Welcome, aspiring artists and tech enthusiasts! If you’re looking to transform your anime art or manga into beautiful line sketches, look no further than Anime2Sketch. This powerful sketch extractor leverages cutting-edge technology to take illustrations to the next level. In this blog post, we’ll guide you step-by-step on how to set up and use Anime2Sketch, while sharing some troubleshooting tips along the way.

What is Anime2Sketch?

Anime2Sketch is an innovative project designed for extracting sketches from illustration, anime art, and manga. Developed using advanced machine learning techniques, this tool allows you to create stunning line arts with minimal effort. Think of it as your personal art assistant, capable of converting your detailed images into clean sketches, much like turning a rough draft into a polished masterpiece.

Prerequisites: Setting Up Your Environment

Before diving into the installation, ensure your system meets the following prerequisites:

• Operating System: Linux or macOS
• Python 3 (recommended to use Anaconda)
• CPU or NVIDIA GPU + CUDA CuDNN
• Required Packages: Pillow, PyTorch

Step 1: Installation

Begin by installing the necessary packages to get Anime2Sketch up and running. Execute the following command in your terminal:

pip install -r requirements.txt

Step 2: Download Pretrained Weights

Next, you’ll need to download the pretrained weights:

• Regular Model: Google Drive
• Artifact-Free Model (for low contrast images): Google Drive

Be sure to place these weights in the ‘weights’ folder within your project directory.

Step 3: Testing the Model

Run the test script by using the command below. This command includes three important arguments:

• dataroot: Specify your test file or directory.
• load_size: The input image will be resized To manage memory constraints (default size is 512×512).
• output_dir: The directory where your output sketches will be saved.

python3 test.py --dataroot your_inputdir --load_size 512 --output_dir your_outputdir

For an example scenario, you can use:

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

Step 4: Running with Docker

If you prefer a Docker setup, you can customize your input and output images directory effortlessly:

• To build the Docker image, run:

make docker-build

• Customize your input/output directory using Docker’s volume mount. Then run:

docker run -it --rm --gpus all -v pwd:workspace -v your_input_dir:input -v your_output_dir:output anime2sketch

• If you need to run with CPU only, modify the Dockerfile and command accordingly.

Troubleshooting

If you encounter any issues while using Anime2Sketch, here are some troubleshooting steps to consider:

• Ensure all prerequisites are correctly installed.
• Double-check the paths for your input and output directories.
• If you see a memory error, consider reducing the load_size parameter.
• For any technical inquiries, feel free to leave questions as issues in the repository.
