Unsupervised Volumetric Animation
This repository contains the source code for the CVPR'2023 paper Unsupervised Volumetric Animation. For more qualitiative examples visit our project page.
Here is an example of several images produced by our method. On the left is sample visualization: In the first column the driving video is shown. For the remaining columns the top image is animated by using motions extracted from the driving. On the right is rotation visualization: We show source image as well as rotated rgb, depth, normals and segments.

Installation
We support python3
. To install the dependencies run:
pip install -r requirements.txt
YAML configs
There are several configuration files one for each dataset
in the config
folder named as config/dataset_name_stage.yaml
. We adjust the configuration to run on 8 A100 GPU.
Pre-trained checkpoints
Checkpoints can be found under this link.
Inversion
Inversion, to run inversion on your own image use:
python inversion.py --config config/dataset_name.yaml --driving_video path/to/driving --source_image path/to/source --checkpoint tb-logs/vox_second_stage/{time}/checkpoints/last.cpkt
The result can be seen with tensorboard.
Training
To train a model, fist, download the mraa checkpoints and place them into ./
.
Then run the following commands:
python train.py --config config/vox_first_stage.yaml
# [Optional] To save time one could first train with 128 resolution:
python train.py --config config/vox_second_stage_128.yaml --checkpoint tb-logs/vox_first_stage/{time}/checkpoints/last.cpkt
python train.py --config config/vox_second_stage.yaml --checkpoint tb-logs/vox_first_stage/{time}/checkpoints/last.cpkt
