Welcome to an adventurous journey into the world of GANs and dense visual alignment! In this article, we will take you through the steps to deploy the GANgealing algorithm, explaining each step in a user-friendly manner. Let’s dive in!

What is GANgealing?

GANgealing, derived from the concept of GAN-Supervised Learning, is an exciting technique that aids in learning discriminative models and their GAN-generated training data. It’s adept at solving the dense visual alignment problem through a clever method involving a Spatial Transformer that “warps” random samples from a GAN to align them to a common target.

Setting Up Your Environment

A smooth start requires a proper setup. Here’s how to do it:

• Clone the repository to your local machine:

git clone https://github.com/wpeebles/gangealing.git
cd gangealing

• Next, add it to your PYTHONPATH:

export PYTHONPATH=$PYTHONPATH:$PWD

• You can set up your environment using Conda:

conda env create -f environment.yml
conda activate gg

Running Pre-trained Models

To run a pre-trained model, simply use the following command:

python applications/propagate_to_images.py --ckpt cat --real_data_path data/lsun_cats --real_size 512

Here you can specify different models such as bicycle, dog, and TV monitor by adjusting the --ckpt parameter accordingly.

Preparing Real Data

GANgealing uses LMDB for storing data. To prepare real datasets, these commands can be handy:

• Automatically download and pre-process LSUN Cats images:

python prepare_data.py --input_is_lmdb --lsun_category cat --out data/lsun_cats --size 512 --max_images 10000

• For a folder with images, you can pre-process them with:

python prepare_data.py --path folder_of_images --out data/my_new_dataset --pad center --size S

Running on Images

To process images, use:

python applications/propagate_to_images.py --ckpt cat --real_data_path data/lsun_cats --real_size 512

You can enhance this by adding custom modifications, such as introducing specific objects or labels.

Understanding the Code: An Analogy

Let’s liken the GANgealing process to an artist preparing to paint a magnificent landscape. The artist (GAN) has a blank canvas (random samples) and requires consistent colors to create a beautiful scene. The Spatial Transformer acts as a special brush that seamlessly blends colors across the canvas while the artist adjusts the color palette (updating the target mode) to make painting easier. Ultimately, the artist can create a breathtaking scene by translating ideas over a unique blank canvas, producing something majestic.

Troubleshooting Your Setup

As with any sophisticated tool, challenges may arise. Here are some troubleshooting tips:

• Ensure your PyTorch version is at least 1.10.1; older versions may face compatibility issues.
• If experiencing performance issues, consider switching between CUDA and cuDNN versions based on your GPU.
