pytorch-sepconv

This is a reference implementation of Video Frame Interpolation via Adaptive Separable Convolution [1] using PyTorch. Given two frames, it will make use of adaptive convolution [2] in a separable manner to interpolate the intermediate frame. Should you be making use of our work, please cite our paper [1].

Paper

For the Torch version of this work, please see: https://github.com/sniklaus/torch-sepconv
For a third-party fork with video support, consider: https://github.com/dagf2101/pytorch-sepconv

setup

To build the implementation and download the pre-trained networks, run bash install.bash and make sure that you configured the CUDA_HOME environment variable. After successfully completing this step, run python run.py to test it. Should you receive an error message regarding an invalid device function during execution, configure the utilized CUDA architecture within install.bash to something your graphics card supports.

usage

To run it on your own pair of frames, use the following command. You can either select the l1 or the lf model, please see our paper for more details. In short, the l1 model should be used for quantitative evaluations and the lf model for qualitative comparisons.

python run.py --model lf --first ./images/first.png --second ./images/second.png --out ./result.png
