Introduction to the Importance of Detecting Apple Leaf Diseases
Apple trees are one of the main economic crops in China, where issues related to leaf diseases present a significant challenge affecting their growth and productivity. Early and accurate detection of diseases is vital for farmers, as it enables them to take appropriate measures in a timely manner to protect their crops. Traditional detection methods rely heavily on observation and experience, where experts identify diseases based on the color and patterns of the leaves, which is a time-consuming approach that requires highly specialized skills. However, in recent years, the focus has shifted towards using artificial intelligence technology. Object detection techniques have become one of the most common trends in this context. These techniques are used to identify and classify diseases by analyzing images, facilitating the disease detection process and making it more efficient and effective.
Current Methods and Challenges in Detecting Apple Leaf Diseases
There are multiple methods for detecting apple leaf diseases, including traditional image processing techniques and artificial intelligence. Image processing techniques have suffered from limitations in effectiveness, as the ability to distinguish between different diseases, especially when symptoms are similar, is a real challenge. In recent years, disease detection methods have significantly evolved thanks to the use of convolutional neural networks (CNNs). These networks are capable of learning from large datasets and providing accurate results, yet there is a continuous need for improvements in detection accuracy, especially considering the necessity for rapid information assessment in agriculture.
Introducing a New Method for Detecting Apple Leaf Diseases
The proposed method is characterized by its reliance on the YOLOv8 framework, which is known for its efficiency in real-time object detection. This method represents a significant advancement in detection techniques, as it includes three new modules designed to enhance detection accuracy and reduce the impact of environmental factors. The network is developed to be capable of distinguishing the characteristics of various diseases, and it proves to be highly effective in minimizing both false positive and false negative rates. For example, experimental results show that the proposed model achieved an average accuracy rate of 85.1%, surpassing the latest YOLOv10s model. The performance enhancement also results from utilizing an advanced algorithm for controlling classification accuracy and determination, making the model more responsive to the diverse challenges it may face.

The integration of traditional and modern methods can bring about significant transformation in how agricultural diseases are managed. By leveraging big data and advanced algorithms, farmers can greatly improve their agricultural production. The future requires a greater focus on developing lightweight but highly accurate models, which will be key to achieving the strategic vision for enhancing productivity in apple farming.
Data and Challenges in Detecting Apple Leaf Diseases
The health of apple tree leaves is one of the key indicators of the overall health of the tree. Apple leaves are exposed to many diseases that affect productivity and fruit quality. In an effort to accurately detect these diseases, a dataset called AppleLeaf9 was collected, which includes images of apple leaves affected by various diseases. The importance of using deep learning techniques for classifying and testing the data has been highlighted. This dataset consists of a mixture of different datasets such as Plant Village, ATLDSD, PPCD 2020, and PPCD 2021, where the leaves were classified into nine disease categories, including healthy leaves.
However, studies faced challenges related to class balance. While the PlantDoc dataset contains apple leaf diseases in complex environments, the number of classes in it is limited. In contrast, although AppleLeaf9 has a larger number of classes, there is a significant imbalance in the frequency of the classes, making the model prone to detecting the more frequent classes while leaving the less frequent classes vulnerable to errors or lack of detection.
To overcome these issues, the dataset was restructured by removing low-quality images and integrating images with complex backgrounds from the PlantDoc dataset to achieve a more balanced distribution among the classes. Other key challenges include the presence of multiple leaves in the image, varying lighting conditions, and the similarity between disease features, which complicates accurate detection.
YOLOv8s Algorithm and Techniques Used in Disease Detection
The YOLOv8s algorithm is based on the fundamental structure of YOLOv5, with notable improvements including the use of modern modules such as CSP and SPPF, significantly enhancing performance. Sometimes, the algorithm struggles to recognize diseases in images with complex backgrounds or under varying conditions such as lighting, necessitating adjustments and refinements to the algorithm to handle these cases.
The algorithm discusses how to utilize multiple loss functions during training, such as classification loss and box location loss. It relies on an integrated dynamic approach to enhance performance by adjusting the values used in the detection process. For instance, Varifocal Loss is used to control the balance between different groups and gives greater focus to the most significant varieties.
Moreover, the design of a separate head, where the classification head is distinct from the detection head, is one of the methods that improve the model’s flexibility in adapting to the diverse sizes and shapes of targets. This design provides flexible and adaptable performance in real-world environments with complex backgrounds.
Proposed Improvements in Disease Detection Algorithm
Utilizing enhancements in the YOLOv8s algorithm is crucial for improving disease detection accuracy. These enhancements involve important areas such as extracting features of small targets, integrating features across layers, and aligning tasks between detection heads. The focus of improvements on effectively analyzing diseases is achieved by enhancing multi-scale feature representation, facilitating the differentiation between targets in complex images.
Information is managed sequentially through a specific integrated design for converging features, which contributes to enhancing the model’s ability to recognize small targets and improves its capacity to handle congestion points. These processes help correct any potential drift in results and enhance the model’s accuracy in real-world contexts.
Implementation
An advanced algorithm consisting of an integrated network with precise requirements provides a standardized means to understand the effects of the environment and lighting conditions on disease detection. By constructing a carefully designed network structure, high results can be assured in compliance with various targets, even in the most challenging environments.
Enhancing Feature Representation in Disease Recognition Model
In the field of machine learning and computer vision, improving the quality and relevance of input features is a critical factor in developing robust and effective models, especially when dealing with complex images such as images of diseased tree leaves. Input features represent a digital representation of the unique characteristics of the input data, and the more expressive these features are, the greater the model’s ability to recognize patterns and subtle details in the image. In this framework, the proposed model discusses an output feature map that retains the same accuracy as a medium-sized map, while the number of channels is doubled. This technique ensures the effective integration of information from features of different scales, enhancing the model’s ability to differentiate between various traits and improve overall recognition accuracy.
Images contain multiple elements such as leaves and complex backgrounds, requiring the model to be able to accurately identify disease regions. To achieve this, a recurrent attention mechanism has been exploited that enhances the model’s ability to focus its attention on high-importance areas. Instead of relying solely on global information, the studied mechanism deals with dimensional differences, allowing the enhanced benefits to improve the quality of processed features. For example, when information from multiple channels is integrated using algorithms such as pooling techniques and local examination, multi-scale levels can review data from multiple angles, resulting in better classification outcomes.
Introducing the Cascading Attention Unit
When working on models like those adopted in the disease detection project, there arises the need to examine features combined from several levels. Here comes the role of the cascading attention unit, which aims to enhance the model’s ability to focus locally on the targeted disease region. This unit is based on the principle of integrating features from adjacent layers, significantly enhancing the accuracy of identifying specific disease locations. Therefore, the fundamental concept of the attention unit is to present the Hierarchical Attention Layer (H-CAM) as a tool to aid in data processing. This layer helps extract feature attention indicators from different fields, where local and global contexts are calculated in parallel.
The strategy consists of merging local and global context information together to produce calculated attention weights. By reshaping the processing method and using operations like global average pooling with local verification, it is capable of obtaining meaningful contexts. These operations improve the accuracy of feature integration and reduce the potential loss of information from features with small dimensions, ultimately leading to enhanced pattern recognition operations. This systematic approach can effectively avoid challenges associated with scattering and target size variations, thus enhancing the model’s efficiency and effectiveness.
Task-Aligned Dynamic Head Mechanism
One of the key aspects of enhancing model effectiveness is the aggregation of different tasks, such as classification and spatial detection of objects. In examples such as disease detection in apple leaves, the model needs to adapt to ensure that tasks are balanced and stable. The proposed model designs a Dynamic Task-Aligned Head (DTAH) mechanism that emphasizes the necessity for classification and localization tasks to interact, as potential conflicts between the information acquired from each task can lead to less accurate results.
Contributed
The dynamic head mechanism processes potential risks associated with gaps in feature learning across different tasks, which can lead to variations in prediction accuracy. The goal of this design is to enhance the interaction between classification and localization tasks in a way that allows the model to understand the mutual state of the tasks. By using adjustable convolutions, there will be greater room for efficiency tuning, making the model more capable of handling complex information.
.
This is based on the concept of optimizing the individual learning mechanism for each task, while addressing the resulting channels at a consistent level. Class-level attention operations are specifically used to compute the specific features related to each task separately, supporting more accurate inferences. Ultimately, integrating falling attention mechanisms and the dynamic head mechanism is fundamental to the overall model design, increasing recognition accuracy and enhancing the model’s ability to adapt to various challenges.
Classification and Intersection over Union (IoU)
Classification scores and Intersection over Union (IoU) refer to the core aspects of the model’s prediction quality when detecting apple leaf diseases. The essential steps of this process involve measuring how well the predictive boxes align with the true boxes for each disease condition. The alignment value at the anchor-level for each case is calculated by combining the classification scores and IoU values. This is mathematically expressed by the mentioned equation, where p and q represent the classification scores and IoU, respectively. The elements φ and ω determine the impact of each of these aspects in measuring alignment. From a joint optimization perspective, t encourages the network to focus dynamically on the tasks’ compatible anchors, playing a pivotal role in achieving alignment between the two tasks. Thus, the results demonstrate the importance of this formula in enhancing prediction quality and increasing disease detection model accuracy, enabling researchers to evaluate theoretical computations accurately and effectively.
Experimental Setup
PyTorch was used in conjunction with a graphical processing unit (GPU) to build a model for detecting apple leaf diseases. The experiments suggested the idea of using stochastic gradient descent (SGD) while defining the experimental parameters precisely, such as system setup and software environment. The number of training epochs was set to 150, batch size to 16, and input image size to 640×640 pixels. The effectiveness of this setup relies on the experience gained from previous studies and the expected performance of the available equipment. By providing context around the basic experimental setup, this allows for the comparison of results with potential future experiments that may involve improvements or modifications to the current model.
Data Used in Experiments
The proposed algorithm was validated using the ALDD dataset, which contains eight common diseases of apple leaves. This dataset includes 3,638 images representing indicative symptoms of diseases, and those images were annotated using the LabelImg tool under the supervision of specialized experts. This reflects the importance of acquiring accurately recorded data in scientific research to reliably measure the model’s success. In some cases, methods for dealing with ambiguous phenomena when the annotations overlap were clarified, guiding us to make decisions on how to accurately perform classification to avoid misestimations. The dataset and its documentation in various forms also demonstrate how to handle data distortions to organize the information necessary for training the model, reflecting the significance of spatial examination diversity and the unique characteristics of each disease type in conducting effective evaluations.
Evaluation Metrics
Metrics such as Average Precision (AP), Recall (R), and Mean Average Precision (mAP) are vital tools for determining the best model. Recall represents the ratio of correctly identified positive cases to all positive cases the model could identify. Meanwhile, AP is computed based on the area under the precision-recall curve. These metrics are used as comprehensive benchmarks for object detection algorithm performance. Additionally, parameter statistics (Params) refer to the number of trainable parameters within the neural network model, while Frames Per Second (FPS) measures the model’s processing speed. These values assist in understanding the actual model performance, helping to identify whether models employing new image processing and machine learning techniques outperform their execution based on the specified figures in previous experiments.
Results

The results of the experiments conducted on the YOLO-ACT model show the impact of each enhancement module separately on the performance of detecting apple leaf diseases. By integrating modules such as AFF, CAM, and DTAH and analyzing their effects, it was observed that the model’s performance significantly improved. As a result, the overall mean average precision (mAP) increased from 82.3% to 85.1% after adding the DTAH module. This reflects the influence of each enhancement module on improving the model’s ability for precise and dynamic classification. To determine effectiveness, heat maps and focus area detection were utilized, demonstrating that the model enhances its focus on key features while ignoring unimportant areas. Here it becomes clear how these units contribute to improving the overall responsiveness of the model when dealing with complex data, representing a significant advancement in the search for effective solutions for plant disease detection and providing accurate data for farmers.
Comparative Experimental Results
To evaluate the performance of the YOLO-ACT algorithm, reliable comparisons were made with several classical algorithms. The same dataset and training settings were used to ensure a fair comparison. The results showed that the proposed model outperformed in performance metrics such as mAP, while maintaining a good resistance rate to the various complexities of the plant disease world in all cases. For example, comparisons also showed that our model was able to achieve the highest accuracy across various classes and data transitions, making the model not only effective in recognizing typical symptoms but also capable of handling changes within different classes. Thus, the proposed model offers a more accurate and flexible alternative, contributing to the agricultural field by providing precise information that contributes to the overall health of crops and agricultural ventures.
