摘要:

在我们的日常生活和社会交往中,我们经常试图感知人们的情绪状态。在为机器提供类似的情感识别能力方面,已经有很多研究。从计算机视觉的角度来看,以前的大部分努力都集中在分析面部表情上,在某些情况下,还包括身体姿势。其中一些方法在特定环境中效果非常好。然而,它们的性能在自然、不受约束的环境中受到限制。心理学研究表明,除了面部表情和身体姿势之外,场景背景还为我们感知人们的情绪提供了重要信息。然而,用于自动情感识别的上下文的处理尚未被深入探索,部分原因是缺乏适当的数据。在本文中,我们提出了EMOTIC,一个数据集的图像的人在一组不同的自然情况下,他们的明显的情绪注释。EMOTIC数据集结合了两种不同类型的情绪表示:(1)一组26个离散类别,以及(2)连续维度效价,唤醒和支配。我们还提出了一个详细的数据集的统计和算法分析以及注释者的协议分析。使用EMOTIC数据集,我们训练不同的CNN模型进行情感识别,将包含人的限界框的信息与从场景中提取的上下文信息相结合。我们的研究结果表明,场景上下文提供了重要的信息,自动识别情绪状态,并激励在这个方向上进一步的研究。数据集和代码是开源的,可在https://github.com/rkosti/emotic上获得,同行评审的已发表文章链接:https://ieeexplore.ieee.org/document/8713881

英文摘要:

In our everyday lives and social interactions we often try to perceive the emotional states of people. There has been a lot of research in providing machines with a similar capacity of recognizing emotions. From a computer vision perspective, most of the previous efforts have been focusing in analyzing the facial expressions and, in some cases, also the body pose. Some of these methods work remarkably well in specific settings. However, their performance is limited in natural, unconstrained environments. Psychological studies show that the scene context, in addition to facial expression and body pose, provides important information to our perception of people's emotions. However, the processing of the context for automatic emotion recognition has not been explored in depth, partly due to the lack of proper data. In this paper we present EMOTIC, a dataset of images of people in a diverse set of natural situations, annotated with their apparent emotion. The EMOTIC dataset combines two different types of emotion representation: (1) a set of 26 discrete categories, and (2) the continuous dimensions Valence, Arousal, and Dominance. We also present a detailed statistical and algorithmic analysis of the dataset along with annotators' agreement analysis. Using the EMOTIC dataset we train different CNN models for emotion recognition, combining the information of the bounding box containing the person with the contextual information extracted from the scene. Our results show how scene context provides important information to automatically recognize emotional states and motivate further research in this direction.
