Special Issue Information

Dear Colleagues,

With the rapid increase in the world population, agriculture first moved on from manual operation to mechanization and is now moving toward the implementation of automated/robotic field operations to meet the growing demand for food. However, in contrast to industrial operations, agricultural field operations are complex, unstructured, ill defined, and subject to a high degree of variation in illumination, atmospheric, and landscape conditions in addition to the dynamic biological nature of both field and specialty crops. These challenges make it extremely difficult to implement automated/robotic solutions in agricultural field operations. However, with the technological advancements in GPS (global positioning systems), smart sensors, UAVs (unmanned aerial vehicles), GIS (geographic information systems), the IoT (Internet of Things), machine vision, artificial intelligence, blockchain, big data, cybernetics, nanotechnology, digital agriculture, precision agriculture, smart decision support systems, advanced control system, etc., the use of automated/robotic operations in agriculture is becoming a reality.

The aim of this issue is to collect outstanding articles focusing on (but not limited to) robot solutions for various field operations (e.g., planting, irrigation, path planning and navigation, fertilization, spraying, canopy management, pollination, thinning, pruning, weed removal, precision crop load management, harvesting, postharvest transportation, and storage) for both field and specialty crops, precision agriculture applications, advanced in-field sensing and decision support systems, machine vision, artificial intelligence, deep learning, machine learning, big data, IoT, cybernetics, nanotechnology, digital agriculture, UAVs (unmanned aerial vehicles), mechatronics, smart sensors, swarm robotics, and nanorobotics applications in agriculture.

Currently, deep convolutional neural networks have achieved great achievements in semantic segmentation tasks, but existing methods all require a large number of annotated images for training and do not have good scalability for new objects. Therefore, few-shot semantic segmentation methods that can identify new objects with only one or a few annotated images are gradually gaining attention. However, the current few-shot segmentation methods cannot segment plant diseases well. Based on this situation, a few-shot plant disease semantic segmentation model with multi-scale and multi-prototypes match (MPM) is proposed. This method generates multiple prototypes and multiple query feature maps, and then the relationships between prototypes and query feature maps are established. Specifically, the support feature and query feature are first extracted from the high-scale layers of the feature extraction network; subsequently, masked average pooling is used for the support feature to generate prototypes for a similarity match with the query feature. At the same time, we also fuse low-scale features and high-scale features to generate another support feature and query feature that mix detailed features, and then a new prototype is generated through masked average pooling to establish a relationship with the query feature of this scale. Subsequently, in order to solve the shortcoming of traditional cosine similarity and lack of spatial distance awareness, a CES (cosine euclidean similarity) module is designed to establish the relationship between prototypes and query feature maps. To verify the superiority of our method, experiments are conducted on our constructed PDID-5i dataset, and the mIoU is 40.5%, which is 1.7% higher than that of the original network. Full article

Blueberries are widely planted because of their rich nutritional value. Due to the problems of dense adhesion and serious occlusion of blueberries during the growth process, the development of automatic blueberry picking has been seriously hindered. Therefore, using deep learning technology to achieve rapid and accurate positioning of blueberries in the case of dense adhesion and serious occlusion is one of the key technologies to achieve the automatic picking of blueberries. To improve the positioning accuracy, this paper designs a blueberry recognition model based on the improved YOLOv5. Firstly, the blueberry dataset is constructed. On this basis, we design a new attention module, NCBAM, to improve the ability of the backbone network to extract blueberry features. Secondly, the small target detection layer is added to improve the multi-scale recognition ability of blueberries. Finally, the C3Ghost module is introduced into the backbone network, which reduces the number of model parameters while ensuring the accuracy, thereby reducing the complexity of the model to a certain extent. In order to verify the effectiveness of the model, this paper conducts experiments on the self-made blueberry dataset, and the mAP is 83.2%, which is 2.4% higher than the original network. It proves that the proposed method is beneficial to improve the blueberry recognition accuracy of the model. Full article
