lightweight domain-specific appearance embedding for Turkey re-identification in dense barn environments","https:\u002F\u002Fdoi.org\u002F10.1016\u002Fj.atech.2026.102549","Individual-level monitoring of poultry in commercial barns requires identity-consistent tracking, which in turn depends on appearance features that can discriminate between visually homogeneous animals. Generic appearance models used in trackers such as DeepSORT are trained on human re-identification data and transfer poorly to livestock, where individuals lack the distinctive clothing and texture cues that drive pedestrian re-identification. In this work we present a lightweight domain-specific Siamese feature extractor for turkey re-identification, designed through a systematic, ablation-driven refinement process and trained with a combined batch-hard triplet and identity-classification objective. The final architecture combines pre-activation residual blocks, squeeze-and-excitation channel attention, and a BNNeck embedding head, and contains only 714K parameters — approximately 3.9 × fewer than the 2.8M-parameter mars-small128 model used by default in DeepSORT. On an open-set evaluation of 16 unseen turkey identities, the proposed embedding raises ROC AUC from 0.890 to 0.943, classification accuracy from 0.849 to 0.911, and the distribution separability index from 1.14 to 1.71, while reducing model storage by 3.8 × and inference latency relative to the baseline. A t-SNE projection of the learned space shows tight, well-separated clusters for the majority of identities, with residual overlap confined to the most visually similar individuals. When integrated into a DeepSORT tracking pipeline and evaluated on three commercial turkey-barn video sequences, the domain-specific embedding yields consistent gains in identity-related tracking metrics (IDF1 81.3 → 83.2%, association accuracy 68.8 → 69.9%). The results demonstrate that careful, domain-specific architectural design can substantially improve re-identification of visually homogeneous animals while simultaneously reducing computational cost. Within the scope of this controlled evaluation, the compact embedding is therefore well suited to resource-constrained edge hardware for continuous precision-livestock monitoring; large-scale field validation remains future work.","商业禽舍中对个体家禽的监测需要身份一致的跟踪，这依赖于能够区分视觉上同质动物的外观特征。DeepSORT等跟踪器中使用的通用外观模型基于行人重识别数据训练，难以有效迁移至牲畜场景，因为个体缺乏驱动行人重识别的独特服装和纹理线索。本研究提出了一种轻量级、面向特定领域的Siamese特征提取器，用于火鸡重识别，通过系统性的消融驱动优化流程设计，并采用批量硬三元组与身份分类联合目标进行训练。最终架构结合了预激活残差块、挤压激励通道注意力及BNNeck嵌入头，仅含71.4万参数——约为DeepSORT默认使用的280万参数mars-small128模型的3.9分之一。在包含16个未见火鸡身份的开放集评估中，所提出的嵌入将ROC AUC从0.890提升至0.943，分类准确率从0.849提升至0.911，分布可分性指数从1.14提升至1.71，同时模型存储量减少3.8倍，推理延迟相对基线降低。学习空间的t-SNE投影显示，大多数身份形成紧密且分离良好的簇，残余重叠仅限于视觉上最相似的个体。当集成至DeepSORT跟踪流程并在三段商业火鸡禽舍视频序列上评估时，该领域特定嵌入在身份相关跟踪指标上取得一致提升（IDF1从81.3%提升至83.2%，关联准确率从68.8%提升至69.9%）。结果表明，精细的领域特定架构设计能显著改善视觉同质动物的重识别性能，同时降低计算成本。在本受控评估范围内，该紧凑嵌入非常适合资源受限的边缘硬件，用于持续精准畜牧业监测；大规模现场验证仍为未来工作方向。","Smart

facilitating the transition of traditional agriculture toward a sustainable, resource-efficient, and quality-driven development paradigm. However, Information asymmetry in the agricultural and livestock products market gives rise to the “lemons problem,” impeding the sustainable consumption of high-quality, differentiated products and undermining their ability to command premium pricing. With the development of the digital economy, short-video live streaming has emerged as a new driver for promoting the sustainable consumption of such products at premium prices. Drawing on servicescape theory, this study uses Inner Mongolia mutton as a representative case and constructs a structural equation model based on 402 valid questionnaires to examine the formation mechanism of consumers’ premium purchase intentions for specialty agricultural and livestock products in short-video live streaming. In addition, multi-group analysis is conducted to examine whether these mechanisms differ across consumers with different demographic characteristics. The results indicate that short-video live streaming effectively encourages consumers to purchase specialty agricultural and livestock products at premium prices through the dual pathways of “scene reconstruction–value upgrading” and “scene reconstruction–trust establishment.” Further, multi-group analysis reveals significant differences in consumers’ psychological responses and purchase intentions across demographic groups. This study provides a theoretical basis and practical insights for promoting the sustainable consumption of specialty agricultural and livestock products at premium prices, and thereby contribute to the long-term sustainability of the agricultural sector.","推进优质农产品和畜产品优质优价的市场实现，对于促进传统农业向可持续、资源节约型和品质驱动型发展范式转型至关重要。然而，农产品和畜产品市场中的信息不对称引发了“柠檬问题”，阻碍了优质差异化产品的可持续消费，并削弱了其实现优质优价的能力。随着数字经济的发展，短视频直播已成为促进此类产品优质优价可持续消费的新动力。本研究基于服务场景理论，以内蒙古羊肉为代表性案例，基于402份有效问卷构建结构方程模型，考察短视频直播中消费者对特色农产品和畜产品溢价购买意愿的形成机制。此外，通过多群组分析检验这些机制在不同人口统计特征消费者之间是否存在差异。结果表明，短视频直播通过“场景重构—价值升级”和“场景重构—信任建立”的双重路径，有效促进消费者以溢价购买特色农产品和畜产品。进一步的多群组分析揭示，不同人口统计群体消费者在心理反应和购买意愿方面存在显著差异。本研究为促进特色农产品和畜产品优质优价的可持续消费提供了理论基础和实践启示，进而有助于农业部门的长期可持续发展。","Frontiers
