Introduction

This project is based on the Neural-Style algorithm developed by Leon A. Gatys, Alexander S. Ecker and Matthias Bethge. Neural-Style, or Neural-Transfer, allows you to take an image and reproduce it with a new artistic style. The algorithm takes three images, an input image, a content-image, and a style-image, and changes the input to resemble the content of the content-image and the artistic style of the style-image.

We have referred to the paper Gatys_Image_Style_Transfer_CVPR_2016_paper.pdf for understanding the underlying principles.

Here are a few examples of the style transfer in action:

Examples

Features

• Apply the style of famous artworks to your photos.
• Adjustable style strength.
• Supports multiple image formats.
• Easy to use command-line interface.

Installation

Prerequisites

• Python 3.6 or higher
• Git
• Virtual environment (optional but recommended)

Steps

1. Clone the repository:

   git clone https://github.com/swas-kar/Neural_Style_Transfer.git
   cd Neural_Style_Transfer

2. Create and activate a virtual environment:

   python3 -m venv venv
   source venv/bin/activate   # On Windows use `venv\Scripts\activate`

3. Install the required dependencies:

   pip install -r requirements.txt

Arguments

• --content: Path to the content image.
• --style: Path to the style image.
• --output: Path to save the output image.
• --iterations: Number of iterations to run (default: 500).
• --style-weight: Weight of the style (default: 1e6).
• --content-weight: Weight of the content (default: 1).
