Eulerian Video Magnification in Surveillance Systems

Abstract

In this article we look at the research behind Eulerian Video Magnification, its beginnings and innovations that lead to its potential use in real time heart rate measurement. The spatial amplitude changes are exaggerated using EVM in conjuncture with face detection using the Viola-Jones algorithm to allow measurement of moving subjects. Fourier transform on the temporal signal of pooled skin pixels then yields heart rate. The algorithm is tested against movement and at different distances.
