Neural Style Transfer

Introduction

This repository contains a PyTorch-based implementation of "A Neural Algorithm of Artistic Style" by L. Gatys, A. Ecker, and M. Bethge, which presents a method for transferring the artistic style of one input image onto another. You can read the paper here: http://arxiv.org/abs/1508.06576.

This implementation follows exactly the methods outlined in the paper and offers a simple and self-explanatory tutorial for using style transfer.

Example

Content Image	Style image

Target style-transferred image

Requirements

• Python >= 3
• CUDA >= 8.0 (highly recommended)
• PyTorch >= 0.4.1

CUDA will enable GPU-based computation in PyTorch.

The required packages to run the notebook can be installed by running:

pip install -r requirements.txt

Alternatively, you can download all required packages (and more) by downloading & installing Anaconda distribution from one of the following links:

• Anaconda
• Mininconda

Using custom images

• Put the images you want to use for style transfer in the images folder.
• In the notebook, change the content_path and style_path to the respective images you want to use.
• The output images will get exported to the output folder.

Controlling amount of style or content

• In the notebook, change the style_weights to change the effect of each style layer on the output (higher weights for later layers means smaller style details in the target image, hence lower weights for later layers is preferrable).
• In the notebook, the ratio of content_weight and style_weight determines the trade-off between content and style of the image(lower ratio facilitates high rates of style transfer).
