In this guide, we will delve into the exciting realm of OOTDiffusion, a groundbreaking project designed for controllable virtual try-on experiences using advanced latent diffusion techniques. From setting up your environment to executing your first run, we will make this as user-friendly as possible. Let’s dive in!

What is OOTDiffusion?

OOTDiffusion stands for “Outfitting Fusion based Latent Diffusion for Controllable Virtual Try-on.” It’s an innovative tool that allows users to virtually “try on” clothing and accessories using AI-driven algorithms. By leveraging latent diffusion methods, users can experience a seamless and realistic virtual fitting room right from their devices.

Getting Started

Follow these steps to get OOTDiffusion up and running:

• Clone the GitHub Repository: Start by cloning the OOTDiffusion repository from GitHub. You can do this using the following command:

git clone https://github.com/levihsu/OOTDiffusion

• Try Out OOTDiffusion: You can also try out the online demo provided by the creators directly here.
• Set Up Your Environment: It’s necessary to have a Linux environment for this project. We recommend using Ubuntu 22.04.
• Download Required Models: Make sure to download the required model checkpoints:
  • VITON-HD for half-body models.
  • Dress Code for full-body models.
• Install ONNX for Human Parsing: The project supports ONNX, so you’ll need to install the required packages. You can check the ONNX repository for more information.
• Download CLIP Model: To enhance your experience, download clip-vit-large-patch14 into the checkpoints folder.

Understanding the Code through Analogy

Imagine you are a chef in a kitchen preparing a gourmet meal. In this kitchen, the ingredients (models) are crucial for creating a delicious dish (virtual try-on experience). Each major component of the OOTDiffusion code corresponds to a specific task the chef must handle:

• Cloning the Repo: This is like gathering your ingredients from the pantry. By cloning the GitHub repository, you collect all necessary files and scripts.
• Setting Up the Environment: Just as you need the right tools (pots, pans, utensils) to cook, installing Ubuntu 22.04 ensures that all components function properly together.
• Downloading Models: Each model represents specific recipes that guide you on how to prepare various dishes—a half-body recipe or a full-body recipe, depending on your requirements.
• Running the Code: Finally, combining all the ingredients in the right order and cooking them appropriately will lead you to your flavorful output, much like running the implemented code gives you a realistic virtual try-on experience.

Troubleshooting

If you encounter any issues while setting up or running OOTDiffusion, here are several troubleshooting tips:

• Check Environment Compatibility: Ensure you’re using Ubuntu 22.04, as the code hasn’t been tested on other operating systems.
• Model Download Issues: If models aren’t downloading correctly, check your internet connection and retry downloading from the provided links.
• Installation Issues: If ONNX isn’t functioning as expected, ensure all dependencies are correctly installed. Refer to the ONNX repository for guidance.
