This is the official Tensorflow implementation of our paper:

Attention-aware Multi-stroke Style Transfer, CVPR 2019. [Project] [arXiv]

Overview

This project provides an arbitrary style transfer method that achieves both faithful style transfer and visual consistency between the content and stylized images. The key idea of the proposed method is to employ self-attention mechanism, multi-scale style swap and a flexible stroke pattern fusion strategy to smoothly and adaptably apply suitable stroke patterns on different regions. In this manner, the synthesized images of our method can be more visually pleasing and generated in one feed-forward pass.

Examples

Prerequisites

• Python (version 2.7)
• Tensorflow (>=1.4)
• Numpy
• Matplotlib

Download

• MSCOCO dataset is applied for the training of the proposed self-attention autoencoder.
• Pre-trained VGG-19 model.

Usage

Test

Make sure there exists a sub-folder named test_result under images folder, then run

$ python test.py --model tf_model/aams.pb \
                        --content images/content/lenna_cropped.jpg \
                        --style images/style/candy.jpg \
                        --inter_weight 1.0

both of the stylized image and the attention map will be generated in test_result.

Our model is trained with tensorflow 1.4.

Train

Download the MSCOCO dataset and filter out images with unsuitable format(grayscale,etc) by running

$ python filter_training_images.py --dataset datasets/COCO_Datasets/val2014

then

$ python train.py --dataset datasets/COCO_Datasets/val2014
