摘要:

在过去的十年中,自动情感识别已经成为一个热门的研究课题。虽然基于面部表情或语音的作品比比皆是,但从肢体动作中识别情感仍然是一个较少探索的主题。我们提出了一个新的全面调查,希望能促进该领域的研究。我们首先介绍情感肢体动作,作为通常所说的“肢体语言”的一个组成部分,并评论性别差异和文化依赖等一般方面。然后,我们定义了一个完整的框架,自动情感身体姿态识别。本文介绍了人体检测技术,评述了RGB和3D环境下的静态和动态人体姿态估计方法。然后,我们评论了最近的文献相关的表示学习和情绪识别的图像的情绪表达的姿态。我们还讨论了多模态方法,结合语音或面部与身体姿势,以提高情感识别。虽然预处理方法(如人体检测和姿态估计)是目前成熟的技术,充分发展强大的大规模分析,我们表明,情感识别的标记数据的数量是稀缺的,没有明确定义的输出空间和表示是浅,主要是基于天真的几何表示。

英文摘要:

Automatic emotion recognition has become a trending research topic in the past decade. While works based on facial expressions or speech abound, recognizing affect from body gestures remains a less explored topic. We present a new comprehensive survey hoping to boost research in the field. We first introduce emotional body gestures as a component of what is commonly known as "body language" and comment general aspects as gender differences and culture dependence. We then define a complete framework for automatic emotional body gesture recognition. We introduce person detection and comment static and dynamic body pose estimation methods both in RGB and 3D. We then comment the recent literature related to representation learning and emotion recognition from images of emotionally expressive gestures. We also discuss multi-modal approaches that combine speech or face with body gestures for improved emotion recognition. While pre-processing methodologies (e.g. human detection and pose estimation) are nowadays mature technologies fully developed for robust large scale analysis, we show that for emotion recognition the quantity of labelled data is scarce, there is no agreement on clearly defined output spaces and the representations are shallow and largely based on naive geometrical representations.
