人脸表情识别作为情感计算的一个研究方向,构成了情感理解的基础,是实现人机交互智能的前提。人脸表情的极度细腻化消耗了大量的计算时间,影响了人机交互的时效性和体验感,所以人脸表情特征提取成为人脸表情识别的重要研究课题。总结了国内外近五年的人脸表情识别的稳固框架和新进展,主要针对人脸表情特征提取和表情分类方法进行了归纳,详细介绍了这两方面的主要算法及改进,并分析比较了各种算法的优势与不足。通过对国内外人脸表情识别应用中实际问题进行研究,给出了人脸表情识别方面仍然存在的挑战及不足。
人臉錶情識彆作為情感計算的一箇研究方嚮,構成瞭情感理解的基礎,是實現人機交互智能的前提。人臉錶情的極度細膩化消耗瞭大量的計算時間,影響瞭人機交互的時效性和體驗感,所以人臉錶情特徵提取成為人臉錶情識彆的重要研究課題。總結瞭國內外近五年的人臉錶情識彆的穩固框架和新進展,主要針對人臉錶情特徵提取和錶情分類方法進行瞭歸納,詳細介紹瞭這兩方麵的主要算法及改進,併分析比較瞭各種算法的優勢與不足。通過對國內外人臉錶情識彆應用中實際問題進行研究,給齣瞭人臉錶情識彆方麵仍然存在的挑戰及不足。

As a research direction of the affective computing, facial expression recognition which constitutes the basis of emotion understanding, is the premise to complete human-computer interaction intelligent. Facial expression is so exqui-site that it consumes a large amount of computation time and influences the timeliness and experience feeling from human-computer interaction intelligent. Consequently, facial feature extraction has become an important research topic in the area of facial expression recognition. The progress and stable framework for facial expression recognition in recent five years are generalized, a serial of algorithms applied in feature extraction and expression classification are summarized, Then, the main algorithms and their improvement are described in detail, and advantages and disadvantages among in different algorithms are analyzed and compared. In the same time, comparison with the other algorithms is also introduced. The challenges and shortcomings are pointed out by the research of practical problems in facial expression recognition application.
