Comprehensive Model Performance
This study evaluated four deep neural network architectures—AlexNet, Vision Transformer (ViT), MobileNet, and U-Net—for classifying cucumber plant leaves as healthy or diseased. The results underscore the superior capabilities of modern, more complex architectures for precision agricultural tasks.
Vision Transformer (ViT) emerged as the top performer, achieving an impressive 99.39% accuracy and a 99.52% F1-score. This highlights its exceptional ability to learn complex spatial relationships and robustly classify diseases.
MobileNet also demonstrated excellent performance with 99.00% accuracy and a 99.00% F1-score, proving its efficacy as a lightweight yet highly accurate solution suitable for deployment on resource-constrained devices.
In contrast, U-Net, primarily designed for semantic segmentation, showed moderate performance in classification with 78.23% accuracy and 68.59% F1-score, reflecting its limitations when adapted for whole-image classification without explicit segmentation tasks.
AlexNet yielded the lowest performance, with only 63.00% accuracy and a 39.00% F1-score, indicating its architectural limitations for current complex image classification challenges compared to more advanced models.
Vision Transformer (ViT): Unlocking Global Spatial Intelligence
The Vision Transformer (ViT) architecture, adapted from traditional transformer blocks, processes images by dividing them into fixed patches, converting these into tokens. It then applies a Multi-Head Self-Attention (MHSA) mechanism, allowing it to capture global spatial relationships and subtle patterns across the entire image efficiently.
In this research, ViT achieved the highest accuracy of 99.39% and an F1-score of 99.52%. Its strength lies in its ability to handle complex data and maintain exceptional robustness even under varied field conditions, making it ideal for tasks requiring comprehensive context analysis in plant leaf images.
However, the learning curves suggest a potential for overfitting, with a noticeable gap between training and validation loss (Fig. 7a). This indicates that while powerful, ViT models may require careful regularization strategies and larger, more diverse datasets to maximize generalization in novel environments.
MobileNet: Efficient AI for Edge Deployment
MobileNet is distinguished by its lightweight design, leveraging Depthwise Separable Convolution blocks that split standard convolutions into two stages: depthwise (per-channel) and pointwise (1×1) convolutions. This design significantly reduces computational cost while maintaining high accuracy.
The adapted MobileNet model achieved an impressive 99.00% accuracy and a 99.00% F1-score. Its efficient architecture, combined with ReLU6 activation functions and BatchNorm normalization, makes it well-suited for deployment on resource-constrained devices such as agricultural drones or smartphones.
The training process for MobileNet showed strong generalization capabilities, with training and validation accuracy curves closely aligned (Fig. 7b). This suggests that the model effectively learns key features without significant overfitting, making it a highly practical choice for real-time disease detection in diverse agricultural environments.
Robust Data Handling: Harmonization and Augmentation
The study integrated two publicly available datasets from Kaggle: "Cucumber Leaf Disease Dataset" and "Cucumber Diseases". To ensure consistency, a harmonization process merged all diseased categories into a single "sick" class, and healthy categories into a "healthy" class, forming a unified binary classification scheme (Fig. 1).
Advanced preprocessing techniques were applied to standardize images according to each architecture's input requirements, including resizing and normalization. Furthermore, tailored data augmentation strategies were implemented:
- AlexNet received moderate geometric transformations (rotations, shifts, flipping).
- MobileNet employed a broader augmentation regime (rotations, shifts, shear, zoom, flipping).
- ViT and U-Net focused solely on resizing and standard normalization to preserve their unique architectural requirements.
For U-Net's segmentation task, an automatic mask-generation pipeline was developed using HSV statistics to approximate lesion regions, demonstrating a commitment to comprehensive data preparation for diverse model objectives.

Case Study: Real-time Disease Detection in Smart Agriculture
Scenario: A large-scale cucumber farm faced significant yield losses due to undetected foliar diseases. Manual inspection was time-consuming, prone to human error, and often too late for effective intervention, leading to widespread infections and inefficient use of fungicides.
AI Implementation: The farm integrated a MobileNet-based deep learning system, deployed on low-cost edge devices (e.g., smart cameras mounted on drones) for continuous, real-time monitoring of cucumber plants. This system was trained on diverse leaf images and fine-tuned for the specific disease types prevalent on the farm.
Impact: The MobileNet solution enabled early and accurate identification of disease outbreaks, even subtle initial symptoms. This led to a 30% reduction in fungicide use by allowing targeted, localized treatments instead of broad-spectrum applications. Furthermore, the ability to intervene proactively resulted in a 15% increase in overall cucumber yield and improved crop quality. The low computational footprint of MobileNet made it a cost-effective and scalable solution for field-level deployment, empowering farmers with data-driven decision-making and promoting sustainable agriculture.
