Special Issue Information

Dear Colleagues,

Rapid urbanization, population growth, climate change, and depleting natural resources have raised global food security concerns. Recently, agriculture has changed to using smart farming with innovations in artificial intelligence (AI), big data analytics, Internet of Things (IoT), and automation/robotics, which aim to improve productivity and quality. In this context, there has been rapid advancements in sensing technologies, connectivity, and data analytics techniques, leading to more cost-effective and reliable systems for smart agriculture. Some areas of innovation and advancement include multi- and hyper-spectral imaging, thermal imaging, and color and 3D imaging (including RGB-D). In smart farming, the term 'Agriculture 5.0' refers to the merging of AI and IoT, also known as Artificial Intelligence of Things (AIoT). These technologies work in synergy: AI enriches IoT through machine learning and deep-learning-based data analytics capabilities, while IoT enriches AI through data acquisition, connectivity, and exchange. AIoT-based systems are increasingly used for smart agriculture applications such as crop growth monitoring, pest and disease detection, microclimate monitoring and control, crop yield mapping, targeted spraying, smart irrigation, and nutrient management. Powerful computational infrastructure and associated data analytics techniques, including deep learning, also played an instrumental role in improving the robustness and reliability and widening practical applications of sensing technologies in all aspects of production agriculture. Therefore, this Special Issue aims to promote a deeper understanding of major conceptual and technical challenges and to facilitate the spread of recent breakthroughs in sensing, computer vision, data fusion, and integrated sensor networks for smart farming. Topics of interest include but are not limited to the following:

  • Computer vision for agricultural automation and robotics;
  • Monitoring/decision support systems for crop/livestock management;
  • Sensors and computer vision systems for plant phenotyping;
  • IoT, big data, and data analytics for smart agriculture;
  • IoT-based sensing and computer vision for greenhouses, plant factories, and vertical farms;
  • Edge-AI applications for smart farming;
  • Edge-Cloud collaborative learning for smart farming;
  • AIoT-driven UAV applications for smart farming;
  • UAV-based sensing and computer vision for smart farming.

Wheat stripe rust poses a serious threat to the quality and yield of wheat crops. Typically, the occurrence data of wheat stripe rust is characterized by small sample sizes, and the current research on severity identification lacks high-precision methods for small sample data. Additionally, the irregular edges of wheat stripe rust lesions make it challenging to draw samples. In this study, we propose a method for wheat stripe rust severity identification that combines SLIC superpixel segmentation and a random forest algorithm. This method first employs SLIC to segment subregions of wheat stripe rust, automatically constructs and augments a dataset of wheat stripe rust samples based on the segmented patches. Then, a random forest model is used to classify the segmented subregion images, achieving fine-grained extraction of wheat stripe rust lesions. By merging the extracted subregion images and using pixel statistics, the percentage of lesion area is calculated, ultimately enabling the identification of the severity of wheat stripe rust. The results show that our method outperforms unsupervised classification algorithms such as watershed segmentation and K-Means clustering in terms of lesion extraction when using the segmented subregion dataset of wheat stripe rust. Compared to the K-Means segmentation method, the mean squared error is reduced by 1.2815, and compared to the watershed segmentation method, it is reduced by 2.0421. When compared to human visual inspection as the ground truth, the perceptual loss for lesion area extraction is 0.064. This method provides a new approach for the intelligent extraction of wheat stripe rust lesion areas and fading green areas, offering important theoretical reference for the precise prevention and control of wheat stripe rust.

Efficiently managing temperature and humidity in a pig house is crucial for enhancing animal welfare. This research endeavors to develop an intelligent temperature and humidity control system grounded in a three-way decision and clustering algorithm. To establish and validate the effectiveness of this intelligent system, experiments were conducted to compare its performance against a naturally ventilated pig house without any control system. Additionally, comparisons were made with a threshold-based control system to evaluate the duration of temperature anomalies. The experimental findings demonstrate a substantial improvement in temperature regulation within the experimental pig house. Over a 24 h period, the minimum temperature increased by 4 °C, while the maximum temperature decreased by 8 °C, approaching the desired range. Moreover, the average air humidity decreased from 73.4% to 68.2%. In summary, this study presents a precision-driven intelligent control strategy for optimizing temperature and humidity management in pig housing facilities. Full article
