STS-NET：基于卫星影像时序的自监督作物胁迫检测网络
自监督3D-CAE用于卫星影像时序作物胁迫检测，方法新颖，数据真实，精度高，但论文仅5页，且发布于一周前，时效性较低。
研究提出基于自监督3D卷积自编码器（3D-CAE）的时空胁迫网络STS-NET，利用Planetscope高分辨率影像的NDVI、GNDVI、RECI和NDRE四种植被指数进行作物胁迫检测。模型在Barnala时空（BSPT）数据集训练，并在印度北方邦Lakhimpur-Kheri地区2.5英亩甘蔗试验田的真实数据集（一年期）上评估。STS-NET在水胁迫检测上达到97.98%精度、氮胁迫85.08%精度、复合胁迫83.47%精度。结果表明该网络能以最少标注数据有效检测甘蔗作物胁迫，并可作为简单模型的稳健特征提取器。
Abstract:Early and accurate detection of crop stress is essential to improve agricultural productivity and ensure global food security. However, collecting a large labeled crop stress dataset is a challenging task. To address this challenge, we introduce a novel spatial-temporal stress network (STS-NET), built on a self-supervised 3D-convolutional autoencoder (3D-CAE), designed to utilize Satellite Image Time Series (SITS) data for crop stress detection. STS-NET exploits four vegetation indices: Normalized Difference Vegetation Index (NDVI), Normalized Difference Vegetation Index (GNDVI), Red-Edge Chlorophyll Index (RECI) and Normalized Difference Red-Edge Index (NDRE) obtained from high resolution Planetscope imagery to capture spatiotemporal stress patterns. The model is trained on our BSPT (Barnala Spatial-Temporal) dataset and evaluated on a real-world sugarcane dataset collected over a year from a 2.5-acre test plot located in Lakhimpur-Kheri (LK) district in Uttar Pradesh in India. STS-NET achieved a precision of 97. 98% for water stress, 85.08% for nitrogen stress, and 83.47% for combined stress. The results demonstrate the potential of STS-NET in effectively detecting stress in sugarcane crops with minimal reliance on labeled data. Furthermore, STS-NET can serve as a robust feature extractor for simpler models.
