基于改进SlowFast的家猫行为识别模型OA

A domestic cat behavior recognition model based on improved SlowFast

中文摘要英文摘要

家猫的行为模式可直接反映其生理和心理健康状态,准确识别家猫日常行为有助于及时发现宠物异常、提升宠物福利水平.现有动物行为识别方法多聚焦于畜牧动物,难以有效应对家猫行为动作幅度小、时序变化快、背景环境复杂的挑战.针对上述问题,提出了SMT-SlowFast 模型,该模型基于 SlowFast 框架,在 Slow 路径与 Fast 路径中协同引入时序移位模块(temporal shift module,TSM)与SEAM注意力模块(SE-SimAM attention module).TSM通过沿时间维度对部分通道特征进行前后移位,实现相邻帧信息的高效交互,增强对行为动态时序变化的建模能力;SEAM融合通道级注意力与神经元级重要性的三维权重,突出关键行为区域并有效抑制复杂背景干扰.构建了多场景家猫行为数据集(multi-scene domestic cat behavior dataset,MDCBD)对SMT-SlowFast 模型进行验证.实验结果表明:针对 8 类 行 为,SMT-SlowFast 模型准确率达到94.60%,优于多个基准模型,且对理毛、奔跑和行走等行为的识别性能提升尤为显著.该研究为非接触式家猫行为监测提供了高效、鲁棒的技术路径.

Domestic cats′ behavioral characteristics can directly reflect their physical and emotional wellness.Accurately recognizing their daily behaviors allows for early recognition of pet abnormalities and improves their well-being.Existing animal behavior recognition methods are mostly geared toward livestock and cannot accurately recognize domestic cat behaviors,for these behaviors are usually characterized by small motion amplitudes,quick temporal dynamics,and complex backgrounds.To address this issue,an SMT-SlowFast model was proposed,in which the temporal shift module(TSM)and the SE-SimAM(SEAM)attention module were collaboratively introduced into both the Slow and Fast pathways based on the SlowFast framework.Features of specific channels were shifted forward and backward by TSM along the temporal dimension,allowing for efficient interaction between adjacent frames and improving the modeling capability for dynamic behavioral changes over time;three-dimensional weight of channel-level attention and neuron-level importance were integrated by SEAM,resulting in highlighted key behavioral regions and effectively suppressed complex background interference.In order to validate the SMT-SlowFast model,the multi-scene domestic cat behavior dataset(MDCBD)was created.Experimental results show that,for the eight behaviors,the SMT-SlowFast model outperforms several baseline models,with an accuracy of 94.60%.Notably,SMT-SlowFast provides particularly substantial improvements in recognizing behaviors like grooming,running,and walking.This study provides an efficient and robust technical approach for non-contact monitoring of domestic cat behavior.
