The analysis of human emotions through facial expression examination is crucial for advancing natural and responsive human-computer interactions. This study introduces a robust facial expression recognition (FER) system utilizing machine learning methodologies, incorporating Local Binary Patterns (LBP) for feature extraction and Support Vector Machines (SVM) for classification. The system is engineered to identify seven fundamental human emotions: Anger, Contempt, Disgust, Fear, Happiness, Sadness, and Surprise. LBP is utilized to efficiently capture texture-based facial features, proving particularly effective in distinguishing subtle variations in expressions among different individuals. These extracted features are subsequently classified using an SVM model, renowned for its strong generalization capabilities in high-dimensional spaces. The system's performance is assessed using two benchmark datasets: COHN-KANADE and JAFFE, both of which are widely acknowledged in facial emotion research. Experimental results indicate that the proposed method surpasses conventional techniques in terms of recognition accuracy and processing speed. Its low computational complexity further enhances its applicability for real-time applications in domains such as emotion-aware systems, security, healthcare, and intelligent tutoring. This research underscores the potential of integrating texture descriptors with powerful classifiers to develop efficient, scalable, and highly accurate FER systems that can contribute to more empathetic and adaptive machine responses.

摘要

The analysis of human emotions through facial expression examination is crucial for advancing natural and responsive human-computer interactions. This study introduces a robust facial expression recognition (FER) system utilizing machine learning methodologies, incorporating Local Binary Patterns (LBP) for feature extraction and Support Vector Machines (SVM) for classification. The system is engineered to identify seven fundamental human emotions: Anger, Contempt, Disgust, Fear, Happiness, Sadness, and Surprise. LBP is utilized to efficiently capture texture-based facial features, proving particularly effective in distinguishing subtle variations in expressions among different individuals. These extracted features are subsequently classified using an SVM model, renowned for its strong generalization capabilities in high-dimensional spaces. The system's performance is assessed using two benchmark datasets: COHN-KANADE and JAFFE, both of which are widely acknowledged in facial emotion research. Experimental results indicate that the proposed method surpasses conventional techniques in terms of recognition accuracy and processing speed. Its low computational complexity further enhances its applicability for real-time applications in domains such as emotion-aware systems, security, healthcare, and intelligent tutoring. This research underscores the potential of integrating texture descriptors with powerful classifiers to develop efficient, scalable, and highly accurate FER systems that can contribute to more empathetic and adaptive machine responses.
