Description:
Motion magnification from video is a cool technique to amplify motions that would otherwise be invisible to the human eye. A few nice examples can be seen here: http://people.csail.mit.edu/mrub/vidmag/
At the BIOS lab of UT, several videos of live engineered heart tissue have been captured. For certain tissues, the contractions are very small or not visible to the naked eye, but can be magnified using the motion magnification technique. Goal of this assignment will be to quantify and visualise the motion magnitude and the frequencies present in the videos, so that to characterize motion properties and suitability of tissues for further use in drug tests or artificial tissue growing.
An optional use-case would be to apply this technique to video footage of a bridge under dynamic load (fancy wording for jumping on the bridge deck). Previous experiments using accelerometers have provided the ground truth data for frequency response of the bridge deck. The use-case bridge is the Tankinkbrug, situated between Delden en Goor. Part of this assignment will be to capture uncompressed video footage of the bridge using a machine vision camera.
