In this post, I’ll show how we can use Julia and my multi-scale image decomposition library, Pyramids.jl, to implement Phase-Based Frame Interpolation for Video, an algorithm from CVPR 2015. This assumes some familiarity with complex steerable pyramids. The paper The paper describes an algorithm for interpolating between video frames, with applications from smoother slow-motion video to creative animation effects. The algorithm itself is fairly straightforward. First, two complex steerable ...
