Sketch Your Own GAN: A Creative Exploration

In the world of Generative Adversarial Networks (GANs), the ability to customize generated images based on user input is a transformative capability. The project titled “Sketch Your Own GAN” takes this innovation a step further by allowing users to create images tailored to their sketches. Imagine wielding a digital brush that can orchestrate the powers of a pre-trained GAN—creating visual masterpieces that resonate with your artistic intent!

How It Works

This remarkable technique allows you to input a hand-drawn sketch, and the GAN adapts its capabilities to harmonize with your creative input. Think of it like teaching a pet to imitate your dance moves; it learns your style precisely while keeping the underlying rhythm intact! The GAN shifts the object’s shape and poses according to your sketch, while maintaining details like color, texture, and background effortlessly.

Getting Started with Sketch Your Own GAN

• Clone the Repository:

  Begin by cloning the project repository with the command:

  bash
  git clone git@github.com:PeterWang512/GANSketching.git
  cd GANSketching
  

• Install Required Packages:

  PyTorch is essential for this project. Install it alongside other requirements by executing:

  bash
  pip install -r requirements.txt
  

• Download Model Weights:

  Run the following command to download the necessary model weights:

  bash
  bash weights/download_weights.sh
  

• Generate Samples:

  Here’s how you can generate samples using different models:

  python generate.py --ckpt weights/photosketch_standing_cat_noaug.pth --save_dir output/samples_standing_cat
  python generate.py --ckpt weights/by_author_cat_aug.pth --save_dir output/samples_teaser_cat
  python generate.py --ckpt weights/by_author_face0_aug.pth --save_dir output/samples_ffhq_face0 --size 1024 --batch_size 20
  

Latent Space Edits

The GANSpace integration in this project retains the ability to edit the latent space of the original model. This means you can add fur to a standing cat or cleverly close its eyes using the given commands:

python ganspace.py --obj cat --comp_id 27 --scalar 50 --layers 2,4 --ckpt weights/photosketch_standing_cat_noaug.pth --save_dir output/ganspace_fur_standing_cat
python ganspace.py --obj cat --comp_id 45 --scalar 60 --layers 5,7 --ckpt weights/photosketch_standing_cat_noaug.pth --save_dir output/ganspace_eye_standing_cat

Troubleshooting

Running into bumps while using Sketch Your Own GAN? Here are some common issues and how you can solve them:

• Issue: Errors when downloading weights or datasets.
  Solution: Check your internet connection and ensure that you’re executing the commands within the project directory.
• Issue: Difficulty generating samples.
  Solution: Verify that you’ve correctly installed all required packages and that the model weights are updated. If you downloaded weights earlier, rerun bash weights/download_weights.sh to update them.
• Issue: Output images don’t match expectations.
  Solution: Ensure that your sketches are detailed and clear; the GAN performs best with identifiable shapes and outlines.
