This is a reference implementation of Video Frame Interpolation via Adaptive Separable Convolution [1] using Torch. 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].
For the PyTorch version of this work, please see: https://github.com/sniklaus/pytorch-sepconv
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 th run.lua to test it. Should you receive an error message regarding an invalid device function during execution, configure the utilized CUDA architecture within CMakeLists.txt to something your graphics card supports.
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.
th run.lua -model lf -first ./images/first.png -second ./images/second.png -out ./result.png
