Official Pytorch code for "MicroAST: Towards Super-Fast Ultra-Resolution Arbitrary Style Transfer"

News:

We have released the codes for calculating SSIM/Style Loss/Content Loss metrics! See details at path metrics/.

Introduction:

MicroAST is a lightweight model that completely abandons the use of cumbersome pre-trained Deep Convolutional Neural Networks (e.g., VGG) at inference. Instead, two micro encoders (content and style encoders) and one micro decoder are utilized for style transfer. The content encoder aims at extracting the main structure of the content image. The style encoder, coupled with a modulator, encodes the style image into learnable dual-modulation signals that modulate both intermediate features and convolutional filters of the decoder, thus injecting more sophisticated and flexible style signals to guide the stylizations. In addition, to boost the ability of the style encoder to extract more distinct and representative style signals, it also introduces a new style signal contrastive loss. MicroAST is 5-73 times smaller and 6-18 times faster than the state of the art, for the first time enabling super-fast (about 0.5 seconds) arbitrary style transfer at 4K ultra-resolutions.

Environment:

• Python 3.6
• Pytorch 1.8.0

Getting Started:

Clone this repo:

git clone https://github.com/EndyWon/MicroAST
cd MicroAST

Test:

• Test a pair of images:

  python test_microAST.py --content inputs/content/1.jpg --style inputs/style/1.jpg

• Test two collections of images:

  python test_microAST.py --content_dir inputs/content/ --style_dir inputs/style/

Train:

• Download content dataset MS-COCO and style dataset WikiArt and then extract them.

• Download the pre-trained vgg_normalised.pth, place it at path models/.

• Run train script:

  python train_microAST.py --content_dir ./coco2014/train2014 --style_dir ./wikiart/train
