Introduction

The repository contains the testing codes and pretrained weights for Anime2Sketch.

Anime2Sketch is a sketch extractor that works well on illustration, anime art, and manga. It is an application based on the paper "Adversarial Open Domain Adaption for Sketch-to-Photo Synthesis".

Prerequisites

• Linux or macOS
• Python 3 (Recommend to use Anaconda)
• CPU or NVIDIA GPU + CUDA CuDNN
• Pillow, PyTorch

Get Started

Installation

Install the required packages: pip install -r requirements.txt

Download Pretrained Weights

Please download the weights from GoogleDrive, and put it into the weights/ folder.

Test

python3 test.py --dataroot /your_input/dir --load_size 512 --output_dir /your_output/dir

The above command includes three arguments:

• dataroot: your test file or directory
• load_size: due to the memory limit, we need to resize the input image before processing. By default, we resize it to 512x512.
• output_dir: path of the output directory

Run our example:

python3 test.py --dataroot test_samples/madoka.jpg --load_size 512 --output_dir results/

Train

This project is a sub-branch of AODA. Please check it for the training instructions.
