<h1 align="center">NeuroMap — Brain Tumor Detection & Classification</h1>

<p align="center">
  Deep Learning based Brain Tumor Classification System with Grad-CAM Explainability
</p>

<hr>

<h2>Overview</h2>

<p>
NeuroMap is a Flask-based web application that uses a Convolutional Neural Network (CNN) to classify brain MRI scans into four categories:
</p>

<ul>
  <li>Glioma</li>
  <li>Meningioma</li>
  <li>Pituitary Tumor</li>
  <li>No Tumor</li>
</ul>

<p>
The system also integrates Grad-CAM visualization to highlight regions in the MRI image that influenced the model’s decision.
</p>
