ).

• By use of smart computer programming for design and implementation of the proposed system.

The goal of the system design

Introduction• To make Human Computer Interaction (HCI)

more natural and friendly, it would be beneficial to give computers the ability to recognize situations the same way a human does.

• Over the last years, face recognition and automatic analysis of facial expressions has one of the most challenging research areas in the field of Computer vision and has received a special importance.

Introduction& Previous Works

• In recent years, a lot of work has been done on the affective recognition of expressions which holds the major key in the human-machine interaction.

• In 1872. The first suggestion of expression of emotions as universal was given by Charles Darwin in his contriving work build from his theory of evolution.

Introduction& Previous Works

• In 1971. The psychologist Ekman and Friesen showed in their cross culture studies that the six emotions .

• Several techniques have emerged in order to improve the efficiency of the recognition by addressing problems in face detection and extraction features in recognizing expressions.

Importance of research and its Applications

• Facial Expression recognition is an important technique and has drawn the attention of many researchers due to its varying applications such as security systems, medical systems, entertainment.

Importance of research and its Applications

• Such as Human Computer Interaction (HCI), Emotion analysis, Psychological area, virtual reality , video-conferencing, indexing and retrieval of image and video database, image understanding and synthetic face animation.

Physically analysis

• The movement of facial muscles areas

Challenges

• A human can detect face and recognition on facial expressions without effort , but for a machine and in Computer Vision it is very difficult . Why… ?

Challenges

• The main challenges in automatic affect recognition :

• Head-pose variations.• illumination variations.• Registration errors. • Occlusions.

Basic Structure of Facial Expression analysis

Generic facial expression analysis framework

The proposed system

• We are trying to design a system able to identify for basic 6 facial Expression efficient and accurate depending on the improvement in the extraction of features which represents the core of the system .

• programming language “MatLab R2013a” Or newer

Conclusion

• The objective of this PPT is to show a clean survey on the structure of analyzing the facial expression . The steps involved in expression analysis like face acquisition, feature extraction and expression classification had been discussed.

• In addition to some of the challenges facing research in general.
