- 3. Out Line • The aim of research • Introduction • History (Introduction & Previous Works) • Importance of research and its Applications • Physically analysis • Challenges • Related works • Basic Structure of Facial Expression analysis • The proposed system • Conclusion • References
- 4. 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.
- 5. The goal of the system design
- 6. 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.
- 7. 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.
- 8. 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.
- 9. 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.
- 10. 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.
- 11. Physically analysis • The movement of facial muscles areas
- 12. 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… ?
- 13. Challenges • The main challenges in automatic affect recognition : • Head-pose variations. • illumination variations. • Registration errors. • Occlusions.
