Phase-based-Frame-Interpolation

This is my personal implementation of the paper "Phase-based frame interpolation for Video". To be precise, this implementation almost matches this MATLAB implementation. As claimed by the orginal author of the MATLAB code, the implementation is highly un-optimized. Nevertheless, I added GPU support to reduce the processing time while still maintaining the clarity of the method.

Also, if you use this implementation, you must cite the following paper:

S. Meyer, O. Wang, H. Zimmer, M. Grosse and A. Sorkine-Hornung
Phase-based frame interpolation for video
2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)

This implementation uses a version of pyrtools by Eero Simoncelli in Python modified by me. Please check this website for more information.
