The main part of the talk will introduce a number of techniques that reveal variations that are too small to be seen in regular video. I will introduce  Eulerian video magnification and show how simple temporal processing can amplify not just color changes but also spatial motion. I will then introduce a new approach based on complex-valued steerable pyramids that can better capture local motion and significantly improves the quality of the results. Finally, I will demonstrate that heart rate can be extracted from regular videos, not just by analyzing color variations but also by analyzing imperceptible head motion.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I will first give a brief overview of recent results about a compiler for high-performance image processing, an authoring tool for online video lectures, and Metropolis light transport.
