📝 摘要(中文)
微表情(MEs)是揭示个体真实情感状态的细微非语言线索,其分析在医疗、刑事调查和人机交互等领域具有重要应用。然而,现有研究主要集中于单一视觉模态,忽视了其他生理模态所传递的丰富情感信息,导致微表情识别和检测性能远低于实际应用需求。为此,本文首次提出MMME数据集,支持面部动作信号、中央神经系统信号(EEG)和外周生理信号(PPG、RSP、SKT、EDA和ECG)的同步收集,建立了微表情神经机制研究和多模态融合分析的坚实基础。实验结果验证了数据集的可靠性,并显示将微表情与生理信号结合显著提升了识别和检测性能。
🔬 方法详解
问题定义:本文旨在解决现有微表情分析中单一视觉模态的局限性,缺乏对生理信号的综合利用,导致识别和检测性能不足的问题。
核心思路:通过构建MMME数据集,实现微表情与多种生理信号的同步收集,探索视觉特征与生理信号之间的跨模态关联机制,从而提升微表情的识别和检测性能。
技术框架:MMME数据集的构建包括三个主要模块:面部动作信号的捕捉、中央神经系统信号(EEG)的记录和外周生理信号(PPG、RSP、SKT、EDA和ECG)的同步采集,形成一个多模态融合的分析框架。
关键创新:MMME数据集是迄今为止最全面的微表情数据集,涵盖多种模态,突破了以往研究的单一模态限制,为微表情的神经机制研究提供了新的数据支持。

该研究的潜在应用领域包括医疗健康监测、心理状态评估、刑事调查中的情感分析以及人机交互中的情感识别等。通过多模态融合,能够更准确地捕捉和理解个体的情感状态,为相关领域提供更为有效的技术支持和解决方案。
📄 摘要(原文)
Micro-expressions (MEs) are subtle, fleeting nonverbal cues that reveal an individual's genuine emotional state. Their analysis has attracted considerable interest due to its promising applications in fields such as healthcare, criminal investigation, and human-computer interaction. However, existing ME research is limited to single visual modality, overlooking the rich emotional information conveyed by other physiological modalities, resulting in ME recognition and spotting performance far below practical application needs. Therefore, exploring the cross-modal association mechanism between ME visual features and physiological signals (PS), and developing a multimodal fusion framework, represents a pivotal step toward advancing ME analysis. This study introduces a novel ME dataset, MMME, which, for the first time, enables synchronized collection of facial action signals (MEs), central nervous system signals (EEG), and peripheral PS (PPG, RSP, SKT, EDA, and ECG). By overcoming the constraints of existing ME corpora, MMME comprises 634 MEs, 2,841 macro-expressions (MaEs), and 2,890 trials of synchronized multimodal PS, establishing a robust foundation for investigating ME neural mechanisms and conducting multimodal fusion-based analyses. Extensive experiments validate the dataset's reliability and provide benchmarks for ME analysis, demonstrating that integrating MEs with PS significantly enhances recognition and spotting performance. To the best of our knowledge, MMME is the most comprehensive ME dataset to date in terms of modality diversity. It provides critical data support for exploring the neural mechanisms of MEs and uncovering the visual-physiological synergistic effects, driving a paradigm shift in ME research from single-modality visual analysis to multimodal fusion. The dataset will be publicly available upon acceptance of this paper.
