# kornia/defmo

Pretrained weights for **DeFMO** (Deblurring and Shape Recovery of Fast Moving Objects),
used by [`kornia.feature.DeFMO`](https://kornia.readthedocs.io/en/latest/feature.html).

DeFMO is an encoder–renderer network that takes a blurred image and background frame
as input and predicts the sharp object appearance and trajectory over time. CVPR 2021.
