Abstract: With the development of artificial intelligence technology, facial expression recognition can extract expression states from images or videos to recognize the mental emotions of human beings, achieving a better human-computer interaction effect. However, there are many methods only focusing on facial expression recognition without occlusion, which is not applicable to objective and complex scenarios and greatly limits the practicality of the algorithm. In recent years, aiming at different types of occlusion such as illumination occlusion, low resolution occlusion, pose variations, and physical occlusion, researchers have proposed various new methods to solve these problems. The survey introduces the core ideas of relevant methods, and conducts a comparison analysis about these methods, meanwhile looks forward to future research and development.

摘要: 随着人工智能技术的发展,人脸表情识别可以从图像或视频中抽取表情状态,识别对象心理情绪,从而达到更好的人机交互效果。然而多数方法只关注正面无遮挡的人脸表情识别,并不能适用于客观复杂的场景,极大地限制了算法的实用性。近几年,针对光照遮挡、噪声遮挡、姿态遮挡、实物遮挡等不同类型的遮挡,研究者们提出了各种新方法来挑战人脸部分遮挡下的表情识别,综述了这些方法的主要原理并进行了对比分析,同时对未来的研究和发展方向进行了展望。
