"This is a technical demo for face substitution technique. The application works in real time and it's developed using the opensource framework for creative coding openFrameworks: openFrameworks.cc The face tracking library returns a mesh that matches the contour of the eyes, nose, mouth and other facial features. That way the mesh obtained from a photo is matched to the face in the video.

"We extract heart rate and beat lengths from videos by measuring subtle head motion caused by the Newtonian reaction to the influx of blood at each beat. Our method tracks features on the head and performs principal component analysis (PCA) to decompose their trajectories into a set of component motions. It then chooses the component that best corresponds to heartbeats based on its temporal frequency spectrum. Finally, we analyze the motion projected to this component and identify peaks of the trajectories, which correspond to heartbeats. When evaluated on 18 subjects, our approach reported heart rates nearly identical to an electrocardiogram device. Additionally we were able to capture clinically relevant information about heart rate variability."
