摘　　要：传统的人脸表情识别方法主要针对实验室环境下的基本表情,难以应对现实场景中人类微妙和复杂的表情变化,并且目前自然环境人脸表情识别数据集普遍缺乏足够的训练数据。针对该问题,利用实验室环境下的数据库样本,提出以标签引导的生成对抗网络表情识别域适应方法。将情感标签作为辅助条件,训练生成对抗网络的生成模型,把实验室环境的数据库样本转化为类似自然环境数据库的样本,以扩充自然环境数据库,同时基于扩充的数据库样本训练基本分类器VGG、Resnet等,从而学习自然环境的数据库的情感特征。在RAF_DB等自然环境人脸表情数据库上的实验结果表明,与Boosting-POOF和PixelDA方法相比,该方法扩充得到的数据库可使人脸表情识别率取得6%~9%的提升。In Facial Expression Recognition(FER),sufficient training samples have significant influence on recognition results.To address insufficient database samples in natural environment,this paper proposes a Label-guided Domain Adaption method in Generative Adversarial Network(LDAGAN)for FER by using laboratory environment database samples.This method adopts the generation model of GAN and takes emotional labels as auxiliary condition.Then the method uses the laboratory environment database samples to generate samples similar to those of natural environment database,so as to build a bridge between laboratory environment database and natural environment database,enlarging the natural environment database.The samples assist in learning the emotional features of the natural environment database.Experimental results on the facial expression database of natural environment such as RAF_DB show that the proposed method achieves an improvement of 6%to 9%in FER accuracy compared with Boosting-POOF and PixelDA methods.
