# 🥔 Potato Leaf Disease Classification using CNN

This project is a **Deep Learning–based Potato Leaf Disease Classifier** built using a **Convolutional Neural Network (CNN)**.  
The model classifies potato leaf images into **Healthy**, **Early Disease Detection**, and **Late Disease Detection** stages, helping in **early identification and prevention of crop loss**.

---

## 🚀 Project Objective

- Detect potato leaf diseases at an early stage  
- Reduce crop damage by enabling timely treatment  
- Provide an automated and accurate classification system using Deep Learning

---

## 🧠 Model Overview

- Model Type: **Convolutional Neural Network (CNN)**
- Learning Type: **Supervised Learning**
- Framework: **TensorFlow + Keras**
- Visualization: **Matplotlib**

---

## 🏷️ Classes

The dataset is categorized into **three classes**:

1. **Healthy Leaf**
2. **Early Disease Detection**
3. **Late Disease Detection**

---

## 📂 Dataset Description

- Image-based dataset of potato leaves  
- Contains real-world leaf images
