Sparse PCA-based Lagrangian Motion Magnification on Faces

The implementation of landmark-based, selective motion magnification can be found here. The sparse PCA-based decomposition and demo has been implemented by @cosmas-heiss and the RAFT training on faces for micro-expressions by @phflot.

Requirements

Setup anaconda via conda env create -f environment.yml. To reproduce the demo recording, the file EP04_04f.avi from the CASME II microexpression dataset is required.
