摘要:

【目的】 针对现有基于视频的抑郁检测方法计算开销过高的问题,本文提出了一种以兼顾预测精度与计算开销为目的的多尺度时间差分网络。【方法】 本文通过关键帧采样块定位表情突变区间并选取关键帧,在减少数据冗余的同时保留更多可用特征,通过时间差分块实现从短期到长期的层次化动态建模,通过时空融合块构建混合序列以对齐时空特征,并结合伪3D卷积实现时空信息的高效融合,为网络提供更全面的抑郁线索。【结果】 在两个公共数据集上进行相关实验,所设计的多尺度时间差分网络参数量仅为1.03M,浮点运算次数低至1.97 GFLOPs,在MAE和RMSE两个指标上也与其它先进抑郁水平评估方法保持极具竞争力的性能。【结论】 实验表明,本文提出的方法在极大地降低计算复杂度的同时很好地维持了精度,为抑郁水平任务提供了一种新思路。

Abstract:

[Objective] To address the high computational overhead in existing video-based depression assessment methods, this study proposes a Multi-scale Temporal Difference Network (MTDN) designed to balance prediction accuracy and computational efficiency. [Methods] The framework integrates three novel components: The Key Frame Sampling Block computes temporal differences between adjacent frames to quantify inter-frame variations, while a threshold-based binarization strategy identifies expression-change intervals and selects salient frames to reduce redundancy. The Temporal Difference Block, composed of long-term and short-term Dynamic Modeling Submodules, employs bidirectional differencing combined with multi-scale feature alignment to capture dynamics from micro-expressions to sustained emotional shifts. Additionally, the Spatial-Temporal Fusion Block constructs mixed sequences and applies Pseudo-3D convolution to align spatial and temporal feature maps, integrating spatiotemporal information critical for detecting depression cues. [Results] Experiments on two datasets demonstrate that MTDN achieves state-of-the-art efficiency with only 1.03M parameters and 1.97 GFLOPs. It also achieves highly competitive performance compared with advanced depression assessment methods in terms of MAE and RMSE. [Conclusions] This study establishes a new trade-off frontier for depression assessment, enabling deployment on resource-constrained devices without sacrificing diagnostic accuracy. This approach provides actionable insights for developing lightweight clinical decision support systems.
