Protocols such as the Facial Action Coding System (FACS), a method for measuring facial behaviors developed by Paul Ekman, Wallace Friesen, and Joseph Hager, identify specific changes to facial expressions that occur with muscular contractions and quantify how the contraction of each facial muscle (singly and in combination with other muscles) changes the appearance of the face. Observed changes in the appearance of the face are associated with the action of muscles that produce them to create a reliable means for determining the category or categories in which each facial behavior belongs. FACS observations are quantified in measurement units known as Action Units (AUs). [...] Using FACS, an observed facial expression or action is decomposed into the specific AUs that produced the movement. A facial expression is thereby given a score that includes the list of AUs that produced it.
近年来，深度学习算法已应用于视觉对象识别、人脸验证和检测、图像分类等诸多问题，取得了最先进的效果。其中基于面部动作编码系统使用一系列特定的面部局部动作，称为动作单元，用来对面部表情进行编码。这些动作单元可以从基于几何图形的特性或从脸部图像中提取的外观特征图来识别，最近的基于面部表情的情感识别的工作使用卷积神经网络来识别情绪和动作单元。
