DM-VTON: Distilled Mobile Real-time Virtual Try-On

[Paper] [Colab Notebook] [Web Demo]

This is the official pytorch implementation of DM-VTON: Distilled Mobile Real-time Virtual Try-On. DM-VTON is designed to be fast, lightweight, while maintaining the quality of the try-on image. It can achieve 40 frames per second on a single Nvidia Tesla T4 GPU and only take up 37 MB of memory.

📝 Documentation

Installation

This source code has been developed and tested with python==3.10, as well as pytorch=1.13.1 and torchvision==0.14.1. We recommend using the conda package manager for installation.

1. Clone this repo.

git clone https://github.com/KiseKloset/DM-VTON.git

2. Install dependencies with conda (we provide script scripts/install.sh).

conda create -n dm-vton python=3.10
conda activate dm-vton
bash scripts/install.sh

Data Preparation

VITON

Because of copyright issues with the original VITON dataset, we use a resized version provided by CP-VTON. We followed the work of Han et al. to filter out duplicates and ensure no data leakage happens (VITON-Clean). You can download VITON-Clean dataset here.

Inference

test.py run inference on image folders, then evaluate FID, LPIPS, runtime and save results to runs/TEST_DIR. Check the sample script for running: scripts/test.sh. You can download the pretrained checkpoints here.

Note: to run and save separate results for each pair [person, garment], set batch_size=1.

Training

For each dataset, you need to train a Teacher network first to guide the Student network. DM-VTON uses FS-VTON as the Teacher. Each model is trained through 2 stages: first stage only trains warping module and stage 2 trains the entire model (warping module + generator). Check the sample scripts for training both Teacher network (scripts/train_pb_warp + scripts/train_pb_e2e) and Student network (scripts/train_pf_warp + scripts/train_pf_e2e). We also provide a Colab notebook as a quick tutorial.

Training Settings

A full list of trainning settings can be found in opt/train_opt.py. Below are some important settings.

• device: Device (gpu) for performing training (e.g. 0,1,2). DM-VTON needs a GPU to run with cupy.
• batch_size: Customize batch_size for each stage to optimize for your hardware.
• lr: learning rate
• Epochs = niter + niter_decay
  • niter: Number of epochs using starting learning rate.
  • niter_decay: Number of epochs to linearly decay learning rate to zero.
• save_period: Frequency of saving checkpoints after save_period epochs.
• resume: Use if you want to continue training from a previous process.
• project and name: The results (checkpoints, logs, images, etc.) will be saved in the project/name folder. Note that if the folder already exists, the code will create a new folder (e.g. project/name-1, project/name-2).`
