DISFA(Denver Intensity of Spontaneous Facial Action)

DISFA的全称是Denver Intensity of自发面部动作，是一个面部表情动作数据集。数据集由27个视频组成，每个视频4,844帧，总共130,788张图像。此数据集使用不同强度级别的动作单位进行注释。
DISFA数据集是从在面部表情识别领域流行的更广泛的数据库中剔除的，并且包含更多的笑脸数据 (即: 动作单元12)。此数据集中的smiley动作单元集包含30,792图像。此数据集中的82,176图像被设置为动作单元集，而48,612图像被设置为无动作单元集。

DISFA stands for Denver Intensity of Spontaneous Facial Action, which is a facial expression action dataset. The dataset consists of 27 videos, each with 4,844 frames, totaling 130,788 images. This dataset is annotated with action units of different intensity levels.
The DISFA dataset is curated from a broader database that is widely used in the field of facial expression recognition, and it includes more smiling face data (i.e., Action Unit 12). The smiley action unit set in this dataset contains 30,792 images. A total of 82,176 images in this dataset are assigned to the action unit set, while 48,612 images are assigned to the no-action-unit set.
