Spectral-Motion-Alignment (AAAI 2025)

This repository is the official implementation of SMA.
[AAAI 2025] SMA: Spectral Motion Alignment for Video Motion Transfer using Diffusion Models.
Geon Yeong Park*, Hyeonho Jeong*, Sang Wan Lee, Jong Chul Ye

SMA framework distills the motion information in frequency-domain. Our regularization includes (1) global motion alignment based on 1D wavelet-transform, and (2) local motion refinement based on 2D Fourier transform.

Setup

Requirements

For the preliminary proof of concepts, this repository is build upon VMC (w/ Show-1 backbone).

(1) Install VMC requirements

pip install -r requirements.txt

(2) Install wavelet libraries

• pytorch_wavelets

git clone https://github.com/fbcotter/pytorch_wavelets
cd pytorch_wavelets
pip install .

• PyWavelets

pip install PyWavelets

Usage

The following command will run "train & inference" at the same time:

accelerate launch train_inference.py --config configs/man_skate.yml

Additional Data

We benefit from video dataset released by VMC.

• PNG files: Google Drive Folder
• GIF files: Google Drive Folder

Hyperparameters

Most configurations follows VMC.

• ld_global: Weight for global motion alignment ($\lambda_{g}$ in the paper). Default 0.4

• ld_local: Weight for local motion refinement ($\lambda_{l}$ in the paper). Default 0.2

• num_levels: Number of levels in discrete wavelet transform. Default 2 for 8-frames input video, 3 for 16-frames input video

• ld_levels: Weight for the alignment of each wavelet coefficients. Default: [1]*(num_levels+1)

Shoutouts

• SMA is validated on various open-source video/image diffusion models: Show-1, Zeroscope-V2, Stable Diffusion, and ControlNet.
• SMA demonstrated its compatibility with four leading video-to-video frameworks: VMC, MotionDirector, Tune-A-Video, ControlVideo.
