Enhanced Eulerian video magnification

A post-processing technique is introduced to improve the Eulerian video magnification method, which is a state-of-the-art motion magnification method to manipulate small movements in videos based on spatio-temporal filtering. The proposed method use the Eulerian video magnification as a video spatio-temporal motion analyzer to get the pixel-level motion mapping. Then the input video pixels are warped based-on this mapping to amplify the motion. This processing does not involve pixel value modifying, which makes it supports larger amplification and is significantly less influenced by the frame noise.
