ComfyUI-FirstOrderMM

ComfyUI-native nodes to run First Order Motion Model for Image Animation and its non-diffusion-based successors.

https://github.com/AliaksandrSiarohin/first-order-model

Now supports:

1. Face Swapping using Motion Supervised co-part Segmentation:
2. Motion Representations for Articulated Animation
3. Thin-Plate Spline Motion Model for Image Animation
4. Learning Motion Refinement for Unsupervised Face Animation
5. Facial Scene Representation Transformer for Face Reenactment

FSRT

Arguments

FOMM

• relative_movement: Relative keypoint displacement (Inherit object proporions from the video)
• relative_jacobian: Only taken into effect when relative_movement is on, must also be on to avoid heavy deformation of the face (in a freaky way)
• adapt_movement_scale: If disabled, will heavily distort the source face to match the driving face
• find_best_frame: Find driving frame that best match the source. Split the batch into two halves, with the first half reversed. Gives mixed results. Needs to install face-alignment library.

Part Swap

• blend_scale: No idea, keeping at default = 1.0 seems to be fine
• use_source_seg: Whether to use the source's segmentation or the target's. May help if some of the target's segmentation regions are missing
• hard_edges: Whether to make the edges hard, instead of feathering
• use_face_parser: For Seg-based models, may help with cleaning up residual background (should only use 15seg with this). TODO: Additional cleanup face_parser masks. Should definitely be used for FOMM models
• viz_alpha: Opacity of the segments in the visualization

Articulate

Doesn't need any

Spline

• predict_mode: Can be
  • relative: Similar to FOMM's relative_movement and adapt_movement_scale set to True
  • standard: Similar to FOMM's adapt_movement_scale set to False
  • avd: similar to relative, may yield better but more "jittery/jumpy" result
• find_best_frame: Same as FOMM

MRFA

• model_name: vox or celebvhq, which is trained on (presumably) the vox256 and celebhq datasets respectively.
• use_relative: Whether to use relative mode or not (absolute mode). Absolute mode is similar to FOMM's adapt_movement_scale set to False
• relative_movement, relative_jacobian, adapt_movement_scale: Same as FOMM

FSRT

This model takes the longest to run. The full Damedane example takes ~6 minutes

• model_name: vox256 or vox256_2Source, which is trained on (presumably) the vox256 and vox256+celebhq datasets respectively.
• use_relative: Use relative or absolute keypoint coordinates
• adapt_scale: Adapt movement scale based on convex hull of keypoints
• find_best_frame: Same as FOMM
• max_num_pixels: Number of parallel processed pixels. Reduce this value if you run out of GPU memory

Installation

1. Clone the repo to ComfyUI/custom_nodes/

git clone https://github.com/FuouM/ComfyUI-FirstOrderMM.git

2. Install required dependencies

pip install -r requirements.txt

Optional: Install face-alignment to use the find_best_frame feature:

pip install face-alignment

Models

FOMM and Part Swap

FOMM: vox and vox-adv from

• AliaksandrSiarohin/first-order-model
• graphemecluster/first-order-model-demo

Part Swap

• vox-5segments
• vox-10segments
• vox-15segments
• vox-first-order (partswap)

These models can be found in the original repository Motion Supervised co-part Segmentation

Place them in the checkpoints folder. It should look like this:

place_checkpoints_here.txt
vox-adv-cpk.pth.tar
vox-cpk.pth.tar

vox-5segments.pth.tar
vox-10segments.pth.tar
vox-15segments.pth.tar
vox-first-order.pth.tar

For Part Swap, Face-Parsing is also supported (Optional) (especially when using the FOMM or vox-first-order models)

• resnet18 resnet18-5c106cde: https://download.pytorch.org/models/resnet18-5c106cde.pth
• face_parsing 79999_iter.pth: https://github.com/zllrunning/face-makeup.PyTorch/tree/master/cp

Place them in face_parsing folder:

face_parsing_model.py
...
resnet18-5c106cde.pth
79999_iter.pth

Notes:

• For Spline and FSRT, to use find_best_frame, follow above instructions to install face-alignment with its models.
• For FSRT, you must download kp_detector
