One of the most serious threats to global food security is plant diseases compromising agricultural productivity and threatening the livelihoods of millions. These diseases can decimate crops, disrupt food supply chains, and escalate the risk of food shortages, underscoring the urgency of implementing robust strategies to safeguard the world’s food sources. Deep learning methods have revolutionized the field of plant disease detection, offering advanced and accurate solutions for early identification and management. However, a recurring problem in deep learning models is their susceptibility to a lack of robustness and generalization when facing novel crop and disease types that were not included in the training dataset. In this paper, we address this issue by proposing a novel deep learning-based system capable of recognizing diseased and healthy leaves across different crops, even if the system was not trained on them. The key idea is to focus on recognizing the diseased small leaf regions rather than the overall appearance of the diseased leaf, along with determining the disease’s prevalence rate on the entire leaf. For efficient classification and to leverage the excellence of the Inception model in disease recognition, we employ a small Inception model architecture, which is suitable for processing small regions without compromising performance. To confirm the effectiveness of our method, we trained and tested it using the widely acclaimed PlantVillage dataset, recognized as the most utilized dataset for its comprehensive and diverse coverage. Our method achieved an accuracy rate of 94.04%. Furthermore, when tested on new datasets, it achieved an accuracy rate of 97.13%. This innovative approach not only enhances the accuracy of plant disease detection but also addresses the critical challenge of model generalization to diverse crops and diseases. In addition, it outperformed the existing methods in its ability to identify any disease across any crop type, showcasing its potential for broad applicability and contribution to global food security initiatives.
全球粮食安全面临的最严重威胁之一是危害农业生产力并威胁数百万人生计的植物病害。这些疾病可摧毁作物,扰乱粮食供应链,并加剧粮食短缺的风险,因此迫切需要实施强有力的战略,保护世界粮食来源。深度学习方法彻底改变了植物病害检测领域,为早期识别和管理提供了先进而准确的解决方案。然而,深度学习模型中一个反复出现的问题是,当面对未包含在训练数据集中的新作物和疾病类型时,它们容易缺乏鲁棒性和泛化。在本文中,我们通过提出一种新的基于深度学习的系统来解决这个问题,该系统能够识别不同作物的病叶和健康叶,即使系统没有对它们进行训练。关键思想是重点识别患病的小叶片区域,而不是患病叶片的整体外观,同时确定疾病在整个叶片上的患病率。为了有效的分类和利用Inception模型在疾病识别中的优点,我们采用了一个小的Inception模型架构,它适合处理小区域而不影响性能。为了确认我们方法的有效性,我们使用广受好评的PlantVillage数据集进行训练和测试,该数据集因其全面和多样化的覆盖范围而被公认为是最常用的数据集。该方法的准确率为94.04%。在新的数据集上进行测试,准确率达到97.13%。这种创新的方法不仅提高了植物病害检测的准确性,而且解决了模型泛化到不同作物和病害的关键挑战。此外,它在识别任何作物类型的任何疾病方面的能力优于现有方法,显示了其广泛适用性和对全球粮食安全倡议作出贡献的潜力。

Accurately estimating the severity of cucumber diseases is crucial for improving cucumber quality and minimizing economic losses. Deep learning techniques have shown promising results in automatically extracting disease image features for severity estimation. However, existing methods still face challenges in accurately estimating disease severity under complex backgrounds and achieving real-time performance.This paper presents a lightweight severity estimation method called DM-BiSeNet to address these challenges. The proposed method utilizes BiSeNet V2 as the base network and incorporates depthwise separable convolutional blocks to optimize the detail branch. A simplified MobileNet V3 network is also constructed to optimize the semantic branch. The model training process is accelerated using the AdamW optimizer. To evaluate the performance of DM-BiSeNet, a dataset consisting of cucumber powdery mildew and downy mildew disease images collected in natural scenes is utilized. Experimental results demonstrate that DM-BiSeNet achieves higher accuracy in severity estimation, with an R2 value of 0.9407 and an RMSE of 1.0680, outperforming the comparison methods. Moreover, DM-BiSeNet exhibits a complexity of 1.54 GFLOPs and is capable of reasoning 94 disease images per second.The proposed DM-BiSeNet model offers a lightweight and effective solution for accurate and rapid severity estimation of cucumber diseases under complex backgrounds. It provides a valuable technical tool for quantitative disease estimation, offering significant potential for practical applications.
准确估计黄瓜病害的严重程度对提高黄瓜品质和减少经济损失至关重要。深度学习技术在自动提取疾病图像特征用于严重程度估计方面显示出有希望的结果。然而,现有的方法在复杂背景下准确估计疾病严重程度和实现实时性方面仍然面临挑战。本文提出了一种称为DM-BiSeNet的轻量级严重性估计方法来解决这些挑战。该方法以BiSeNet V2为基础网络,结合深度可分卷积块对细节分支进行优化。构建了简化的MobileNet V3网络,对语义分支进行了优化。使用AdamW优化器加速模型训练过程。为了评估DM-BiSeNet的性能,利用自然场景中收集的黄瓜白粉病和霜霉病图像数据集。实验结果表明,DM-BiSeNet在严重性估计上取得了更高的精度,R2值为0.9407,RMSE为1.0680,优于对比方法。此外,DM-BiSeNet显示出1.54 GFLOPs的复杂性,每秒能够推理94张疾病图像。提出的DM-BiSeNet模型为复杂背景下黄瓜病害严重程度的准确快速估计提供了一种轻量级、有效的解决方案。它为疾病定量估计提供了一种有价值的技术工具,为实际应用提供了巨大的潜力。

In crop image recognition, when faced with a large quantity of unlabeled data, the traditional manual labeling method requires a large amount of human and material resources. To solve this problem, this study proposes an image recognition method based on a pseudolabeling technique. First, the data are divided into labeled and unlabeled data. The initial network model is trained on labeled data. Then, pseudolabeling of the unlabeled data is predicted, and only the data that satisfy the confidence threshold are regarded as valid pseudolabeling. To convert the unlabeled data into supervised training data, the two types of data are mixed. The training is terminated when the number of remaining unlabeled data satisfies the end condition and when the fivefold cross-validation method is used to evaluate model performance. Compared with the traditional semisupervised method, the experimental method is simpler and more applicable. Experiments were conducted on rice growth stage recognition and crop weed seedling recognition tasks. The results showed that the proposed method achieved 99.17% accuracy in rice growth stage recognition and a high AUC value of 99.93% in crop weed seedling recognition, which demonstrated excellent performance. Compared with the traditional model, this method not only improves in accuracy but also has better stability and wider applicability and is expected to provide an efficient, accurate and scalable solution for crop image recognition.
在农作物图像识别中,当面对大量未标注数据时,传统的人工标注方法需要耗费大量的人力物力。为了解决这一问题,本研究提出了一种基于伪标记技术的图像识别方法。首先,将数据分为有标记数据和未标记数据。初始网络模型是在标记数据上进行训练的。然后,对未标记数据进行伪标记预测,只有满足置信度阈值的数据才被视为有效的伪标记。为了将未标记数据转换为监督训练数据,将两种类型的数据混合在一起。当剩余未标记数据数量满足结束条件,并使用五重交叉验证方法评估模型性能时,训练结束。与传统的半监督方法相比,实验方法更简单,适用范围更广。对水稻生育期识别和作物杂草苗期识别任务进行了实验研究。结果表明,该方法在水稻生育期识别中准确率达到99.17%,在作物杂草苗期识别中AUC值高达99.93%,具有较好的识别效果。与传统模型相比,该方法不仅提高了精度,而且具有更好的稳定性和更广泛的适用性,有望为农作物图像识别提供高效、准确和可扩展的解决方案。

With the increasing emphasis on sustainable energy and the advancements in modern agriculture, flexible agricultural power loads present challenges to the reliable operation of the agricultural energy internet. However, research on the coupling of energy system security with agricultural security is insufficient and fails to consider the impacts of meteorological elements on agricultural power loads. To address these gaps, this paper establishes load models for irrigation and light supplementation based on the actual cultivation demands of winter dragon fruit in Guangxi province. A static security index system is developed to analyze the security, considering the unique features of agricultural power demands. The condition of the distribution network is assessed by comparing the indexes with predefined limits, using a China 41-bus distribution network. Finally, the optimal scheme for nocturnal supplemental lighting treatment and irrigation is determined based on the method for maintaining secure operation of the distribution network. This study serves as a guide for simulating current farming power loads and demonstrates how security analysis of the agricultural energy internet contributes to the large-scale and sophisticated development of modern agriculture.
随着人们对可持续能源的日益重视和现代农业的发展,灵活的农业电力负荷对农业能源网络的可靠运行提出了挑战。然而,对能源系统安全与农业安全耦合的研究较少,且未考虑气象要素对农业电力负荷的影响。针对这些不足,本文根据广西冬季火龙果的实际栽培需求,建立了灌溉补光负荷模型。针对农用电力需求的特点,建立了静态安全指标体系来分析农用电力的安全性。以中国某41母线配电网为例,通过将指标与预定义限值进行比较,对配电网状况进行了评价。最后,在保证配电网安全运行的基础上,确定了夜间补光处理和灌溉的最佳方案。本研究为当前农业电力负荷的模拟提供了指导,并论证了农业能源互联网的安全分析如何促进现代农业的规模化、精细化发展。

The inconsistency in the quality of dried products at different coordinates within a conventional multi-stage convective cabinet dryer is a critical but often neglected problem. In this study, the drying behavior (moisture ratio) occurring in each drying tray layer and the drying characteristics (shrinkage or area ratio) occurring at different coordinates within a multi-stage convective cabinet dryer was assessed. Potato slices were used as raw materials in the drying process. Experiments were carried out by varying three different hot air velocities and two different drying temperatures. It was found that under the same hot air temperature and air velocity, the change in moisture content in each drying tray and the shrinkage in each coordinate of the potato slices were different. Artificial neural network model was used to predict the moisture ratio and the area ratio of the potato slices based on the experimental data. The moisture ratio obtained from the experiment was evaluated by comparing it with the drying model. The results showed a good confidence level with the coefficient of determination in the range of 0.962 7–0.993 3. The shrinkage analysis was based on the photographic data taken through image processing before usage as the output data for the predictive model. The predictive model was designed to have various architectures with different parameters; both hidden layer and hidden layer size, learning rate, training cycles, sampling type and split ratio. The best moisture ratio and area ratio model provided the coefficient of determination of 0.996 and 0.970, respectively.
在传统的多级对流柜式干燥机中,干燥产品在不同坐标上的质量不一致是一个严重但经常被忽视的问题。在这项研究中,干燥行为(水分比)发生在每个干燥盘层和干燥特性(收缩率或面积比)发生在不同的坐标在多级对流柜式干燥机进行了评估。以马铃薯片为原料进行干燥。实验通过改变三种不同的热风速度和两种不同的干燥温度进行。研究发现,在相同的热风温度和风速下,每个干燥盘的含水率变化和马铃薯片各坐标的收缩率是不同的。基于实验数据,采用人工神经网络模型对马铃薯片的含水率和面积比进行预测。通过与干燥模型的比较,对实验所得的含水率进行了评价。结果表明,测定系数在0.962 ~ 0.993范围内,具有较好的置信水平。收缩分析是基于使用前通过图像处理获得的照片数据作为预测模型的输出数据。预测模型被设计成具有不同参数的不同架构;隐藏层和隐藏层的大小,学习率,训练周期,采样类型和分割比率。最佳水分比模型和面积比模型的决定系数分别为0.996和0.970。

Our prior study focused on development of internet of things (IoT) and edge-compute enabled crop physiology sensing system (CPSS) for apple sunburn monitoring. Edge compute algorithm on CPSS estimated sunburn susceptibility as fruit surface temperature (FST) through pixel-by-pixel multiplication of captured thermal infrared images with segmented fruits binary mask. The segmentation was performed using color-based K means clustering approach. This limited CPSS applicability to monitor sunburn of red colored cultivars only and when fruits develop color, typically late growing season. This is a key research gap as recent weather patterns have shown that sunburn can occur during early growing season when fruits are green to yellow. Therefore, aim of this study was to develop and field evaluate cultivar and color independent mask region-convolution neural network (R-CNN) aided fruit segmentation model and edge compute compatible FST estimation algorithm. Season long field data were collected in 2021 using eight CPSS nodes (three in cv. WA38 [Cosmic crisp] and five in cv. Honeycrisp). Collected data were used to develop and validate mask R-CNN based fruit segmentation model. Developed mask R-CNN based model was able to segment fruits of two apple cultivars and of varying colors with 91.4 % average precision. In orchard evaluations (2022 season), the resulting algorithm ported on CPSS was able to accurately segment (dice similarity coefficient = 0.89) and estimate apple FST with < 0.5 °C error compared to ground truth data. With compute time of about 37 s, data processing time was reduced by 22 % over previous algorithm. High ambient temperature (>35 °C) on a warmer day resulted in multiple throttling errors caused by excessive CPU temperature; however, the CPSS performance was uncompromised in FST estimation. Ambient air temperature did not affect RAM utilization and CPU clock frequency. Overall, developed FST algorithm can potentially be used as input to actuate water-based cooling system.
我们之前的研究重点是开发物联网(IoT)和边缘计算支持的作物生理传感系统(CPSS),用于苹果晒伤监测。基于CPSS的边缘计算算法通过对采集到的带有水果二值掩模的热红外图像逐像素相乘来估计晒伤敏感性为水果表面温度。使用基于颜色的K均值聚类方法进行分割。这限制了CPSS仅用于监测红色品种的晒伤以及果实变色时(通常是生长季节后期)的适用性。这是一个关键的研究空白,因为最近的天气模式表明,晒伤可能发生在水果从绿色到黄色的早期生长季节。因此,本研究的目的是开发和现场评估品种和颜色无关的掩膜区域卷积神经网络(R-CNN)辅助水果分割模型和边缘计算兼容的FST估计算法。2021年,使用8个CPSS节点(3个在cv中)收集了整个季节的现场数据。WA38[宇宙脆]和5英寸cv。密脆)。利用收集到的数据开发并验证了基于掩模R-CNN的水果分割模型。开发的基于R-CNN的掩模模型能够以91.4%的平均精度分割两个苹果品种和不同颜色的果实。在果园评价(2022年)中,移植到CPSS上的结果算法能够准确分割(dice similarity coefficient = 0.89),并使用<;与地面真实数据相比误差0.5°C。计算时间约为37 s,数据处理时间比以前的算法减少了22%。天气较暖时环境温度过高(>35°C),导致CPU温度过高导致多个节流错误;然而,在FST估计中,CPSS的性能没有受到影响。环境空气温度不影响RAM利用率和CPU时钟频率。总的来说,开发的FST算法可以作为驱动水基冷却系统的输入。

Early crop yield prediction provides critical information for Precision Agriculture (PA) procedures, policymaking, and food security. The availability of Remote Sensing (RS) datasets and Machine Learning (ML) approaches improved the prediction of sugarcane crop yield on the local and global scales, but an additional effort on the plot scale prediction is required. Challenges for plot-level prediction include a high ratooning capacity of the sugarcane crop, the lack of high spatial resolution data during the critical growth stages, and the non-linear complexation of yield data. The principal objective of the study is to analyse the potential of a time series of high-resolution multispectral Unmanned Aerial Vehicle (UAV) imagery along with three advanced ML techniques, namely Random Forest Regression (RFR), Support Vector Regression (SVR), and Nonlinear Autoregressive Exogenous Artificial Neural Network (NARX ANN) as a solution to the plot-level sugarcane yield prediction. An experimental sugarcane field containing 48 plots was selected, and UAV imagery was collected during the three consecutive cropping seasons' early and middle crop growth stages. Each dataset per growth stage was analyzed separately to predict the sugarcane crop yield in an attempt to discover how early the prediction of pre-harvest yield can be achieved. The datasets of the first two cropping seasons were trained and tested using the three ML techniques, utilizing 10-fold cross-validation to avoid overfitting. The third cropping season dataset was then used to evaluate the reliability of the developed prediction models. The results show that the correlation of Vegetation Indices (VIs) with crop yield in the middle stage outperforms the early stage in all three ML models. Moreover, comparing these models indicates that the NARX ANN method outperformed the others in the middle stage with the highest correlation coefficient (R2) of 0.96 and the lowest Root Mean Square Error (RMSE) of 4.92 t/ha. It was followed by the SVR (R2 = 0.52, RMSE of 14.85 t/ha), which performed similarly to the RFR method (R2 = 0.48, RMSE = 11.20 t/ha). In conclusion, the best-suited model for predicting sugarcane yields during the middle growth stage is a NARX ANN model employing the Normalized Difference RedEdge (NDRE), which demonstrates the feasibility of the ML approaches to predict the plot level sugarcane yield at a specific period of growth as they are less sensitive to the inconsistency of data collection times.
作物早期产量预测为精准农业(PA)程序、政策制定和粮食安全提供关键信息。遥感(RS)数据集和机器学习(ML)方法的可用性改善了甘蔗作物在局部和全球尺度上的产量预测,但需要在地块尺度上进行额外的预测。甘蔗田级预测面临的挑战包括甘蔗作物的高再生能力、关键生育期缺乏高空间分辨率数据以及产量数据的非线性复杂性。该研究的主要目的是分析高分辨率多光谱无人机(UAV)时间序列图像的潜力,以及三种先进的机器学习技术,即随机森林回归(RFR),支持向量回归(SVR)和非线性自回归外源性人工神经网络(NARX ANN)作为地块水平甘蔗产量预测的解决方案。选取48块甘蔗试验田,在连续3个种植季作物生长早中期采集无人机影像。对每个生长阶段的每个数据集进行单独分析,以预测甘蔗作物产量,试图发现收获前产量的预测可以多早实现。前两个种植季节的数据集使用三种ML技术进行训练和测试,使用10倍交叉验证以避免过拟合。然后利用第三个种植季数据来评估所建立的预测模型的可靠性。结果表明,三种ML模型的中期植被指数(VIs)与作物产量的相关性均优于早期。结果表明,NARX神经网络方法在中期表现优于其他方法,相关系数(R2)最高,为0.96,均方根误差(RMSE)最低,为4.92 t/ha。其次是SVR (R2 = 0.52, RMSE = 14.85 t/ha),其结果与RFR方法相似(R2 = 0.48, RMSE = 11.20 t/ha)。综上所述,最适合预测甘蔗生长中期产量的模型是采用归一化差分差分(NDRE)的NARX神经网络模型,这表明ML方法对数据采集时间不一致的敏感性较低,可以预测特定生长时期地块水平的甘蔗产量。

Modelling the energy use and microclimate of a greenhouse can be a valuable tool for commercial growers, making it possible to predict the impact of making changes to greenhouse systems and operation. This allows energy saving scenarios to be identified and can reduce energy use costs. In this study, a lumped capacitance thermal model is developed to simulate the greenhouse interior microclimate based on exterior conditions and operating settings. The current study incorporated many aspects of a complex commercial greenhouse not commonly seen in literature, such as evaporative cooling pads, dehumidification technology, gas burners, energy curtains, supplementary heating and lighting, and forced ventilation. The model was successfully validated at multiple greenhouse sections of a commercial greenhouse during spring, summer, and fall conditions in the southern Ontario climate. Data was collected from the greenhouse from March to November of 2019 at 15-minute intervals. The measured interior temperature and relative humidity data were used to evaluate the accuracy of the model simulations, while other measurements, such as solar radiation, were used as model inputs. The study greenhouse was unique, as potted rose crops were cycled between sections during the growth stage. This made variation in plant properties relatively small during the different seasons. Detailed information on the model methodology was included to improve reader’s understanding. Overall, the model accuracy is comparable or even better when compared to similar models in the literature, proving it is versatile and can be used as a design tool moving forward. In the future, the current model will be used to conduct comparative analyses of a range of different energy-use reduction technologies and operating procedures (including year-round production) to quantify the most economically and practically feasible options specifically for Ontario greenhouse growers.
对温室的能源使用和小气候进行建模对商业种植者来说可能是一个有价值的工具,使其能够预测改变温室系统和操作的影响。这样就可以确定节能方案,并降低能源使用成本。本文基于室外条件和操作条件,建立了集总电容热模型来模拟温室室内小气候。目前的研究纳入了文献中不常见的复杂商业温室的许多方面,如蒸发冷却垫、除湿技术、燃气燃烧器、能源窗帘、补充供暖和照明以及强制通风。该模型在安大略省南部春季、夏季和秋季气候条件下的商业温室的多个温室部分成功验证。从2019年3月到11月,每隔15分钟从温室收集数据。测量的室内温度和相对湿度数据被用来评估模式模拟的准确性,而其他测量数据,如太阳辐射,被用作模式输入。研究温室是独特的,因为盆栽玫瑰作物在生长阶段在不同的区段之间循环。这使得植物特性在不同季节的变化相对较小。详细介绍了模型的方法,以提高读者的理解。总体而言,与文献中的类似模型相比,该模型的准确性相当甚至更好,证明了它的通用性,可以用作向前发展的设计工具。未来,目前的模型将用于对一系列不同的节能技术和操作程序(包括全年生产)进行比较分析,以量化安大略省温室种植者最经济和最实际可行的选择。

The increase in the worldwide population reflects the expansion of beef cattle production and exportation. Although pasture is the world’s primary feed source of cattle food, failures in pasture management can endanger the productivity of beef cattle. An option for reducing the issues brought on by a shortage of nutritional resources and maintaining the fodder pasture is to perform the supplementation process on the livestock, even being one of the most costly activities in animal management. To decrease expenses and the need for labor to supplement the herd and improve animal performance, many parameters directly associated with supplementation must be monitored, such as environmental climate, soil and pasture characteristics, animal welfare, weight, and health. With so many parameters that impacts the decision on the quality and quantity of supplement to be supplied to the herd, sensors, remote sensing, and agricultural machinery are essential. The joint usage of these technologies in the supplementation process is complex, and there is a gap in decision-making systems for dynamic supplementation. Therefore, this work aims to carry out a comprehensive literature review that characterizes the main technologies related to the bovine supplementation process, mapping the main processes that involve the use of technological tools in the most diverse application domains. Finally, we propose a new Internet of Things architecture focused on the cattle supplementation process that combines technologies to compose a dynamic supplementation decision-making system capable of estimating the quantity and quality of the supplement that the herd needs in the presence of changes in the environment, pasture, and animals’ conditions parameters to reach production targets.
世界人口的增加反映了肉牛生产和出口的扩大。虽然牧场是世界上牛的主要饲料来源,但牧场管理的失败可能危及肉牛的生产力。减少营养资源短缺和维持饲料牧场所带来的问题的一个选择是对牲畜进行补充过程,即使是动物管理中最昂贵的活动之一。为了减少费用和对劳动力的需求,以补充畜群和提高动物的生产性能,必须监测许多与补充直接相关的参数,如环境气候、土壤和牧场特征、动物福利、体重和健康。由于有如此多的参数影响着决定向畜群提供补品的质量和数量,传感器、遥感和农业机械是必不可少的。这些技术在补充过程中的联合使用是复杂的,并且在动态补充的决策系统方面存在空白。因此,这项工作旨在进行全面的文献综述,描述与牛补充过程相关的主要技术,绘制涉及在最多样化的应用领域使用技术工具的主要过程。最后,我们提出了一种新的物联网架构,以牛的补充过程为重点,结合技术组成一个动态补充决策系统,能够在环境、牧场和动物条件参数发生变化的情况下,估计牛群所需的补充数量和质量,以达到生产目标。

Tree-ring dating enables gathering necessary knowledge about trees, and it is essential in many areas, including forest management and the timber industry. Tree-ring dating can be conducted on either wood’s clean cross-sections or tree trunks’ rough end cross-sections. However, the measurement process is still time-consuming and frequently requires experts who use special devices, such as stereoscopes. Modern approaches based on image processing using deep learning have been successfully applied in many areas, and they can succeed in recognizing tree rings. While supervised deep learning-based methods often produce excellent results, they also depend on extensive datasets of tediously annotated data. To our knowledge, there are only a few publicly available ring image datasets with annotations. We introduce a new carefully captured dataset of images of hardwood species automatically annotated for tree ring detection. We capture each wood cookie twice, once in the rough form, similar to industrial settings, and then after careful cleaning, that reveals all growth rings. We carefully overlap the images and use them for an automatic ring annotation in the rough data. We then use the Feature Pyramid Network with Resnet encoder that obtains an overall pixel-level area under the curve score of 85.72% and ring level F1 score of 0.7348. The data and code are available at https://github.com/wufanyou/growth-ring-detection.
树木年轮测年可以收集有关树木的必要知识,它在许多领域都是必不可少的,包括森林管理和木材工业。树木年轮测年既可以在木材的干净横截面上进行,也可以在树干的粗端横截面上进行。然而,测量过程仍然很耗时,并且经常需要使用特殊设备的专家,例如立体镜。基于深度学习的图像处理的现代方法已经成功地应用于许多领域,它们可以成功地识别树木年轮。虽然基于监督的深度学习方法通常会产生出色的结果,但它们也依赖于大量带有冗长注释的数据集。据我们所知,只有少数公开可用的带有注释的环状图像数据集。我们引入了一个新的精心捕获的硬木物种图像数据集,该数据集自动注释用于树木年轮检测。我们将每个木质饼干捕获两次,一次是粗糙的形式,类似于工业环境,然后经过仔细的清洁,显示所有的生长环。我们仔细地重叠图像,并将它们用于粗糙数据中的自动环形注释。然后,我们使用带有Resnet编码器的特征金字塔网络,得到曲线下的总体像素级面积为85.72%,环级F1得分为0.7348。数据和代码可在https://github.com/wufanyou/growth-ring-detection上获得。
