Code and data for paper "Deep Painterly Harmonization"

This software is published for academic and non-commercial use only.

This code is based on torch. It has been tested on Ubuntu 16.04 LTS.

Dependencies:

• Torch (with loadcaffe)
• Matlab or Octave

CUDA backend:

• CUDA
• cudnn

Download VGG-19:

sh models/download_models.sh

Compile cuda_utils.cu (Adjust PREFIX and NVCC_PREFIX in makefile for your machine):

make clean && make

To generate all results (in data/) using the provided scripts, simply run

python gen_all.py

in Python and then

run('filt_cnn_artifact.m')

in Matlab or Octave. The final output will be in results/.

Note that in the paper we trained a CNN on a dataset of 80,000 paintings collected from wikiart.org, which estimates the stylization level of a given painting and adjust weights accordingly. We will release the pre-trained model in the next update. Users will need to set those weights manually if running on their new paintings for now.

Removed a few images due to copyright issue. Full set here for testing use only.

Here are some results from our algorithm (from left to right are original painting, naive composite and our output):

• Our torch implementation is based on Justin Johnson's code;
• Histogram loss is inspired by Risser et al.
