FEAFA+

FEAFA+是由中国科学院大学工程科学学院创建的一个扩展的面部表情分析和3D面部动画数据集。该数据集包含150个视频序列，总计230,184帧，这些帧被手动标注了24个重新定义的面部动作单元（AU）的浮点强度值。数据集结合了FEAFA和重新标注的DISFA数据库，旨在提供更丰富的面部表情数据，支持表情转移和面部动画等领域的研究。FEAFA+不仅数据量大，而且包含了多民族和多代人的表情变化，既有实验室记录的，也有在自然环境中记录的，为面部表情分析提供了宝贵的资源。

FEAFA+ is an extended facial expression analysis and 3D facial animation dataset created by the School of Engineering Science, University of Chinese Academy of Sciences. This dataset includes 150 video sequences totaling 230,184 frames, which have been manually annotated with floating-point intensity values for 24 redefined facial action units (AUs). By combining the original FEAFA dataset and the re-annotated DISFA database, it aims to provide richer facial expression data to support research in fields such as expression transfer and facial animation. Apart from its large scale, FEAFA+ covers facial expression variations across multiple ethnic groups and generations, with data recorded both in laboratory settings and natural environments, making it a valuable resource for facial expression analysis research.
