+# Vehicle Classifier AI
+
+## Description
+
+- Developed a high-performance **Vehicle Image Recognizer** web app using **deep learning techniques**.
+- Designed and implemented a **Convolutional Neural Network (CNN)** with **TensorFlow** and **Keras** to classify various vehicle types.
+- Integrated a **Flask** server for backend functionality, allowing users to upload vehicle images and receive real-time predictions.
+- Supports recognition of vehicles including **bus, family sedan, fire engine, heavy truck, jeep, minibus, racing car, SUV, taxi, and truck**.
+
+## Features
+
+- **Real-Time Predictions:** Utilized Flask to manage image uploads and provide on-the-fly predictions for the type of vehicle.
+- **Interactive Web App:** Designed an intuitive web interface where users can easily upload images and get immediate classification results.
+- **Highly Accurate Model:** Trained the CNN on a dataset of 1,400 images for training and 200 images for validation, leading to a highly performant model.
+
+## Tech Stack
+
+- **Programming Language:** Python
+- **Machine Learning Libraries:** TensorFlow, Keras
+- **Web Framework:** Flask
+- **Frontend Technologies:** HTML5, CSS3, JavaScript
+- **Dataset:** 
+  - Vehicle classification dataset from Kaggle: [Kaggle Dataset](https://www.kaggle.com/datasets/marquis03/vehicle-classification)
+
+## Installation Instructions
+
+`Run all the cells in jupyter, you will have vehicle_model.h5. Now follow the instructions`
+
+1. Clone the GitHub repository:
+   ```bash
+   git clone https://github.com/UppuluriKalyani/ML-Nexus.git
+   ```
+
+2. Navigate to the project directory:
+   ```bash
+   cd Neural Networks
+   cd Vehicle Classifier
+   ```
+
+3. Install the required Python packages:
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+4. Run the Flask app:
+   ```bash
+   python app.py
+   ```
+
+5. Open your web browser and go to `http://127.0.0.1:5000` to use the app.
