Plant Leaf Disease Detection System

🌱 Introduction

The Plant Leaf Disease Detection System is an Artificial Intelligence and Deep Learning based application developed to identify plant diseases from leaf images. The system analyzes uploaded plant leaf images and predicts whether the leaf is healthy or diseased using image processing and Convolutional Neural Network (CNN) techniques.

The project was developed during the internship program to understand practical applications of Machine Learning, Deep Learning, and Computer Vision in agriculture. The system helps farmers and agricultural users identify diseases at an early stage and take preventive actions to reduce crop loss.
