# MIMO: Controllable Character Video Synthesis

MIMO enables controllable character video synthesis with spatial decomposed modeling. Upload a reference image and pose video to generate realistic character animations.

## Features

- 🎭 Controllable character animation
- 🖼️ Reference image-based generation
- 🕺 Pose-guided video synthesis
- ⚡ Optimized for HuggingFace Spaces

## Usage

1. Upload a reference character image
2. Upload a pose video or select from examples
3. Click "Generate Video" to create your animation

The model will automatically download weights from HuggingFace Hub on first use.

## Model Details

Based on the CVPR 2025 paper "MIMO: Controllable Character Video Synthesis with Spatial Decomposed Modeling"

- Model weights: ~8GB (downloaded at runtime)
- Supports both CPU and GPU inference
- Optimized for HuggingFace Spaces deployment
