+

+ + + Overall framework of UniAnimate +

+
+ +Recent diffusion-based human image animation techniques have demonstrated impressive success in synthesizing videos that faithfully follow a given reference identity and a sequence of desired movement poses. Despite this, there are still two limitations: i) an extra reference model is required to align the identity image with the main video branch, which significantly increases the optimization burden and model parameters; ii) the generated video is usually short in time (e.g., 24 frames), hampering practical applications. To address these shortcomings, we present a UniAnimate framework to enable efficient and long-term human video generation. First, to reduce the optimization difficulty and ensure temporal coherence, we map the reference image along with the posture guidance and noise video into a common feature space by incorporating a unified video diffusion model. Second, we propose a unified noise input that supports random noised input as well as first frame conditioned input, which enhances the ability to generate long-term video. Finally, to further efficiently handle long sequences, we explore an alternative temporal modeling architecture based on state space model to replace the original computation-consuming temporal Transformer. Extensive experimental results indicate that UniAnimate achieves superior synthesis results over existing state-of-the-art counterparts in both quantitative and qualitative evaluations. Notably, UniAnimate can even generate highly consistent one-minute videos by iteratively employing the first frame conditioning strategy. + + +## Getting Started with UniAnimate + + +### (1) Installation + +Installation the python dependencies: + +``` +git clone https://github.com/ali-vilab/UniAnimate.git +cd UniAnimate +conda create -n UniAnimate python=3.9 +conda activate UniAnimate +conda install pytorch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2 pytorch-cuda=11.8 -c pytorch -c nvidia +pip install -r requirements.txt +``` +We also provide all the dependencies in `environment.yaml`. + +**Note**: for Windows operating system, you can refer to [this issue](https://github.com/ali-vilab/UniAnimate/issues/11) to install the dependencies. Thanks to [@zephirusgit](https://github.com/zephirusgit) for the contribution. If you encouter the problem of `The shape of the 2D attn_mask is torch.Size([77, 77]), but should be (1, 1).`, please refer to [this issue](https://github.com/ali-vilab/UniAnimate/issues/61) to solve it, thanks to [@Isi-dev](https://github.com/Isi-dev) for the contribution. + +### (2) Download the pretrained checkpoints + +Download models: +``` +!pip install modelscope +from modelscope.hub.snapshot_download import snapshot_download +model_dir = snapshot_download('iic/unianimate', cache_dir='checkpoints/') +``` +Then you might need the following command to move the checkpoints to the "checkpoints/" directory: +``` +mv ./checkpoints/iic/unianimate/* ./checkpoints/ +``` + +Finally, the model weights will be organized in `./checkpoints/` as follows: +``` +./checkpoints/ +|---- dw-ll_ucoco_384.onnx +|---- open_clip_pytorch_model.bin +|---- unianimate_16f_32f_non_ema_223000.pth +|---- v2-1_512-ema-pruned.ckpt +└---- yolox_l.onnx +``` + +### (3) Pose alignment **(Important)** + +Rescale the target pose sequence to match the pose of the reference image: +``` +# reference image 1 +python run_align_pose.py --ref_name data/images/WOMEN-Blouses_Shirts-id_00004955-01_4_full.jpg --source_video_paths data/videos/source_video.mp4 --saved_pose_dir data/saved_pose/WOMEN-Blouses_Shirts-id_00004955-01_4_full + +# reference image 2 +python run_align_pose.py --ref_name data/images/musk.jpg --source_video_paths data/videos/source_video.mp4 --saved_pose_dir data/saved_pose/musk + +# reference image 3 +python run_align_pose.py --ref_name data/images/WOMEN-Blouses_Shirts-id_00005125-03_4_full.jpg --source_video_paths data/videos/source_video.mp4 --saved_pose_dir data/saved_pose/WOMEN-Blouses_Shirts-id_00005125-03_4_full + +# reference image 4 +python run_align_pose.py --ref_name data/images/IMG_20240514_104337.jpg --source_video_paths data/videos/source_video.mp4 --saved_pose_dir data/saved_pose/IMG_20240514_104337 +``` +We have already provided the processed target pose for demo videos in ```data/saved_pose```, if you run our demo video example, this step can be skipped. In addition, you need to install onnxruntime-gpu (`pip install onnxruntime-gpu==1.13.1`) to run pose alignment on GPU. + +**✔ Some tips**: + +- > In pose alignment, the first frame in the target pose sequence is used to calculate the scale coefficient of the alignment. Therefore, if the first frame in the target pose sequence contains the entire face and pose (hand and foot), it can help obtain more accurate estimation and better video generation results. + + + +### (4) Run the UniAnimate model to generate videos + +#### (4.1) Generating video clips (32 frames with 768x512 resolution) + +Execute the following command to generate video clips: +``` +python inference.py --cfg configs/UniAnimate_infer.yaml +``` +After this, 32-frame video clips with 768x512 resolution will be generated: + + + +
