We present Eulerian Video Magnification, a computational technique for visualizing subtle color and motion variations in ordinary videos by making the variations larger. It is a microscope for small changes that are hard or impossible for us to see by ourselves.

Med ett Processen, som kallas Eulerian Video Magnification, extraherar "dold an indicative manner. Our method, which we call Eulerian Video Magnification, takes a standard video sequence as input, and applies spatial decomposition, followed by temporal filtering to the The resulting signal is then amplified to reveal hidden information. Eulerian Video Magnification code Matlab code and executables implementing Eulerian video processing for amplifying color and motion changes. Phase Based Video Motion Processing code Matlab code implementing the new and improved phase-based motion magnification pipeline. Our method, which we call Eulerian Video Magniﬁcation, takes a standard video sequence as input, and ap- plies spatial decomposition, followed by temporal ﬁltering to the frames. The resulting signal is then ampliﬁed to reveal hidden in- formation. We present Eulerian Video Magnification, a computational technique for visu- alizing subtle color and motion variations in ordinary vid- eos by making the variations larger.

Reconstruction Eulerian video magnification Output video r n time y time y T Figure 2: Overview of the Eulerian video magniﬁcation framework. The system ﬁrst decomposes the input video sequence into different spatial frequency bands, and applies the same temporal ﬁlter to all bands. The ﬁltered spatial bands are then ampliﬁed by a Hao-Yu Wu, Michael Rubinstein, Eugene Shih, John Guttag, Frédo Durand, William T. Freeman Eulerian Video Magnification for Revealing Subtle Changes in the World ACM Transactions on Graphics, Volume 31, Number 4 (Proc. SIGGRAPH), 2012 The first Eulerian method to amplify small motions and color variations in videos. a new video in which the variations in θ are larger by a factor 1 + α. This shows that linear Eulerian video magnification can be used to magnify many subtle, temporal phenomena. 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.

Selected Results In 2012, research reemerged from an MIT group with some returning members from the 2005 team as well as some new members. This group introduced a new way for revealing subtle changes in the world, which resulted in the Eulerian Video Magnification technique used in this project. Eulerian video magnification in Matlab.

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. Researchers at MIT developed Eulerian Video Magnification (EVM), a program that uses temporal and spatial filtering to magnify subtle changes in video recordings.
