Image Cartoonifier

A Flask-based web application that transforms photographs into cartoon-style images using advanced image processing techniques with OpenCV. Upload any image and watch it transform into an artistic cartoon version! Features

1. Web-based Interface: Clean, intuitive UI with a modern design
2. Fast Processing: Real-time image cartoonification using K-means clustering
3. Multiple Format Support: Accepts PNG, JPG, and JPEG images
4. Edge Detection: Intelligent edge detection using adaptive thresholding
5. Color Quantization: Reduces the color palette for an artistic cartoon effect
6. Responsive Design: Works seamlessly on desktop and mobile devices
7. Dark Theme UI: Modern glassmorphism design with animated background

How It Works The cartoonification process involves:

Grayscale Conversion: Converting the image to grayscale for edge detection Median Blur: Applying blur to reduce noise Edge Detection: Using adaptive thresholding to detect image edges K-means Clustering: Reducing colors to create a simplified, artistic palette Edge Overlay: Combining edges with the color-reduced image for the final cartoon effect

Installation Prerequisites

• Python 3.7 or higher
• pip (Python package manager)

Setup

Clone the repository:

bash git clone https://github.com/anshjain0316/Image-Cartoonifier.git cd Image-Cartoonifier

Create a virtual environment (recommended):

bash python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate

Install dependencies:

bash pip install -r requirements.txt

Usage

1. Start the Flask application:

bashpython app.py

2. Open your browser and navigate to:

http://localhost:5000

3. Select an image from your device
4. Click the "Cartoonify!" button
5. Download or view the cartoonized result
