🔍 **MEMFOF** is a **memory-efficient optical flow method** for **Full HD video** that combines **high accuracy** with **low VRAM usage**.

✅ **Note:** This particular checkpoint is intended for submission to **Spring benchmark**.

## 🛠️ Usage

```shell
git clone https://github.com/msu-video-group/memfof.git
cd memfof
pip3 install -r requirements.txt
```

```python
import torch
from core.memfof import MEMFOF

device = "cuda" if torch.cuda.is_available() else "cpu"
model = MEMFOF.from_pretrained("egorchistov/optical-flow-MEMFOF-Tartan-T-TSKH-spring").eval().to(device)

with torch.inference_mode():
    example_input = torch.randint(0, 256, [1, 3, 3, 1080, 1920], device=device)  # [B=1, T=3, C=3, H=1080, W=1920]
    backward_flow, forward_flow = model(example_input)["flow"][-1].unbind(dim=1)  # [B=1, C=2, H=1080, W=1920]
```
