Lesion-Aware Enhanced Swin Transformer for Plant Disease Identification
This paper introduces LAE-Swin, a novel framework for plant disease identification. It combines a Swin Transformer backbone with a Lesion-Aware Local Enhancement (LALE) module to improve fine-grained lesion feature capture while maintaining global context. LAE-Swin achieves state-of-the-art accuracy on PlantVillage (99.91%) and Sugarcane Leaf Disease (92.07%) datasets, outperforming CNNs and standard Vision Transformers in both controlled and real-world conditions.

Performance & Results
The LAE-Swin framework introduces a novel Lesion-Aware Local Enhancement (LALE) module. This module integrates three synergistic components: feature-wise color space transformation, multi-scale atrous convolution, and lesion attention weighting. Additionally, the standard Swin Block is enhanced by replacing the ReLU activation with GELU in the MLP layers to facilitate more nuanced feature learning. This ensures precise capture of subtle disease cues critical for distinguishing similar diseases.

Key Components of LALE Module
The Lesion-Aware Local Enhancement (LALE) module addresses the issue of standard Transformers underrepresenting subtle local lesion cues. It uses a feature-wise HSV-like color space transformation for invariance to non-lesion variations, multi-scale atrous convolution to capture lesion details across scales without spatial resolution loss, and lesion attention weighting to suppress background noise. Residual links ensure global context preservation.
| Feature | Standard Transformer Limitations | LAE-Swin Advantages |
|---|---|---|
| Local Detail Capture | Struggles with fine-grained local lesions due to window-based attention prioritizing global context. |
|
| Multi-Scale Lesions | Fixed receptive fields limit ability to capture lesions of varying sizes. |
|
| Robustness to Noise | Susceptible to background clutter and intra-class variability. |

Extensive experiments on PlantVillage and a real-field Sugarcane Leaf Disease dataset demonstrate the superiority of LAE-Swin. It achieves state-of-the-art accuracies, outperforming strong baselines including ResNet50, ViT-Base, and the original Swin-Base. The model's balanced performance across majority and minority classes confirms its robustness to real-world challenges.
