Neural Style Transfer

The repository contains PyTorch implementation of the Gatys et al. paper with some modifications. In the paper, the authors proposed algorithm that transfers style from one input image (the style image) into second image (the content image).

Examples

Some of the hand picked results:

Setup

1. Clone the repository git clone https://github.com/gcerar/pytorch-neural-style-transfer
2. Enter directory cd pytorch-neural-style-transfer
3. Run conda env create -f ./environment.yml
4. Run conda activate style-transfer

It is recommended to use GPU to accelerate the style transfer process.

Usage

python style_transfer.py --input <TargetImgPath> --style <StyleImgPath>

Optional parameters:

• --help or -h print help with all available parameters
• --epochs <number> (default: 7000)
• --seed <number> (default: 1)
• --no-cuda disables CUDA acceleration and use CPU instead
• --optimizer <adam|adamw|lbfgs|sgd> (default: adam)
• --init <input|noise> decide on what is init of output image (default: input)
