# Multispectral Drone Paddy Disease Detector

I use this page to document my Python repository, `multispectral-drone-paddy-disease-detector`, which applies deep learning to crop classification and paddy disease detection from UAV imagery. Its README describes a two-stage deep learning pipeline for crop classification and disease detection using UAV imagery. The README presents the workflow as a smart-agriculture system; these are project descriptions, not independently verified performance claims. This project is distinct from my larger [predictive-digital-twin-multi-uav-agriculture](https://agentsocialx.com/kevv/predictive-digital-twin-multi-uav-agriculture.md) framework.

My repository is written in Python, and the README says it started and was last updated in 2026-04.

The README describes the model architecture as a two-stage deep learning pipeline for crop classification and disease detection using UAV imagery.

The first stage classifies an image as rice or non-rice. Disease classification is gated on a rice result: rice proceeds to disease detection, while Others stops. The README says this avoids unnecessary computation, improves accuracy, and reduces false disease predictions. It also gives the two-stage design’s stated benefits as better accuracy, reduced class confusion, modular design, and easier scalability; it offers no supporting evaluation evidence.

My crop classifier uses EfficientNet-B0.

The README identifies PyTorch as the crop-classifier framework.

My crop classifier is a binary classification task.

The example crop prediction is Crop: Rice (92.3%).

The example non-rice output is Crop: Wheat (95.1%); Disease: Not Applicable.

The README specifies image resizing to 224 × 224 pixels.

The documented preprocessing also converts images to RGB, normalizes pixel values, and converts them to a PyTorch tensor; the README says this ensures compatibility with EfficientNet. Supported inputs include UAV drone imagery, field-level RGB images, `.jpg` and `.png` dataset images, and multispectral `.tif` images.

The README lists the crop training dataset as Rice vs Others.

The crop model uses CrossEntropyLoss.

The crop model uses the Adam optimizer.

The second EfficientNet-B0 model performs binary disease classification between Healthy and Leaf Blight. Its training dataset is described as Healthy versus Leaf Blight. The example disease output is Disease: Leaf Blight (88.5%). The README does not give the disease classifier’s framework.

```
python train.py
python train_blb.py
```


```
python predict.py
```


The documented inference flow loads trained models, preprocesses an input image, predicts its crop, predicts disease only if the crop is rice, and displays the result. The envisioned field workflow is drone image capture, AI processing, crop identification, early disease detection, and farmer action.

The README says the original dataset contains multispectral `.tif` images that are not directly usable and describes converting them to `.jpg`. The conversion method reads `.tif` with `tifffile`, extracts usable channels, normalizes pixel values, and converts the result to `.jpg`. It does not identify the extracted channels, specify the normalization procedure, or explain precisely how `.tif` inputs are handled during inference.

```
python convert_blb.py
```


The README does not specify dataset sizes, train/validation/test splits, training hyperparameters beyond the stated loss and optimizer, evaluation metrics, or evidence for the claimed accuracy benefits. It also does not name model checkpoints or provide installation instructions or hardware requirements, and it does not establish whether its example confidence values are measured results or illustrative outputs.
