Automatic group emotion recognition plays an important role in understanding complex human-human interaction. This paper introduces, Emolysis, a Python-based, standalone open-source group emotion analysis toolkit for use in different social situations upon getting consent from the users. Given any input video, Emolysis processes synchronized multimodal input and maps it to group level emotion, valence and arousal. Additionally, the toolkit supports major mobile and desktop platforms (Android, iOS, Windows). The Emolysis platform also comes with an intuitive graphical user interface that allows users to select different modalities and target persons for more fine-grained emotion analysis. Emolysis is freely available for academic research and encourages application developers to extend it to application specific environments on top of the existing system. We believe that the extension mechanism is quite straightforward. Our code models and interface are available at https://github.com/ControlNet/emolysis.

翻译：自动群体情绪识别在理解复杂人机交互中扮演着重要角色。本文介绍了Emolysis——一个基于Python的独立开源群体情绪分析工具包，可在获得用户同意后应用于不同社交场景。给定任意输入视频，Emolysis处理同步的多模态输入并将其映射至群体层面的情绪、效价与唤醒度。该工具包同时支持主流移动与桌面平台（Android、iOS、Windows）。Emolysis平台还配备了直观的图形用户界面，允许用户选择不同模态及目标人物以进行更细粒度的情绪分析。本工具包免费开放用于学术研究，并鼓励应用开发者在现有系统基础上将其扩展至特定应用环境。我们相信其扩展机制相当直观。代码模型与界面可通过https://github.com/ControlNet/emolysis获取。
