First, for thinning target identification, a lightweight you only look once dilated dual-path network (YOLO-DDPNet) segmentation network was developed by integrating a DDPNet module into the YOLOv8 architecture. This network achieved a tobacco seedling segmentation accuracy of 98.7% (3.6% higher than YOLOv8n), enabling thinning target screening by comparing the segmentation mask areas of tobacco seedlings within a seedling hole. Second, for seedling growth point detection, the original C2f module in YOLOv8 was replaced with C3x while incorporating the SE attention mechanism and SPPCSPC multiscale feature fusion module to construct a lightweight YOLO-TGPD detection network. This network attained a growth point detection accuracy of 94.3% (8.2% higher than YOLOv8n). Notably, this study pioneered the synergistic use of segmentation and detection strategies to simultaneously complete thinning target screening and growth point detection.

Finally, a comparison between pure sandy soil and a sandy–clay mixture led to the final model, which also incorporates effective porosity.

Satellite-derived land-surface temperature data can be an essential input for detecting such a disease, as it plays a critical role in the pathogen’s development and spread. When combined with other environmental factors, such as humidity and leaf wetness, it serves as a key indicator of potential outbreaks. Vegetation and moisture indexes captured by the European Space Agency satellite Sentinel 2, have been used to analyze rice blast disease on a large scale. However, due to substantial geo-spatial and temporal variability, predicting disease occurrence remains a challenge. To address this gap, we propose a fusion of convolutional neural networks (CNN) and transformer-based models to reveal both local and global syndromes in images associated with the risk of rice blast disease. A novel multichannel attention mechanism within the CNN helps extract essential spectral information, where each RGB channel’s spatial intensity is leveraged to focus on critical details through multihead attention. The transformer network with dynamic tokenization and self-attention captures global information, enabling lightweight transformers to highlight discriminative global features. Dynamic tokenization selects tokens or patches based on attention factors, facilitating the extraction of important sequential information. The aggregated network output enhances the classification accuracy of leaf blast risk prediction while reducing computational complexity. The proposed approach outperforms existing models in spectral image analysis for predicting the spread of leaf blast disease.","PeriodicalId":100637,"journal":{"name":"IEEE Transactions on AgriFood Electronics","volume":"3 2","pages":"615-622"},"PeriodicalIF":0.0,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate detection of aphids in fields is a crucial step in implementing sustainable agricultural pest management. However, the tiny size of aphids and the complex image background present significant challenges for accurate identification and classification for in-field detection. In response to the challenges, this study proposes a lightweight real-time object detection model, Aphid-YOLO (A-YOLO), for in-field aphid identification and counting. Specifically, a tiny path aggregation network with C2f-CG modules is proposed to enhance the detection ability of tiny objects while maintaining a low computational cost through efficiently fusing multilayer features. For model training, a normalized Wasserstein distance loss function is adopted to address the optimization challenges caused by the tiny size of aphids. In addition, an optimized data augmentation method, Mosaic9, is introduced to enrich training samples and positive supervised signals for addressing the classification challenge of tiny aphids. To validate the effectiveness of A-YOLO, this study conducts comprehensive experiments on an aphid detection dataset with images collected by hand-held devices from a complex field environment. Experimental results demonstrate that A-YOLO achieves outstanding detection efficiency, with an mAP@0.5 of 83.4%, an mAP@0.5:0.95 of 33.7%, an inference speed of 72 FPS, and a model size of 30.6 MB. Compared to the YOLOv8m model employing traditional Mosaic data augmentation, the proposed method improves mAP@0.5 by 5.8%, mAP@0.5:0.95 by 2.7%, increases inference speed by 5 FPS, and reduces model size by 38.4% .","PeriodicalId":100637,"journal":{"name":"IEEE Transactions on AgriFood Electronics","volume":"3 2","pages":"605-614"},"PeriodicalIF":0.0,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in order to solve the problem of difficult detection of stem sticks in cut tobacco, a stem sticks detection algorithm in cut tobacco based on hyperspectral image technology combined with improved YOLOv8n is proposed. First, a principal component analysis method was used to process the hyperspectral image data to improve the differentiation between cut tobacco and stem sticks, and to construct the dataset. Second, the YOLOv8n algorithm was optimized to obtain the GMCM-YOLOv8n algorithm. Multiscale convolutional attention was introduced in the backbone network to capture detail information. Then, ghost convolution (GhostConv) was introduced to replace the regular convolution to simplify the network. M-BiFPN modules are proposed in neck networks as a way to improve the detection of small-sized stem sticks. The C2f module is also improved to obtain P-C2f with a view to reducing the model parameters and computational volume. Finally, the effectiveness of the GMCM-YOLOv8n algorithm is experimentally verified on self-constructed dataset. The results of the experiment showed that: the algorithm achieved a mean average precision of 93.9%, with parameters and floating point operations of 2.2 M and 6.2 G, respectively, and frames per second maintained at 73.5 fps.

Image-based approaches often struggle with early-stage detection, while sensor-based methods prone to reliability issues due to potential system failures. This study addresses these challenges by integrating complementary data of the Jamun (Syzygium cumini) plant from Internet of Things (IoT)-enabled sensors and mobile-captured images to develop a hybrid machine learning (ML) model for early and accurate plant disease detection. The proposed model combines a multilayer perceptron (MLP) for processing numerical sensor inputs—ambient temperature, soil temperature, relative humidity, soil moisture, and leaf wetness duration—and a convolutional neural network (CNN) for analyzing leaf images labeled as leaf spot, anthracnose, or healthy. Outputs from the MLP and CNN concatenated and processed through an additional MLP to classify plant health effectively. Optimized with hidden layer configurations of 8-16-32-8 for the sensor-data MLP, 16--32-64-128_32-8-4 for the image-data CNN, and 4-3 layers for the final MLP, the model achieves a loss of 1% and an accuracy of 95%, outperforming state-of-the-art methods, such as DenseNet201-support vector machines (SVM) (87.23%) and gray level co-occurrence matrix-SVM (90%).

CT scanning yields cross-sectional sequences that unveil insights into the internal structure of pore networks, which is crucial for understanding root–soil interactions. In this investigation, we explore the potential of employing a high-resolution amorphous selenium (a-Se) direct conversion detector coupled with complementary metal–oxide–semiconductor (CMOS) readouts for micro-CT scanning of soil matrices. This approach aims to visualize the aggregation status and pore network connectivity within intact soil. In addition, we compare the capabilities of the a-Se/CMOS detector with other commercially available detectors evaluating performance in terms of spatial resolution, noise levels, and overall imaging quality. The integration of a-Se’s intrinsic high spatial resolution with small-pixel CMOS readouts enables detailed visualization of soil aggregates in plant samples.
