Crop Disease Image Dataset (5 Crops, 19 Classes)

Dataset Summary

The Crop Disease Image Dataset is a curated, high-quality agricultural image dataset designed for computer vision, deep learning, and smart farming applications. It contains 22,169 RGB leaf images spanning 5 major crops across 19 distinct healthy and diseased classes.

This dataset was constructed by collecting, filtering, and standardizing images from multiple open-source agricultural repositories (such as the PlantVillage Dataset and Mendeley's 15 Crop and 45 Disease Dataset) to create a unified resource for training models like MobileNetV3, ResNet, EfficientNet, and Vision Transformers (ViT).

This dataset forms the core AI vision module for the IoT-Based Crop Disease Detection System for Smart Agriculture project.

Recommended Usage & Preprocessing

Data Splitting Strategy

For robust evaluation and avoiding data leakage across classes, a stratified split is strongly recommended:

• Train: 70%
• Validation: 15%
• Test: 15%

Data Augmentation & Pipelines

When loading data into frameworks like PyTorch (torchvision) or TensorFlow (tf.keras), standard spatial transformations improve model generalization:

• Resize & Center Crop (e.g., 224x224 or 256x256)
• Pixel Normalization (ImageNet mean & std)
• Random Flips, Rotations, and Color Jittering

Project Context: Dual-Module IoT System

This vision dataset forms Module 1 of a broader smart agriculture framework:

1. Vision Module (This Dataset): Image-based leaf diagnosis using Deep Learning models deployed on local/edge devices.
2. Sensor Module: Environmental monitoring using IoT sensors (Temperature, Humidity, Soil Moisture) fed into tabular ML models to assess environmental risk.

Limitations

• Lighting & Occlusion: Images originate from controlled and semi-controlled settings; real field conditions (direct glare, severe shadows, partial leaves) might require targeted fine-tuning.
• Class Imbalance: Minor imbalance exists between classes (e.g., Potato healthy vs. Tomato Bacterial spot). Class-weighted loss functions are recommended.
