Additionally, they can harbor pests that reduce crop yields. In traditional agriculture, weed control is based on applying pesticides throughout the agricultural field, resulting in soil damage, environmental contamination, damage to farm products, and risks to human health. Precision agriculture (PA) has evolved in recent years thanks to sensors, hardware, software, and innovations in unmanned aerial vehicle (UAV) systems. These systems aim to improve the localized application of chemicals in weed control by using advanced image analysis techniques, computer vision, deep learning (DL), and geo-positioning (GPS) to detect and recognize weeds. This subsequently facilitates the implementation of specific control mechanisms in real environments. Recently, automatic weed detection techniques have been developed using UAV imagery. However, these face a significant challenge due to the morphological similarities between weeds and crops, such as color, shape, and texture, which makes their practical and effective differentiation and implementation difficult. This paper presents a systematic literature review (SLR) based on 77 recent and relevant studies on weed detection and classification in UAV imagery using DL architectures. The analysis focuses on key aspects such as using UAVs and sensors, image acquisition and processing, DL architecture, and evaluation metrics. The review covers publications from 2017 to June 2024 from WoS, Scopus, ScienceDirect, SpringerLink, and IEEE Xplore databases. The results allowed the identification of various limitations, trends, gaps, and opportunities for future research. In general, there is a predominant use of multirotor UAVs, particularly the DJI Phantom with RGB sensors, showing a trend towards the integration of multiple sensors (multispectral, LiDAR) operating at heights of around 10 meters, providing good spatial coverage in data acquisition. Likewise, the rapid development of deep learning architectures has driven CNN models such as ResNet for classification, YOLO for detection, U-Net for semantic segmentation, and Mask R-CNN for weed instance segmentation, with a tendency towards new Transformer-based and hybrid architectures. The most common metrics used to evaluate these models include precision, recall, F1-Score, and mAP.</div></div>","PeriodicalId":74813,"journal":{"name":"Smart agricultural technology","volume":"12 ","pages":"Article 101147"},"PeriodicalIF":6.3,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144570502","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}

Traditional methods for counting and yield estimation are time-consuming and demand significant physical effort, presenting substantial challenges for farmers. The use of drones and artificial intelligence, particularly deep learning, has transformed agricultural monitoring, enabling more accurate and rapid analyses. In this study, we introduce an advanced method for detecting tree crowns, focusing on olive trees in farm environments. Our approach is based on an innovative architecture that incorporates a Cross Stage Partial Network (CSPNet) combined with a Feature Pyramid Network (FPN) and Path Aggregation Network (PAN), augmented by DropBlock regularization. Our architecture is tailored for multi-scale object detection from UAV-captured imagery, addressing issues such as small object detection, complex backgrounds, object rotation, scale variations, and category imbalances in both simple imagery and high-resolution orthophotos. These orthophotos are produced by stitching together multiple high-quality images we captured from various angles and altitudes to create a comprehensive and detailed view of the orchard. Our methodology includes splitting images into different sizes (1 × 1, 3 × 3, 6 × 6, and 9 × 9) to enhance analysis and improve detection performance at various scales. This comprehensive approach has enabled us to conduct an in-depth analysis of olive trees, classified into small, medium, and large sizes. The results demonstrate the robustness of our method in addressing common object detection challenges in agricultural contexts, achieving a precision of 92.47 %, recall of 91.40 %, F1-score of 91.93 %, [email protected] of 94.00 %, and mAP@[0.5:0.95] of 87.00 %.

This study presents a novel approach combining advanced image segmentation and classification techniques to detect calcium deficiency in lettuce during its growth stages under colored LED lighting. Early detection of nutrient deficiencies is crucial for timely intervention and efficient nutrient management. This experiment involved growing butterhead lettuce plants under a Deep-Water Culture (DWC) system with controlled calcium treatments. Preprocessing techniques, including Contrast Limited Adaptive Histogram Equalization (CLAHE) and Red Color Correction (RCC), were applied to enhance quality and consistency and augmented to improve model generalization. Our methodology employed a two-stage process that allowed us to leverage the strengths of specialized models. First, lettuce leaves were segmented from the background using state-of-the-art models, including U-Net, U-Net++, Recurrent U-Net, and Inception U-Net. U-Net++ demonstrated the highest segmentation accuracy (98.56 %) with robust generalization compared to the other models. Segmentation isolates the region of interest and removes background noise, enabling the classifier to focus more effectively on disease-related features. Deep learning classification models, such as ResNet and EfficientNet, were applied in the second stage to detect calcium deficiency from the segmented images. EfficientNetB2 emerged as the most reliable classifier, achieving an accuracy of 91.51 % on the RCC dataset, while Resnet50 achieved a comparable accuracy of 91.18 % on the same dataset.

While plant physiology research has progressed, there remains a gap in applying sap flow sensor data to these species. In this study, the predictive capabilities of Recurrent Neural Network (RNN) architectures—LSTM, GRU, BiLSTM, and LRCN—are explored for sap flow estimation in tomato plants using stem diameter variations as the sole input. Unlike existing studies that rely on multi-variable environmental data from large-scale datasets such as SAPFLUXNET, COCO or KAGGLE this research is based on in-house experimental data collected in close collaboration with a sensor developer and farmers. The experimental setup reflects practical conditions relevant to controlled environment agriculture. To the best of the authors’ knowledge, this is the first study to investigate the potential of RRN deep learning models to infer sap flow directly from stem diameter signals in tomato plants. A comprehensive performance comparison of the models is presented under varying input time windows, with a discussion on implications for real-time irrigation and plant monitoring solutions. Deep learning models were designed using four advanced Recurrent Neural Networks (RNN) architectures: LSTM, BiLSTM, LRCN, and GRU, trained with past sap flow and stem diameter data from tomato plants. Based on the last three hours of data, the models predicted sap flow for the next hour. Metrics like Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), and R² were used to evaluate performance, and early stopping was applied to prevent overfitting during training. The LSTM model achieved the lowest RMSE, excelling at short-term sap flow prediction. However, both BiLSTM and GRU models performed well overall, particularly in capturing, more significant fluctuations and peaks. R<sup>2</sup> 0.83 values across all models were around 7.2, with MAE values below 5.8, demonstrating robust predictive potential. These results suggest that advanced deep learning models, particularly BiLSTM, can significantly improve the prediction of plant sap flow, enhancing efficiency in water management in precision agriculture.
