AgriSentry Maize Disease Classifier

A CNN-based disease classification model for maize crops, part of the AgriSentry diagnostic system.

Model Details

Model Description

This is a TensorFlow CNN model trained to classify diseases in maize plants. It identifies three common maize diseases and healthy crop status.

• Model type: Convolutional Neural Network (CNN)
• Framework: TensorFlow/Keras
• Task: Image Classification
• Input: RGB images (224x224 pixels)
• Output: Disease classification with confidence scores

Supported Classes

• Healthy: No disease detected
• Common Rust: Common rust fungal infection
• Northern Corn Leaf Blight: NCLB fungal disease
• Gray Leaf Spot: Gray spot fungal disease

Model Features

• Input resolution: 224x224 RGB images
• Optimized for corn/maize field conditions
• Fast inference suitable for mobile/edge deployment
• Confidence scores for each prediction

Usage

Via Hugging Face Inference API

from huggingface_hub import InferenceClient

client = InferenceClient(model="your-username/agrisentry-maize-disease-classifier")

# Load image and send for inference
with open("maize_leaf.jpg", "rb") as f:
    result = client.image_classification(f)

print(result)

Via Python (TensorFlow)

import tensorflow as tf
from PIL import Image
import numpy as np

model = tf.keras.models.load_model('maize_cnn.h5')
img = Image.open('maize_leaf.jpg').resize((224, 224))
img_array = np.array(img) / 255.0
prediction = model.predict(np.expand_dims(img_array, axis=0))

Training Data

• Collected from maize-growing regions
• Augmented with rotation, zoom, and brightness variations
• Balanced across disease classes

Performance

• Accuracy: ~96% on validation set
• Optimized for real-world field images

Limitations

• Best performance with well-lit, close-up leaf images
• May require model fine-tuning for new disease variants
• Designed specifically for maize crops
