Magnification is a C++ implemention of the paper Eulerian Video Magnification for Revealing Subtle Changes in the World.. This project uses much of the C++ implementation from kgram007/Eulerian-Motion-Magnification, but removes some redundant steps and adds concurrency where possible to make processing a streaming video more performant. So I've actually tried to implement Eulerian video magnification myself, albeit using Python, because I believe when I first looked into this, ~5 year ago, the code was MatLab only. I was really excited about it, because, as a cardiologist, I immediately thought we could use this to identify irregular heart beats in the patient waiting room, for example. Eulerian video magnification in Matlab.

For this video we tuned the temporal filter to a frequency band that includes the heart rate-0.88 Hz (53 bpm)-and set the amplification factor to a = 10. To reduce motion Project 2: Eulerian Video Magnification Jun-Yan Zhu. Overview In this project, I implemented a recent SIGGRAPH paper "Eulerian Video Magnification" [Wu et al, 2012] from MIT Computer Graphics group. This paper explores the same topic "Motion magnification" as [Liu et al. 2005] but in a different perspective (Eulerian analysis).

Overview. In this project, I finished a MATLAB framework of the SIGGRAPH 2012 paper "Eulerian Video Magnification for Revealing Subtle Changes in the World" from MIT CSAIL. This project is named as Eulerian Video Magnification to reveal temporal image variations that tend to be difficult to visualize, that one can amplify blood flow and low-amplitude motion with Eulerian Magnification without

It is agnostic to the underlying imaging model and can even work in cases where brightness constancy is not true as long as the changes are small. 2.3.
