🔍 **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 real-world videos** — it is trained with **higher diversity and robustness** in mind.

## 🛠️ Usage

Install MEMFOF via the package manager:

```shell
pip3 install git+https://github.com/msu-video-group/memfof
```

Then use the following snippet to compute backward and forward optical flow for three consecutive frames:

```python
import torch
from memfof import MEMFOF

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

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