This is the test code reference implementation of Deep Iterative Frame Interpolation for Full-frame Video Stabilization [1], using PyTorch. This work proposes a full-frame video stabilization method via frame interpolation techniques, making use of a self-supervised deep learning approach. Should you make use of our work, please cite our paper [1].

Our paper can be found in the <a href="https://dl.acm.org/doi/abs/10.1145/3363550">ACM Digital Library</a> and <a href="https://arxiv.org/abs/1909.02641">arXiv</a>.

Setup

We used the following python and package versions:

python==3.5.6 torch==1.0.0 cupy==4.1.0 pillow==5.2.0 numpy==1.15.2 matplotlib==3.0.0 pypng==0.0.20 opencv-contrib-python==4.1.0.25 CUDA==9.0

You may require to setup the correlation package for computing the cost volume module in PWC-Net. If required, please follow the instructions in <a href="https://github.com/vt-vl-lab/pwc-net.pytorch">vt-vl-lab/pwc-net</a>.

Usage

You can run python run_seq2.py --cuda --n_iter 3 --skip 2 to obtain example results on a sample given in the data folder, which will be saved in the output folder.

By default, our experiments were done with 3 iterations and skip parameter of 2. This can be customized by adjusting the --n_iter and --skip options.

We also provide code for making .avi videos from output frames, and a reference code for quality metrics.
